Machine tap DIN 376B M20x2.5 HSS‑Co 6H by TECWERK — straight‑fluted, cobalt alloy for through threads

The Machine tap DIN 376B M20x2.5 HSS‑Co 6H TECWERK is a form B, straight‑fluted tap designed for producing metric ISO threads in through holes; suitable for machining steels up to approximately 900 N/mm².

• HSS‑Co cobalt alloy for extended tool life
• Form B straight flutes for through‑hole tapping
• ISO2 tolerance (6H) for high interchangeability
• 16 mm shank for standard machine holders

Accurate metric threads for consistent assembly

The combination of M20 x 2.5 thread geometry and the ISO2 (6H) tolerance class assures repeatable, high‑precision threads compatible with standard fasteners. The tool conforms to DIN 13 Blatt 1 and DIN 376B, which guarantees dimensional predictability and reduces the need for post‑process inspection. For production environments this means fewer rejects and consistent fit of mating parts; the standardized tolerance simplifies procurement of mating components and supports predictable assembly performance.

Robust cutting geometry for dependable performance

Constructed from HSS‑Co (cobalt‑alloy high‑speed steel) and produced in Form B with straight flutes, the tap offers improved heat resistance and wear performance compared with plain HSS. The flank relief (flanks ground) and the Schälanschnitt (peel cut) designed for through threads promote controlled chip formation and evacuation, lowering the risk of jamming and breakage. These features result in longer tool life and stable cycle times, which supports efficient production planning and reduces unplanned downtime.

Practical compatibility and workshop handling

A 16 mm shank provides secure clamping in standard toolholders and collets, enabling simple integration into existing machining centres and tapping heads. The tool is optimised for through‑hole tapping in steels up to approx. 900 N/mm² tensile strength, making it suitable for a wide range of general engineering applications. Clear marking and adherence to established standards make storage and tool selection straightforward, while the robust material and geometry reduce the frequency of replacements — a practical advantage for maintenance and purchasing departments.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is designed primarily for steels up to approximately 900 N/mm²; its HSS‑Co construction improves wear resistance for such applications.

Does the tap produce metric ISO threads and to which tolerance?
Yes, the tap produces metric ISO threads M20 x 2.5 and is manufactured to ISO2 (6H) tolerance for reliable interchangeability.

Is the shank compatible with standard toolholders?
The 16 mm shank is compatible with common collets and holders, allowing straightforward clamping in standard machining equipment.

What advantage does Form B straight flute provide?
Form B straight flutes are optimised for through‑hole tapping, providing predictable chip flow and reduced risk of chip clogging compared with spiral flute designs.
