IMPORTANT SAFETY INFORMATION
Use Precautions
-
Wear ANSI-approved safety goggles and heavy-duty work gloves during use.
-
Keep work area clean and well lit.
-
Keep bystanders out of the area during use.
-
Do not use when tired or when under the influence of alcohol, drugs or medication.
-
This product is not a toy. Do not allow children to play with or near this item.
-
Use as intended only.
-
Inspect before every use; do not use if parts are loose or damaged. Do not use cracked or chipped tap/die.
-
Keep the handles clean, dry, and free from oil and grease at all times.
-
The flutes on these tools are sharp and can cut you. Handle with care.
-
Do not use any high-speed means, such as a lathe or drill press, to cut threads with these Taps and Dies. High-speed use will void the warranty and may overheat the tool, causing loss of heat-treatment and premature failure.
-
aps and Dies are heat-treated, and not designed to be sharpened. After considerable use and with corrosion buildup
these tools may lose their cutting edge. -
Use clamps (sold separately) or other practical ways 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.
-
Do not apply excessive force on the cutters. Allow the tool to do the work. Use cutting oil hen tapping or threading hard materials.
-
Maintain product labels and nameplates. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
Operation Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.
Before using either taps or dies, test the material to determine that it is not hardened by attempting to mark it with a file.
- If the material marks with a file, material should be cuttable.
- If the material will not mark with a file, do not cut threads to avoid tool damage.
Tap Instructions
TAPS are used to cut (tapping) or clean (chase) internal threads into a pre- drilled hole, such as in a nut or component part.
- To cut an internal thread, first select the tap of the desired size and have lubricating or cutting oil ready for use.
- The proper hole size is very important to successfully cut good threads. An oversized hole will result in shallow threads, and poor holding power. An undersized hole may cause the tap to wear prematurely or break. The correct hole size is marked on the shank of each tap.
- Insert the square end of the Tap into the Tap Wrench, turn the threaded side of the Tap Wrench to secure the Tap firmly.
- Precisely align the tap with the direction of the hole. THIS IS ESSENTIAL. The first cut will help determine the accuracy of the entire finished thread.
- Start turning the Tap clockwise, keeping the Tap aligned with the hole. As the Tap turns, it will bite into the metal and create threads.
- After every 1/4 to 1/2 turn of progress, depending on material hardness, rotate the Tap counterclockwise an equal amount to prevent chips from building up in the hole and breaking the tap.
- Lubricate amply with cutting oil while tapping. Proper lubrication will result in smoother threads, and increased tool life. Continue tapping until the Tap passes through the workpiece, or the desired thread depth is reached.
- Carefully thread the tap out backwards and clean out any chips from the hole.
Die Instructions
DIES are used to cut (threading) or clean (chase) external threads, such as on a screw or threaded rod.
NOTE: It will be easier to start the Die correctly if the end of the work material is slightly chamfered with a grinder or file (not included).
-
Select the proper Die size for the rod to be threaded. The Die can be no larger than the rod stock, and should be .005″ to .010″ smaller. Oversized rod stock may damage the die, and will make turning it difficult. Slightly undersized rod stock makes turning the die easier, and will result in good threads for most applications.
-
Secure the workpiece in a vise or other fixture (not included). Ensure that the workpiece will not move or turn while it is being threaded. Note that the workpiece may be damaged by the vise during the threading process. When possible, thread the workpiece before cutting it to the final length to eliminate the damaged area.
-
Insert the Die into the Die Wrench.
Align the groove on the side of the Die with the Screw on the Die Holder. Tighten the screw using the included Screwdriver. Use the Screw on side of the Die Wrench to secure the Die firmly in place. See Figure A:
-
Place the chamfered side of the Die onto the workpiece, being careful to precisely align the Die perpendicular to the rod.
-
Begin turning the Die clockwise. The cutting edges will begin to bite into the material, and the Die will begin to thread itself onto the rod.
-
As you progress, apply lubrication, using a high-quality cutting oil. As with the Tap, reverse the Die to clear the shavings after every 1/4 to 1/2 turn of progress, depending on material hardness. Continue this forward and back process, using proper lubrication, until you have cut the desired length of threads.
-
Then turn the Die counterclockwise completely off the rod.
Maintenance and Servicing
-
1. Clean immediately after use and apply a light layer of oil or grease to prevent corrosion.
Note: The carbon steel parts of this set are susceptible to corrosion. Even light corrosion may reduce effectiveness.
Record Serial Number Here: -
