Machine Tap DIN 376B VA M20 x 2.5 HSS‑Co, nitrided & vapour‑deposited — TECWERK

A Machine Tap DIN 376B VA M20 x 2.5 for production threading of metric ISO threads in stainless, acid‑ and heat‑resistant steels

• HSS‑Co substrate for high wear resistance
• Nitride and vapour‑deposited coating for longevity
• Straight flutes with flank relief for stable chips
• ISO2 (6H) tolerance for precise thread fit

Precision threading for high‑strength stainless steels

The Machine Tap DIN 376B VA M20 x 2.5 combines a HSS‑Co cutting material and an optimised geometry to deliver consistently accurate threads in demanding alloys. The tool conforms to DIN 376B and is intended for metric ISO threads with ISO2 (6H) tolerance, which ensures interchangeability and reliable assembly. The reduced chamfer is configured as a cutting chamfer for through threads, limiting axial force peak and facilitating uninterrupted production runs. This technical setup reduces scrap rates and supports stable process capability in series manufacturing.

Longer tool life through surface engineering and geometry

An advanced surface treatment — nitride plus vapour‑deposited coating — increases hardness and abrasion resistance at the cutting edge while preserving edge toughness. The straight‑flute design, with flanks relief ground, promotes predictable chip formation and evacuation in through‑hole tapping, which in turn reduces galling on stainless materials. Together, these features lower downtime for tool changes and deliver an improved cost‑per‑thread in medium to high‑volume environments, backed by measurable wear resistance under elevated tensile conditions.

Machine readiness and handling benefits for production use

Designed with a shaft Ø 16 mm, the tap provides secure clamping and reduced run‑out in machine tool spindles. The tool’s Form B profile and blue ring identification simplify tool selection on busy production floors. Compatibility with steels of tensile strength >850 N/mm² is specified for reliable cutting performance in tough alloys. Operators benefit from a tool that is straightforward to integrate: the geometry minimises torque spikes and contributes to stable cycle times, key for efficient process planning and predictable throughput.

FAQ

What thread standard does this tap produce?
The tap produces metric ISO threads to DIN 376B, manufactured to an ISO2 (6H) tolerance for standardised mating.

Which materials is the tap designed to machine?
This TECWERK tap is specified for stainless, acid‑ and heat‑resistant steels, suitable for materials with tensile strength over 850 N/mm².

What is the shank size and why does it matter?
The tool has a shaft Ø 16 mm, which provides secure clamping and reduced run‑out for improved thread accuracy.

How does the coating affect tool life?
The combination of nitride and a vapour‑deposited coating increases surface hardness and wear resistance, extending service life under production conditions.

Is this tap suitable for through‑hole threading?
Yes, the tap features a cutting chamfer optimised for through threads to support efficient chip evacuation and consistent thread form.
