Machine tap DIN 371 C — M2.5 x 0.45 mm, HSS‑Co PM, HARDLUBE (TECWERK)

The Machine tap DIN 371 C M2.5 x 0.45 mm is a universal, machine‑grade tapping tool designed for blind threads and mixed‑material production in workshop and industrial environments.

• HSS‑Co PM for hard‑wearing performance
• HARDLUBE coating reduces friction
• Metric ISO thread to DIN 13, tolerance 6HX
• Suitable for blind holes and mixed materials

High‑performance threading across common workshop materials

The HSS‑Co PM substrate (powder‑metallurgy high‑speed steel with cobalt) delivers a marked improvement in wear resistance and toughness compared with conventional HSS, enabling longer tool life under repetitive machine tapping. Combined with the HARDLUBE surface treatment, friction and heat generation are reduced, which supports higher productivity and fewer tool changes. The right‑hand spiral 40° geometry promotes controlled chip formation and evacuation, an important advantage when producing blind holes to prevent chip packing and improve thread integrity.

Consistent metric threads to industrial standards

Designed for production of M2.5 x 0.45 mm metric ISO threads, the tool conforms to DIN 13 (part 1) with a tolerance of 6HX, ensuring interchangeability and predictable fit in assemblies. The Form C geometry and DIN 371 length specification provide a balance between entry control and flute length for a reliable thread profile. For applications where dimensional consistency and repeatability are critical, this specification reduces rework and facilitates downstream assembly operations.

Universal design that reduces inventory and simplifies machining

As a universal type with a DIN 371 build and a shank diameter of 2.8 mm, the tap suits a broad range of machine tapping setups and reduces the variety of tools needed at the workbench. The optimised edge rounding and cutting geometry lower insertion torque and improve surface finish, making the tool appropriate for steel, stainless steel, aluminium and copper alloys, as well as cast iron. The 2xD nominal length supports common blind‑hole depths while retaining rigidity for controlled threading under power feeds.

FAQ

What materials is the tap suitable for?
The TECWERK machine tap is suitable for steel, stainless steel, aluminium and copper alloys, as well as cast iron, making it versatile for mixed‑material production.

Is this tap suitable for blind holes?
Yes — the tool is specified for blind‑hole threading and the right‑hand spiral 40° aids chip evacuation to reduce the risk of chip jamming in blind threads.

What does the 6HX tolerance mean for assembly?
A 6HX tolerance on the produced internal thread provides a controlled fit according to DIN 13, ensuring consistent assembly performance and interchangeability with standard fasteners.

Which coating and substrate improve tool life?
The combination of HARDLUBE coating and HSS‑Co PM substrate increases wear resistance and reduces friction, extending tool life under repetitive machine tapping.

What length and shank dimensions does the tap have?
The tap follows DIN 371 nominal length (2xD) with a shank diameter of 2.8 mm, suitable for common machine tapping fixtures.
