TECWERK Machine Tap DIN 371C H M4 x 0.7 mm HSS‑Co (6H) — Form C, right‑hand spiral 40°

TECWERK M4 x 0.7 mm machine tap for metric ISO threads, designed for blind‑hole applications and high‑strength steels

HSS‑Co for high-strength steels
Right-hand spiral 40° for chip evacuation
DIN 371C Form C with ISO2 (6H) tolerance
Designed for blind-hole metric threads

Predictable thread quality for demanding assemblies

The combination of DIN 371C Form C geometry and the ISO2 (6H) tolerance band ensures consistently accurate thread profiles that mate reliably with standard fasteners. This results in fewer rejected parts and reduced rework in series production. The specification to DIN 13 Blatt 1 clarifies the metric thread form and pitch, making integration straightforward for engineering and quality control teams seeking reproducible results.

Improved machining process through optimised chip control

A right‑hand spiral 40° and flank‑ground cutting edges promote controlled chip flow away from the cutting zone, which is crucial when producing blind‑hole threads. The spiral geometry reduces the risk of chip packing and premature tool breakage, enhancing process stability and lowering downtime between tool changes. For production environments, this means more continuous cycles and fewer interruptions on automatic tapping units.

Durable cutting performance for hard-to-machine materials

Forged from HSS‑Co (cobalt high‑speed steel), this tap is specified for use in steels with strengths >1000 N/mm², providing thermal stability and wear resistance under elevated cutting stresses. The material choice affords longer life compared with conventional high‑speed steels when tackling alloyed and high‑strength steels, contributing to a better overall cost‑per‑part in medium to large batch runs.

Machine‑compatible design for efficient setup and repeatability

A 4.5 mm shank diameter suits many common tapping adapters and collet chucks, simplifying installation on CNC machines or tapping heads. The tool’s Form C, Type H geometry facilitates smooth entry and reliable thread formation in pre‑drilled blind holes, supporting automated workflows. Production planners and workshop managers benefit from a tool that combines straightforward mounting with predictable tool life, aiding in capacity planning and inventory management.
