Machine tap DIN 371B Universal M8 x 1.25 – HSS‑Co PM, HARDLUBE, 2xD (TECWERK)

The Machine tap DIN 371B Universal M8 x 1.25 HSS‑Co PM HARDLUBE, 2xD is a straight‑flute metric tap designed for through threads and universal use in a wide range of engineering materials.

• Powder‑metallurgy HSS‑Co grade for high wear resistance
• HARDLUBE coating reduces friction and build‑up
• Straight‑flute, Form B, DIN 371 2xD design
• Tolerance 6HX for ISO metric threads

High‑performance threading for mixed materials

The tap combines powder‑metallurgy HSS‑Co (cobalt alloy) with a HARDLUBE surface to deliver improved wear resistance and reduced friction during cutting. This metallurgical choice raises hardness retention at temperature and extends service intervals, which directly lowers tool change cost and machine downtime. The M8 x 1.25 metric profile is produced to DIN 13 sheet 1 with 6HX tolerance, offering reproducible, factory‑conforming threads suitable for assembly and repair work. For production planners, the result is predictable cycle times and fewer rejects.

Reduced friction for clean, repeatable threads

The HARDLUBE coating lowers adhesion and chip sticking, while the optimised edge rounding and cutting geometry promote a smooth chip flow. The tool’s chamfer for through threads (peel chamfer) enables clean entry and exit on through holes, preventing thread distortion and minimising rework. The combination of coating and geometry reduces torque peaks and helps maintain tap straightness, which is especially beneficial when threading stainless steels and other sticky alloys; the result is consistent thread form and a lower scrap rate.

Practical compatibility and workshop handling

Designed with a straight‑flute (Form B) geometry and a shank diameter of 8 mm, the tap fits standard holders and is simple to clamp securely. The tool length conforms to DIN 371, enabling predictable reach in fixtures and bores. Right‑hand cutting direction and the 2xD working length make it suitable for general workshop use, maintenance tasks and batch production where a combination of versatility and reliability is required. The tool’s universal application across steel, stainless steel, aluminium and copper alloys and castings makes it a practical choice for mixed‑material environments, reducing the need for multiple special‑purpose taps.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap is suitable for steel, stainless steel, aluminium and copper alloys as well as castings, owing to its HSS‑Co PM substrate and coating.

What does the 6HX tolerance mean for assembly?
A 6HX tolerance specifies the thread pitch diameter limits for metric ISO threads; taps produced to this tolerance provide good general‑purpose fit for standard fasteners.

Is the tap suitable for through holes only?
The tool features a peel chamfer for through threads, optimising it for through holes, while the 2×D length still allows safe use in many blind‑hole applications with appropriate pecking or coolant strategies.

How should the tap be clamped and driven?
Use a rigid, concentric holder compatible with an 8 mm shank and apply a steady feed and appropriate lubrication; the straight‑flute geometry supports controlled chip evacuation in most general applications.

What benefits does the HARDLUBE coating provide?
HARDLUBE reduces friction and adhesion, which decreases torque, improves surface finish and extends tool life—particularly beneficial when threading stainless steels and other adhesive materials.
