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.

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 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.
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.
When possible, thread the workpiece
before cutting it to the final length
to eliminate the damaged area.
3. Insert the Die into the Die Wrench.
Note: An adapter ring is provided
for the smaller die sizes.
4. 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.

Die
5. Place the chamfered side of the Die onto
the workpiece, being careful to precisely
align the Die perpendicular to the rod.
6. 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.
7. 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.
8. Then turn the Die counterclockwise
completely off the rod.
Maintenance
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.
2. Store tools in the provided case in a
secure location, out of the reach of
children, to protect them from moisture.
