Hand Tap set of 2 pieces DIN 2181 HSS-G - M 14 x 1.5

• Cut internal threads by hand in maintenance, fitting work, and workshop production.
• Use with a tap wrench to control torque and keep the tap aligned to the hole axis.
• Use suitable cutting fluid and remove chips from the flutes to avoid scoring of the new thread.
• Process: manual driving or assisted driving depending on your holder and machine setup.
• Use: thread cutting, re tapping, and thread cleaning depending on condition.

Note Core hole quality and alignment have a direct effect on thread accuracy. Use cutting fluid suitable for the material.

• Supports thread cutting in common workshop materials with suitable cutting fluid.
• Good solution for threaded holes in fixtures and assemblies.
• Two piece set reduces tool changes compared with longer sequences.
• Straightforward handling with a tap wrench.

• Cutting load increases in hard materials and can require a different tap material or geometry.
• Manual tapping is slower and more operator dependent than machine tapping.

1. Check that the core hole is drilled and deburred and that the entry is lightly chamfered.
2. Clamp the workpiece securely so the hole axis stays stable during threading.
3. Mount the first tap in a tap wrench and apply suitable cutting fluid to the hole.
4. Align the tap to the hole axis and start cutting with controlled torque.
5. Advance the tap gradually and reverse briefly at intervals to clear chips from the flutes.
6. Remove the first tap and clean the hole to remove chips and residual fluid.
7. Mount the second tap and repeat the cutting process to bring the thread to final form.
8. Remove the tap, clean the new thread, and check fit with the matching screw.

How do you select the correct hand tap set for your thread?

Match the thread designation and standard in the product name to your required internal thread and the mating screw.

Which wrench is suitable for hand taps?

Use a tap wrench that holds the square drive securely and supports controlled torque and alignment.

What is the most common cause of poor thread quality when hand tapping?

Misalignment at the start is common, so focus on keeping the tap square to the hole axis and keeping the hole clean from chips.

How do you reduce the risk of tap breakage in manual use?

Use suitable cutting fluid, avoid side loading, and stop if torque rises suddenly so you can check alignment and chip evacuation.
