Harbor Freight TDST-41 SAE Professional Tap and Die Set Owner’s Manual

Harbor Freight TDST-41 SAE Professional Tap and Die Set

Product Information

The product is a tap-and-die set available in two variants: 41pc MM Tap and Die and 41pc SAE Tap and Die. Both variants are made of tungsten molybdenum tool steel and come with tapered coarse and fine threads. The MM variant includes sizes ranging from M3 x 0.5 to M12 x 1.75 while the SAE variant includes sizes ranging from 4-40 to 1/2-13. The set also includes pipe tap and die sizes such as 1/8-28BSPT, 1/8-27NPT, and M4 x 0.7. The product should be used with ANSI-approved safety goggles and heavy-duty work gloves. The work area should be well-lit and kept clean. Bystanders should not be allowed in the area during use. The product should not be used when tired or under the influence of alcohol, drugs, or medication. Children should not be allowed to play with or near the product. The product should be inspected before every use and should not be used if parts are loose or damaged. The handles should be kept clean, dry, and free from oil and grease at all times.

Product Usage Instructions

1. Wear ANSI-approved safety goggles and heavy-duty work gloves during use.
2. Keep the work area clean and well-lit.
3. Keep bystanders out of the area during use.
4. Do not use when tired or when under the influence of alcohol, drugs or medication.
5. Do not allow children to play with or near this item.
6. Inspect before every use; do not use if parts are loose or damaged. Do not use cracked or chipped tap/die.
7. Keep the handles clean, dry, and free from oil and grease at all times.
8. Handle with care as the flutes on these tools are sharp and can cut you.
9. 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.
10. After considerable use and with corrosion buildup these tools may lose their cutting edge. Taps and Dies are heat-treated and not designed to be sharpened.
11. 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.
12. Do not apply excessive force on the cutters. Allow the tool to do the work. Use cutting oil when tapping or threading hard materials.
13. Maintain product labels and nameplates. These carry important safety information. If unreadable or missing, contact HarborFreight Tools for a replacement.
14. Cleaning (Chasing) damaged threads with either a tap or die will REMOVE material from the existing threads. Specialized thread-correcting tools (not included) should be used to repair damaged threads on critical components.

IMPORTANT SAFETY INFORMATION

Use Precautions

1. Wear ANSI-approved safety goggles and heavy-duty work gloves during use.
2. Keep work area clean and well lit.
3. Keep bystanders out of the area during use.
4. Do not use when tired or when under the influence of alcohol, drugs or medication.
5. This product is not a toy. Do not allow children to play with or near this item.
6. Use as intended only.
7. Inspect before every use; do not use if parts are loose or damaged. Do not use cracked or chipped tap/die.
8. Keep the handles clean, dry, and free from oil and grease at all times.
9. The flutes on these tools are sharp and can cut you. Handle with care.
10. 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.
11. Taps 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.
12. 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.
13. Do not apply excessive force on the cutters. Allow the tool to do the work. Use cutting oil when tapping or threading hard materials.
14. 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, the 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 (chasing) internal threads into a pre‑drilled hole, such as in a nut or component part.

1. To cut an internal thread, first, select the tap of the desired size and have lubricating or cutting oil ready for use.
2. 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. Reference the tap thread chart for proper hole sizes.
3. Insert the square end of the Tap into the Tap Wrench, and turn the threaded side of the Tap Wrench to secure the Tap firmly.
4. 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.
5. 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.
6. 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.
7. 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.
8. Carefully thread the tap out backward 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).

1. Select the proper Die size for the rod to be threaded. The rod stock can be no larger than the thread size of a Die and should be .005″ to .010″ smaller. Oversized rod stock may damage the Die, and will make thread cutting difficult. Slightly undersized rod stock makes turning the Die easier, and will result in good threads for most applications.
2. 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. Avoid clamping on critical surfaces and on threads.
3. Insert the Die into the Die Wrench with the text facing outward. Tighten the screw using the included Screwdriver. Use the Screw on side of the Die Wrench to secure the Die firmly in place.
4. Place the chamfered side of the Die onto the workpiece, being careful to precisely align the Die perpendicular to the rod.
5. 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.
6. 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.
7. 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.
2. Store tools in the provided case in a secure location, out of the reach of children, to protect them from moisture.

Note: The hardened tool steel parts of this set are susceptible to corrosion. Even light corrosion may reduce effectiveness.
