Machine tap set DIN 371/376 B Universal M3–M12 HSS‑Co by TECWERK — vapour‑coated, universal type

Machine tap set DIN 371/376 B Universal M3–M12 HSS‑Co is a universal machine tapping kit for metric ISO threads, designed for industrial workshop and maintenance applications

• HSS‑Co for enhanced wear resistance
• Universal kit M3–M12 covers common sizes
• Vapour‑coated for lower friction
• Tolerance ISO2 (6H) for precision fit

Consistent cutting performance for repetitive production

The kit is built around HSS‑Co, a cobalt‑alloyed high‑speed steel that offers improved hot‑hardness and wear resistance compared with standard HSS. The combination of this HSS‑Co substrate with a vapour‑coated surface reduces friction and heat build‑up during machine tapping, which extends tool life and stabilises cycle times. The ground flank relief reduces the risk of chatter and promotes cleaner chip evacuation when used in appropriate tapping machines, translating to fewer rejects and less secondary rework.

Broad material compatibility and precision to standard

Designed to produce ISO metric threads in compliance with DIN 371/376 and DIN 13 sheet 1, the set meets the Tolerance ISO2 (6H) specification for reliable fit in assembly work. The contents cover the most common thread sizes from M3–M12 in a 7‑piece set, making it suitable for machining steel, stainless steel, spheroidal cast iron and non‑ferrous metals. The universal geometry offers a good balance between cutting edge robustness and chip control, which helps maintain dimensional accuracy across mixed‑material batches.

Practical advantages that improve workshop flow

A universal set of machine taps reduces tool changes and simplifies inventory: one compact kit supplies the majority of small to medium thread demands on a production line or service bench. The characteristic green ring marking aids rapid visual identification of the series, speeding up tool selection during fast‑paced operations. With machine‑grade design and consistent tolerances, the kit supports reproducible thread quality and reduces stoppages caused by incorrect or worn taps.

Handling, setup and maintenance explained

The taps are intended for machine tapping; correct spindle alignment, feed rate and lubrication are essential for achieving the stated tool life. The vapour‑coated surface lowers adhesion and eases chip flow, but adherence to recommended cutting parameters and coolant or cutting fluid use remains important for stainless and alloyed steels. Storing the kit in its case and checking each tap for wear before use preserves thread quality and protects mating components in assemblies; worn taps should be replaced to avoid damage to threaded parts.

FAQ

What sizes are included in the set?
The kit contains one tap each in M3, M4, M5, M6, M8, M10 and M12, supplied as a 7‑piece set (SKU 2000867745NW).

Which materials can be machined with these taps?
The taps are suitable for machining steel, stainless steel, spheroidal cast iron and non‑ferrous metals, owing to the HSS‑Co cutting material and universal geometry.

Is this set suitable for machine tapping?
Yes, the set is a machine‑grade tap set designed for use in tapping machines; correct feed and lubrication are recommended for best tool life.

What benefit does the vapour coating provide?
The vapour‑coated finish reduces friction and improves chip flow, resulting in lower wear and more consistent thread quality during repetitive production.

How does the tolerance ISO2 (6H) affect assembly fit?
Tolerance ISO2 (6H) ensures a standardised internal thread fit that is compatible with ISO external thread classes, providing predictable assembly behaviour and interchangeability.
