Machine tap DIN 376B AL M12×1.75 HSS‑Co 6H (TECWERK) — straight‑fluted, shank Ø 9 mm

A machine tap DIN 376B AL M12×1.75 HSS‑Co 6H designed for efficient production of through threads in long‑chip, soft materials.

• HSS‑Co for enhanced wear resistance
• Straight flutes, flanks relieved for smooth cutting
• Special chamfer for through threads
• Shank Ø 9 mm for reliable machine mounting

Faster threading in long‑chip, soft materials

The cobalt‑alloy high‑speed steel (HSS‑Co) grade used in this machine tap delivers improved red hardness and wear resistance compared with standard high‑speed steels, which extends tool life under demanding production conditions. The geometry is optimised for long‑chip and soft materials, so the tool maintains cutting performance and reduces the frequency of tool changes. The result is higher throughput and fewer interruptions in automated or manual tapping operations.

Precise fit and standard conformity for dependable assembly

Manufactured to DIN 376B and referenced to DIN 13, the tap cuts an ISO metric thread M12×1.75 with the ISO2 (6H) tolerance field, ensuring interchangeability and predictable assembly behaviour. The defined tolerance reduces rework and simplifies inspection, so mating parts fit consistently in serial production. Clear standards compliance supports quality assurance and streamlines documentation for procurement and inspection processes.

Geometry and shank design for robust machine use

The Form B, type AL design combines straight flutes with relieved flanks to aid chip formation and evacuation, particularly in through‑hole applications. A reduced‑diameter shank Ø 9 mm provides secure clamping in standard tool holders or collets, improving concentricity and reducing run‑out. This geometry contributes to stable cutting forces and lower vibration, which benefits both surface finish and tool life during high‑volume tapping.

Clean through‑hole cuts and easy chip control

A dedicated shear chamfer for through threads promotes controlled chip departure and reduces the tendency to form long, stringy chips at the entry and exit of the hole. The shear chamfer works together with the straight‑flute geometry to direct chips away from the cutting edges, lowering the risk of thread damage and minimising machine stoppages. Combined with the cobalt alloy backbone, the tap is well suited to repeated cycles where consistent thread quality is required.

FAQ

Which materials is this tap suitable for?
The TECWERK machine tap is intended for long‑chip, soft materials, where its HSS‑Co composition and straight‑flute geometry provide reliable chip control and wear resistance.

Can this tap be used for through threads or blind holes?
This tool is optimised for through threads; the shear chamfer specifically assists chip evacuation in through‑hole applications and reduces thread damage at the exit.

What standards and tolerances does the tap meet?
The tap conforms to DIN 376B with reference to DIN 13, producing an M12×1.75 metric thread to the ISO2 (6H) tolerance field for consistent assembly fits.

What is the shank size and how is it mounted?
Shank diameter is 9 mm, allowing secure clamping in standard holders or collets for machine tapping operations and ensuring good concentricity.
