Machine tap DIN 371C Universal M3 x 0.5 — HSS‑Co PM, HARDLUBE (TECWERK)

The machine tap DIN 371C M3 x 0.5 HSS‑Co PM, HARDLUBE is a universal right‑hand spiral tap designed for blind holes in a wide range of metals, offering reliable dimensional control for production environments

• HSS‑Co PM for high wear resistance
• HARDLUBE coating for reduced friction
• Form C (DIN 371) — 2×D shank length
• Right‑hand 40° spiral for blind holes

Engineered for dependable production threading

The tool combines powder metallurgy HSS‑Co (HSS‑Co PM) with a HARDLUBE surface treatment to extend tool life and reduce seizing under moderate to heavy use. Powder metallurgy results in a more uniform carbide distribution, which improves toughness and wear resistance compared with conventional high‑speed steels. The result is a tap that maintains thread quality over longer production runs, reducing stoppages and rework while supporting consistent thread profiles to metric ISO tolerances.

Broad material compatibility reduces tooling complexity

Designed as a universal solution, the tap is suitable for machining threads in steel, stainless steel, aluminium and copper alloys, and castings, with geometry optimised to handle chip formation across these substrates. The combination of tool steel and coating helps manage heat and adhesion when cutting softer non‑ferrous alloys as well as tougher stainless grades. For shops that run mixed batches, this reduces the need for multiple dedicated taps and simplifies inventory management.

Geometry and coating explained for practical benefits

Form C in accordance with DIN 371 and a nominal cutting length of 2×D make the tool suitable for standard machine tapping operations, while the right‑hand 40° spiral favours blind‑hole applications by directing chips back out of the cut. The tap is produced to tolerance field 6HX for metric ISO threads, ensuring interchangeability and correct fit with mating parts. The HARDLUBE coating lowers friction, which translates into lower spindle load, improved surface finish and reduced tendency for chip welding on the cutting edges.

Practical workshop integration and handling

With a shank diameter of 3.5 mm and a DIN 371 build, the tap fits common machine holders and collets used in production environments. The universal cut and optimised edge rounding reduce the need for finishing passes in many assemblies, saving cycle time. For machine set‑up, the tool’s robust build supports stable feed rates and speeds appropriate for the listed materials; tool life extension and process reliability contribute to predictable maintenance cycles and fewer unscheduled tool changes.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap DIN 371C M3 x 0.5 HSS‑Co PM, HARDLUBE is specified for steel, stainless steel, aluminium and copper alloys and castings, covering most common workshop substrates.

Is the tap suitable for blind‑hole threading?
Yes, the tool geometry and the right‑hand 40° spiral are optimised for blind holes; the product’s designation and construction indicate suitability for sacklochgewinde.

What does HSS‑Co PM mean for tool life?
HSS‑Co PM denotes powder metallurgy cobalt high‑speed steel; this produces a tougher, more wear‑resistant substrate so the TECWERK tap maintains edge integrity and extends service life under typical production conditions.

How does the HARDLUBE coating help in practice?
The HARDLUBE coating on the tap reduces friction and adhesion at the cutting zone, which lowers spindle load, improves surface finish and decreases the risk of chip welding on the cutting edges when producing the M3 x 0.5 thread.

Which tolerance class and standard does the thread conform to?
The tap is manufactured to DIN 371 Form C with tolerance field 6HX for metric ISO threads, providing compatibility with standard mating parts.
