Machine tap DIN 371C H M6×1 HSS‑Co 6H by TECWERK — high‑performance metric tap for demanding materials

The Machine tap DIN 371C H M6×1 HSS‑Co 6H is a robust metric machine tap designed for producing precise blind ISO threads in hard or difficult‑to‑cut steels, offering industrial reliability and standardised tolerances

• HSS‑Co for improved heat resistance and wear
• Form C, Type H — optimised flute and cutting geometry
• Right‑hand 40° helix for reliable chip evacuation
• Tolerance ISO2 (6H) for consistent metric threads

Consistent, standardised threads for industrial production

The tap is engineered to deliver repeatable M6×1 threads to DIN 13 Sheet 1 tolerances, reducing rework and scrap in series production. The tolerance ISO2 (6H) specification ensures compatibility with widely used mating parts and assembly processes, which simplifies inspection and quality control. Using a tool built to industrial standards removes ambiguity in procurement and supports streamlined production planning. The focus is on measurable, verifiable results rather than subjective claims.

Material and cutting performance for tough steels

Manufactured from HSS‑Co, the cutting material combines high‑speed steel with cobalt alloying for elevated hot hardness and resistance to abrasion. This makes the tap suitable for hard‑to‑machine steels >1000 N/mm², where ordinary high‑speed taps would wear prematurely. The cobalt content improves edge stability at higher cutting temperatures, meaning longer tool life under demanding cycle conditions and fewer interruptions for tool changes — a direct gain in uptime and cost efficiency.

Geometry that controls chips and protects thread flanks

The right‑hand 40° helix together with Form C, Type H geometry promotes controlled chip formation and evacuation, which is especially important when working with blind holes. The tool’s flank relief reduces friction on the thread flanks, producing cleaner thread profiles and reducing the risk of galling. For blind‑hole tapping the design minimises chip packing at the flute ends, lowering breakage risk and improving process reliability compared with standard straight‑flute taps.

Practical fit‑and‑forget performance at the machine

With a shank Ø 6 mm, the tap integrates easily into standard machine holders and tapping spindles, supporting automatic and semi‑automatic tapping operations. The tool is optimised for use as a machine tap (DIN 371C), enabling fast cycle times while preserving thread quality. Maintenance is straightforward: periodic inspection and regrinding according to shop practice extend service life. The industrial‑grade construction translates into fewer production stops and predictable output for workshop and manufacturing environments.

FAQ

What materials is this tap suitable for? The TECWERK machine tap (Machine tap DIN 371C H M6×1 HSS‑Co 6H) is designed for hard‑to‑machine steels and other demanding materials; the HSS‑Co composition gives improved wear resistance when machining steels above 1000 N/mm².

Can this tap be used for blind holes and through holes? Yes. The tool’s geometry, including the 40° helix and flank relief, is optimised for blind holes, reducing chip packing; it is also compatible with through‑hole applications when required.

What tolerance and thread standard does the tap produce? Threads are produced to DIN 13 Sheet 1 with tolerance ISO2 (6H) for reliable interchangeability with standard metric components.

What shank size is required for machine mounting? The tap has a shank Ø 6 mm, suitable for common machine holders and automatic tapping spindles used in production environments.

How does the HSS‑Co material benefit production runs? The HSS‑Co alloy maintains hardness at elevated cutting temperatures, extending tool life and reducing unplanned tool changes during continuous machining operations.
