Important Safety Information

1. 

Wear ANSI-approved safety goggles and 
heavy-duty work gloves during use.

2. 

Keep bystanders out of the area during use.

3. 

Do not use when tired or when under 
the influence of drugs or medication.

4. 

This product is not a toy.  Do not allow 
children to play with or near this item.

5. 

Use as intended only.

6. 

Keep work area clean and well lit.

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 (not included) 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.

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.

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.  The correct hole size is 
marked on the shank of each tap.

3. 

Insert the square end of the Tap into the 
Tap Wrench, 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 backwards 
and clean out any chips from the hole.
