Technical Data

Noise values and vibration values (trial vector sum) according to EN60745-2-1:

The vibration and/or noise emission level given in this information sheet has been measured in accordance with a standardized test given in EN60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

WARNING: The declared vibration and/or noise emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration and/or noise emission may differ. This may significantly increase the exposure level over the total working period. An estimation of the level of exposure to vibration and/or noise should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration and/or noise such as: maintain the tool and the accessories, keep the hands warm (relevant for vibration), organization of work patterns.

GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains‑operated (corded) power tool or battery‑operated (cordless) power tool.

1. Work Area Safety

2. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

3. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

4. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

5. Electrical Safety

6. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

7. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

8. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

9. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

10. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord  suitable for outdoor use reduces the risk of electric shock.

11. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

12. Personal Safety

13. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

14. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non‑skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

15. Prevent unintentional starting. Ensure the switch is in the off‑position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.

16. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

17. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

18. Dress properly. Do not wear loose clothing or jeweler. Keep your hair and clothing away from moving parts. Loose clothes, jeweler or long hair can be caught in moving parts.

19. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust‑related hazards.

20. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

21. Power Tool Use and Care

22. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

23. Do not use the power tool if the switch does not turn
    it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

24. Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

25. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

26. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

27. Keep cutting tools sharp and clean. Properly
    maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

28. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

29.  Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping  surfaces do not allow for safe handling and control of the tool in unexpected situations. surfaces do not allow for safe handling and control of the tool in unexpected situations.

30. Battery Tool Use and Care

31. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

32. Use power tools only with specifically designated
    battery packs. Use of any other battery packs may create a risk of injury and fire.

33. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

34. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

35. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

36. Do not expose a battery pack or tool to fire or
    excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.

37. Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

38. Service

39. Have your power tool serviced by a qualified repair person using only identical replacement parts. This  will ensure that the safety of the power tool is maintained.

40. Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Additional Specific Safety Rules for Drills/Drivers/ Hammer drills

• Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
• Use the auxiliary handles, if supplied with the tool. Loss of control can cause personal injury.
• Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.
• Hold the power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory or fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

Safety Instructions When Using Long Drill Bits

• Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
• Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
• Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.
• Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
• Wear ear protectors when hammering for extended periods of time. Prolonged exposure to high intensity noise can cause hearing loss. Temporary hearing loss or serious ear drum damage may result from high sound levels generated by hammer drilling.
• Wear safety goggles or other eye protection. Hammering and drilling operations cause chips to fly. Flying particles can cause permanent eye damage.
• Hammer bits and tools get hot during operation. Wear gloves when touching them.

Residual Risks
In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

• Impairment of hearing.
• Risk of personal injury due to flying particles.
• Risk of burns due to accessories becoming hot during operation.
• Risk of personal injury due to prolonged use.

SAVE THESE INSTRUCTIONS

Chargers
DEWALT chargers require no adjustment and are designed to be as easy as possible to operate.

Electrical Safety
The electric motor has been designed for one voltage only. Always check that the battery pack voltage corresponds to the voltage on the rating plate. Also make sure that the voltage of your charger corresponds to that of your mains. Your DEWALT charger is double insulated in accordance with EN60335; therefore no earth wire is required. If the supply cord is damaged, it must be replaced only by DEWALT or an authorized service organization.

Mains Plug Replacement (U.K. & Ireland Only)
If a new mains plug needs to be fitted:

• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the earth terminal. Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 3 A.

Using an Extension Cable
An extension cord should not be used unless absolutely necessary. Use an approved extension cable suitable for the power input of your charger (see Technical Data). The minimum conductor size is 1 mm2; the maximum length is 30 m. When using a cable reel, always unwind the cable completely.

• In case of damaged power supply cord, the supply cord must be replaced immediately by the manufacturer, its service agent or similar qualified person to prevent any hazard.
• Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect two chargers together.
• The charger is designed to operate on standard 230V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.

Charging a Battery (Fig. B)

1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack  1  into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink repeatedly indicating that the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button  2  on the battery pack.

NOTE: To ensure maximum performance and life of lithium‑ion battery packs, charge the battery pack fully before first use.

Charger Operation
Refer to the indicators below for the charge status of the battery pack.

• The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery by refusing to light.

NOTE: This could also mean a problem with a charger. If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.

Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life. A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.
The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System
XR Li‑Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge. The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium‑ion battery pack on the charger until it is fully charged.
Wall Mounting
These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 5.5 mm of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non‑metallic brush. Do not use water or any cleaning solutions. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

  (such as outside sheds or metal buildings in winter), or reach or exceed 40 ˚C (104 ˚F) (such as outside sheds or metal buildings in summer).

• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium‑ion battery packs are burned.
  • If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.

• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persists, seek medical attention.

WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
WARNING: Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Electric shock or electrocution

may result. Damaged battery packs should be returned to service center for recycling.
WARNING: Fire hazard. Do not store or carry the battery pack so that metal objects can contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.
CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over.

Transportation

WARNING: Fire hazard. Transporting batteries can possibly cause fire if the battery terminals inadvertently come in contact with conductive materials. When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Lithium‑ion batteries should not be put in checked baggage. DEWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium‑ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria. In most instances, shipping a DEWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium‑ion battery with an energy rating greater than 100 Watt Hours (Why) will require being shipped as fully regulated Class 9. All lithium‑ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DEWALT does not recommend air shipping lithium‑ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100 Wh. Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper’s responsibility to consult the latest regulations for packaging, labeling/marking and documentation requirements. The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer’s responsibility to ensure that its activities comply with the applicable regulations.

Transporting the FLEXVOLTTM Battery
The DEWALT FLEXVOLTTM battery has two modes: Use and Transport.

Use Mode:
When the FLEXVOLTTM battery stands alone or is in a DEWALT 18V product, it will operate as an 18V battery. When the FLEXVOLTTM battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.

Transport Mode:

When the cap is attached to the FLEXVOLTTM battery, the battery is in Transport mode. Keep the cap for shipping. When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a lower Watt hour (W h) rating as compared to 1 battery with a higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries. For example, the Transport Example of Use and Transport Label Marking Why rating might indicate 3 x 36 Why, meaning 3 batteries of 36 Why each. The Use Why rating might indicate 108 Why (1 battery implied).

Storage Recommendations

1. The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold. For optimum battery performance and life, store battery packs at room temperature when not in use.
2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use. Labels on Charger and Battery Pack In addition to the pictographs used in this manual, the labels on the charger and the battery pack may show the following pictographs:

• Read instruction manual before use.
• See Technical Data for charging time.
• Do not probe with conductive objects.

Torque Adjustment Collar/Electronic Clutch (Fig. A)
Your tool has an electronic adjustable torque screwdriver mechanism for driving and removing a wide array of fasteners. Circling the torque adjustment collar  5  are numbers. These numbers are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque and the larger the fastener which can be driven. To select any of the numbers, rotate until the desired number aligns with the arrow.

WARNING: When the torque adjustment collar is in the drill or hammer drill positions, the drill will not clutch. The drill may stall if overloaded, causing a sudden twist.

Three‑Speed Gearing (Fig. A)
The three‑speed feature of your tool allows you to shift gears for greater versatility. To select speed 1 (highest torque setting), turn the tool off and permit it to stop. Slide the gear shifter  8  all the way forward. Speed 2 (middle torque and speed setting) is in the middle position. Speed 3 (highest speed setting) is to the rear.

NOTE: Do not change gears when the tool is running. Always allow the drill to come to a complete stop before changing gears. If you have trouble changing gears, make sure that the gear shifter is engaged in one of the three speed settings. If the speed shifter becomes stuck or is difficult to select the desired gear, pull the variable speed trigger switch  3  to rotate the motor, then select the gear. LED Work light (Fig. E) The LED work light  9 and its work light switch  10  are located on the foot of the tool. The work light is activated when the trigger switch is depressed. The low, medium, and spotlight modes can be changed by moving the switch on the foot of the tool. If the trigger switch remains depressed, the work light will remain on in all modes. When on low and medium settings, the beam will automatically turn off 20 seconds after the trigger switch is released.

Spotlight Mode
The high setting is the spotlight mode. The spotlight will run for 20 minutes after the trigger switch is released. Two minutes before the spotlight will shut off, it will flash twice and then dim. To avoid the spotlight shutting off, lightly tap the trigger switch.

• WARNING: While using the work light in medium or spotlight mode, do not stare at the light or place the drill in a position which may cause anyone to stare into the light. Serious eye injury could result.

• CAUTION: When using the tool as a spotlight, be sure
  it is secured on a stable surface where it will not cause a tripping or falling hazard.

• CAUTION: Remove all accessories from the chuck before using the drill as a spotlight. Personal injury or property damage could result.

Low Battery Warning
When in spotlight mode and the battery is nearing complete discharge, the spotlight will flash twice and then dim. After two minutes, the battery will be completely discharged and the drill will immediately shut down. At this point, replace with a charged battery.

WARNING: To reduce the risk of injury, always have a back‑up battery or secondary lighting available if the situation warrants it.

Keyless Single Sleeve Chuck (Fig. C)

WARNING: Do not attempt to tighten drill bits (or
any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch and remove the battery from the tool when changing accessories.
WARNING: Always ensure the bit is secure before starting the tool. A loose bit may eject from tool causing possible personal injury. Your tool features a keyless chuck  6  with one rotating chuck sleeve  7  for one‑handed operation of the chuck. To insert a drill bit or other accessory, follow these steps.

1. Turn tool off and remove the battery pack.
2. Grasp the black sleeve of the chuck with one hand and use the other hand to secure the tool. Rotate the sleeve anticlockwise (as viewed from the front) far enough to accept the desired accessory.
3. Insert the accessory about 19 mm into the chuck and tighten securely by rotating the chuck sleeve clockwise with one hand while holding the tool with the other hand. Continue to rotate the chuck sleeve until several ratchet clicks are heard to ensure full gripping power.
   NOTE: Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for maximum tightness.

To release the accessory, repeat steps 1 and 2 above.

OPERATION

Instructions for Use

WARNING: Always observe the safety instructions and applicable regulations.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start‑up can cause injury.

Proper Hand Position (Fig. D)

• WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.
• WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction. Proper hand position requires one hand on the main handle   15 , with the other hand on the side handle  14  to control the twisting action of the drill.

Screwdriver Operation (Fig. A)

1. Select the desired speed/torque range using the three‑speed gear shifter  8  on the top of the tool. If using the torque adjustment collar  5 , initially set the three‑speed gear shifter to speed 2 or 3. This ensures effective control over the fastener allowing the screw to be seated correctly and set to specification. Speed 1 will provide the same clutching torque as speeds 2 and 3. However, for optimum performance of the electronic clutch, speeds 2 and 3 are preferred.
   N OTE: Use the lowest torque setting (1) first and increase the number through to the highest setting (11) to seat the fastener at the desired depth. The lower the number, the lower the torque output.

2. Reset the torque adjustment collar  5  to the appropriate number setting for the torque desired. Make a few practice runs in scrap or unseen areas to determine the proper position of the torque adjustment collar.

NOTE: The torque adjustment collar may be set to any number at any time.

Drill Operation (Fig. A)

WARNING: TO REDUCE THE RISK OF PERSONAL INJURY, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood “back‑ up” block to prevent damage to the material.

1. Select the desired speed/torque range using the gear shifter  8  to match the speed and torque to the planned operation. Set the torque adjustment collar  5  to the
   drill symbol.

2. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high‑speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry.

3. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit biting, but do not push hard enough to stall the motor or deflect the bit.

4. Hold tool firmly with both hands to control the twisting action of the drill.

5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN DAMAGE THE DRILL.

6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming.

Hammer drill Operation (Fig. A)

1. Select the desired speed/torque range using the gear shifter to match the speed and torque to the planned operation. Set the torque adjustment collar  5  to the hammer symbol.
2. Select the high speed 3 setting by sliding the gear shifter  8  back (away form the chuck).
3. When drilling, use just enough force on the hammer to keep it from bouncing excessively. Prolonged and too much force on the hammer will cause slower drilling speeds and potential overheating.
4. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed.
5. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole.
6. For masonry, use carbide‑tipped bits or masonry bits. A smooth, even flow of dust indicates the proper drilling rate.
