Maschinengewindebohrer DIN 371C AL M8x1,25mm HSS‑Co 6H – TECWERK machine tap, Form C, Type AL, right‑hand spiral

Maschinengewindebohrer DIN 371C AL M8x1,25mm HSS‑Co 6H is a high‑performance machine tap designed for efficient production of metric ISO threads in blind holes, optimised for long‑chipping, soft materials.

• HSS‑Co construction for wear resistance
• Right‑hand spiral 45° for reliable chip evacuation
• Tolerance field ISO2 (6H) for accurate thread fit
• Shank Ø 8 mm for secure machine holding

Consistent blind‑hole threading with improved productivity

The combination of HSS‑Co material and a right‑hand spiral 45° design ensures reliable chip control when producing blind‑hole threads. The cobalt‑alloyed high‑speed steel provides higher hot‑hardness and abrasion resistance than standard high‑speed grades, which translates into longer life in serial machining. The spiral‑flute geometry actively guides chips away from the cutting face, reducing the risk of clogging in blind holes and maintaining a stable cutting process — a direct benefit for workshops and production lines aiming to reduce downtime and rework.

Precise fits and standard‑compliant threads for assembly reliability

Manufactured to DIN 371 C and forming metric ISO threads (DIN 13‑1) with tolerance ISO2 (6H), this tap produces threads that meet industry standards for interchangeability and assembly. The form C / type AL specification and the flank relief (flank undercutting) yield consistent dimensional accuracy and improved thread runout, making the component joints predictable and reliable. For engineering teams focused on repeatable quality and minimal adjustment during assembly, the standardised tolerance class secures a dependable fit with mating parts.

Robust design for machine‑shop integration and operational ease

With a shank Ø 8 mm the tap is compatible with most machine holders and tapping spindles used in CNC and automatic tapping heads. The flanks hinterschliffen (flank relief) and gelbring geometry support controlled chip formation in long‑chipping, soft materials, reducing the chance of chip entanglement. These features lower the need for frequent tool changes and help maintain throughput in production environments. For procurement and shop managers, the combination of durable material, chip‑directing spiral and machine‑ready shank simplifies tool inventory and process planning.

FAQ

What thread size does this tap produce?
The TECWERK machine tap produces an M8 × 1.25 mm metric ISO thread suitable for standardised assemblies.

Is the tap suitable for blind holes?
Yes, the tool is specified for blind‑hole threading and features a right‑hand spiral 45° to aid chip evacuation in blind holes.

What material is the tap made from and why does that matter?
The tap is manufactured from HSS‑Co (cobalt high‑speed steel); this increases hot‑hardness and wear resistance, extending life under cyclic and heavy machining.

Which tolerance and standard does the tap meet?
Threads comply with DIN 371 C and DIN 13‑1, produced to ISO2 (6H) tolerance for a precise and repeatable fit.

Can this tap be used in CNC tapping spindles?
Yes, the shank Ø 8 mm makes the tool compatible with common machine holders and tapping spindles used in automated operations.
