M20x2.5mm Machine Tap DIN 376B AL HSS-Co 6H Straight Flute Scalloped Shank, ISO2 Tolerance - TECWERK

The combination of cobalt-alloy high-speed steel, a shearing cut for through-threads and DIN/ISO conformity ensures reliable, repeatable thread production in long‑chip, soft materials; order the TECWERK machine thread tap directly via Metav Werkzeuge or contact the consultants for application advice.

Machine thread tap DIN 376B AL M20x2.5 HSS‑Co 6H — TECWERK, straight‑fluted, precision tolerance

The Machine thread tap DIN 376B AL M20x2.5 HSS‑Co 6H is a straight‑fluted, Form B tapping tool designed for producing metric ISO through‑threads in long‑chip, soft materials on machine tapping stations.

• Cobalt HSS for improved wear resistance
• Straight flutes with relief‑ground flanks
• ISO metric thread DIN 13, tolerance ISO2 (6H)
• Shearing cut for reliable through‑threading

Precision threads that ensure interchangeability and fit

Built to the DIN 376B standard and delivering metric ISO threads with the ISO2 (6H) tolerance field, this tap provides consistent thread geometry for components that require reliable mating and repeatable assembly. The tool’s adherence to established norms reduces fitting issues and rework, which directly benefits production yield. The tolerance specification supports interchangeability across batches and suppliers, making the tap suitable for regulated production environments where traceability and conformity are essential.

Cutting geometry engineered for chip control and surface quality

The combination of HSS‑Co material and a shearing cut produces controlled chip formation when machining long‑chip, soft materials. The straight flutes assist chip evacuation in through‑holes, while the flanks being relief‑ground lowers friction and improves surface finish of the internal thread. Together these features prolong tool life and reduce machine downtime by minimising chip jamming and lowering the need for frequent tool changes, a clear advantage in continuous or batch production.

Compatibility with machine tapping and straightforward integration

Specified as Form B, type AL, the design suits machine tapping applications, offering dependable engagement and stable cutting action. The tap’s metric designation M20 x 2.5 and standardised form allow easy integration into existing tool setups and process plans. The shank diameter and overall geometry support secure clamping in common machine spindles and tapping heads, facilitating rapid changeovers and predictable cycle times for production schedules.

Robustness, handling and workshop efficiency

Manufactured from a cobalt‑alloy high‑speed steel mix, the tool balances toughness with heat resistance, helping maintain cutting edges under demanding cutting conditions. The straight‑fluted profile with relief‑ground flanks simplifies reconditioning compared with more complex geometries, while the solid construction contributes to consistent axial alignment and reduced thread runout. For workshops looking to rationalise suppliers, this tap supports a cost‑effective approach by lowering scrap and increasing first‑pass success rates.

FAQ

What materials is this tap intended for? The TECWERK machine thread tap is designed specifically for long‑chip, soft materials where its shearing cut and straight flutes provide reliable chip control and surface quality.

Does the tap conform to recognised standards for interchangeability? Yes, the tap produces metric ISO threads to DIN 13 Sheet 1 and meets the ISO2 (6H) tolerance field for consistent fit and interchangeability.

What are the key benefits of the HSS‑Co material in this tap? HSS‑Co offers improved wear resistance and heat tolerance compared with standard HSS, so the TECWERK tap maintains cutting performance longer under demanding machine conditions.

What shank size is required for mounting this tap? The tool features a shank diameter of 16 mm, compatible with common machine tapping chucks and holders used in production environments.

Is this tap suitable for through‑threads only? The tap is equipped with a shearing cut for through‑threads, optimised for such applications; use in blind holes would require process assessment and potentially different tap geometry.
