TECWERK machine tap DIN 376B VA M20×2.5 HSS‑Co TiCN (6H)

The TECWERK machine tap DIN 376B VA M20×2.5 is a metric machine-thread tap for industrial production, engineered for stainless, acid- and heat-resistant steels and suited to standard machine holders.

• HSS‑Co substrate with TiCN coating
• Straight flutes and flank-ground geometry
• For stainless and heat-resistant steels up to 1000 N/mm²
• ISO2 (6H) tolerance to DIN 13

High-performance threading for demanding alloys

This machine tap combines a HSS‑Co base material with a TiCN (titanium carbonitride) surface layer to reduce friction and resist built-up edge formation when cutting stainless and similar alloys. The coating lowers adhesion between chip and tool, which extends service intervals and maintains a consistent cutting geometry during production runs. When machining materials with tensile strengths up to 1000 N/mm², the coated high-speed steel core provides a balance of toughness and wear resistance that is particularly useful for continuous or automated tapping operations.

Precision fit and dependable thread quality

Designed to DIN 376B in Form B and to produce metric ISO threads, the tap meets the ISO2 (6H) internal tolerance class for reliable assembly fits. The straight-flute design, together with flank-ground geometry, promotes controlled chip formation and improved surface finish in the threaded bore. With a shank Ø 16 mm, the tool fits common collet and holder systems on machining centres and tapping spindles, while the through-thread chamfer (Schälanschnitt) facilitates clean starts and consistent thread profiles for through holes.

Practical advantages for workshop and production environments

The construction and features of this tap reduce downtime and rework: longer tool life from the TiCN coating decreases frequency of tool changes, and the flow-friendly flute geometry lowers breakage risk in high-volume use. Traceable conformity to DIN 13 Blatt 1 and a consistent tolerance class support quality assurance procedures in industrial settings. For workshops seeking dependable threading performance paired with straightforward integration into existing tool inventories, this tap offers a pragmatic, production-ready solution.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is designed for stainless, acid- and heat-resistant steels and is rated for materials up to roughly 1000 N/mm² tensile strength.

What advantage does the TiCN coating provide?
TiCN on the HSS‑Co substrate reduces friction and adhesive wear, improving tool life and maintaining thread quality under continuous production loads.

Which tolerance and standard does the tap comply with?
The tool conforms to DIN 376B and produces metric threads to DIN 13 Blatt 1 with an internal tolerance of ISO2 (6H) for consistent fit and assembly.

Is the shank compatible with standard machine holders?
With a shank diameter of 16 mm, the tap is compatible with common collet systems and machine tool holders used for tapping operations.

What is the chamfer type and its benefit?
The tap features a through-thread chamfer that eases entry into through holes and supports reliable chip formation and clean thread starts.
