M20x2.5mm Machine Tap DIN 376C HSS-Co Form C Right-Hand 45° Chip Groove 6H - TECWERK

Take advantage of the combination of HSS‑Co material, precise M20 x 2.5 metric threading and blind‑hole capability to secure consistent thread quality and minimise rework. Order the tap directly via Metav Werkzeuge or ask the consultants for application advice.

Machine tap DIN 376C Type AL M20 x 2.5 HSS‑Co (6H) – TECWERK

The machine tap DIN 376C Type AL M20 x 2.5 produces metric blind threads in long‑chip, soft materials and is designed for machine use with a 45° right‑hand spiral.

• HSS‑Co construction for improved heat resistance
• Type AL (Form C) geometry for blind hole tapping
• 45° right‑hand spiral with flank relief
• Shank Ø 16 mm for secure machine mounting

Consistent thread quality by material and tolerance

The combination of HSS‑Co alloy and the specified ISO2 (6H) tolerance field ensures durable cutting edges and predictable metric ISO thread accuracy. The cobalt‑alloyed high‑speed steel retains hardness at elevated temperatures, which reduces wear during longer runs and supports repeatable results. Because the tap is made for blind‑hole applications and conforms to DIN 13 Blatt 1, thread form and fit remain reliable across batches, lowering the risk of scrap or rework in series production.

Faster cycles and fewer interruptions thanks to geometry

The Type AL (Form C) geometry with a 45° spiral and flank relief is optimised for materials that produce long chips, improving chip evacuation and preventing clogging in blind holes. This chip control reduces cycle interruptions and the need for manual cleaning between cuts, which supports higher throughput in automated or CNC tapping operations. The design therefore translates directly into time savings and improved machine utilisation without sacrificing thread integrity.

Robust mounting and machine compatibility for reliable automation

A shank Ø 16 mm provides a solid connection to tapping heads and machine spindles, ensuring concentricity and transmitting torque efficiently. The tool is manufactured to DIN 376C dimensions for machine taps, which facilitates interchangeability and predictable set‑up in production workflows. Where precise, repeatable threads are required in softer, long‑chip materials, this machine tap offers a balance of durability, process stability and straightforward integration into existing tooling systems.

FAQ

Which materials are suitable for this machine tap?
The TECWERK machine tap is intended for long‑chip, softer materials; its Type AL geometry and 45° spiral promote safe chip formation and evacuation in these materials.

Is this tap suitable for blind holes?
Yes, the tool is designed specifically for blind‑hole threads and includes geometry and flank relief optimised to reduce chip jamming in closed‑end holes.

What benefits does HSS‑Co provide for tapping?
HSS‑Co offers increased hot hardness and wear resistance compared with conventional HSS, which extends tool life and maintains cutting performance during longer runs.

Does the tap meet standard thread tolerances for assembly use?
The tool is made to ISO2 (6H) tolerance and complies with DIN 13 Blatt 1, providing thread accuracy suitable for standardised assemblies.

What machine interfaces are compatible with this tap?
The 16 mm shank diameter is intended for secure mounting in machine spindles and tapping heads that accept DIN‑sized machine taps; the DIN 376C form supports easy integration.
