TECWERK M5×0.8 Machine Tap DIN 371C AL – HSS‑Co, 6H tolerance

The M5×0.8 Machine Tap DIN 371C AL is intended for producing metric ISO blind threads in long-chip, soft materials, offering a 45° right-hand spiral and relieved flank geometry for reliable chip control.

• HSS‑cobalt construction for heat resistance
• Right‑hand 45° spiral for blind‑hole evacuation
• ISO metric M5×0.8 with ISO2 (6H) tolerance
• 6 mm shank for secure machine clamping

Consistent performance through high‑alloy cutting material

Made from HSS‑Co, this tool delivers elevated hot hardness and improved wear resistance compared with standard high‑speed steels, which supports longer tool life under interrupted cuts and elevated temperatures. Conformity with DIN 371C and the DIN 13 Sheet 1 reference for metric threads ensures reproducible geometries, while the ISO2 (6H) tolerance field guarantees that assembled components will meet common industrial fit requirements. Those needing a robust solution for repetitive production runs will appreciate the stability that the cobalt alloy provides during sustained operation.

Geometry engineered for blind‑hole accuracy and chip control

The 45° right‑hand spiral and Form C / Type AL geometry are designed to favour chip transport back up the flute when working with long‑chip, soft materials; this reduces the risk of chip jamming in blind holes and improves surface finish of the tapped thread. Relieved flanks (flank ground) lower cutting forces and reduce thread friction, which aids entry and improves thread form in deep blind‑hole applications. The combination of spiral angle and flank relief makes the tool especially suitable for materials that tend to produce continuous swarf.

Machine compatibility and secure clamping for repeatable results

A 6 mm shank provides compatibility with common toolholders and ensures secure clamping for minimised run‑out and vibration. The tap’s specification for metric ISO thread M5×0.8 with ISO2 (6H) tolerance supports standardised assembly processes, while adherence to DIN 371C streamlines tooling selection for machines and holders already configured to that norm. For production environments, the predictable fit and repeatable thread form translate into reduced rework and higher first‑pass yield.

Practical advantages and supply reliability from a precision partner

Designed for manufacturers and workshops requiring dependable thread quality in series or single‑part production, this tap addresses the typical issues encountered when machining blind holes in long‑chip materials. Metav’s positioning as a precision partner brings added assurance: centralised stock in Emmerich, a broad catalogue that reduces supplier complexity and a track record of trusted supply. For complex or high‑volume projects, the technical profile of the tap — combined with Metav’s logistics and consultancy — supports stable procurement and process planning.

FAQ

What materials is the tap suitable for?
The tap is intended for long‑chip, soft materials; its HSS‑Co composition and spiral geometry favour aluminium‑type alloys and similar materials that produce continuous swarf.

Can the tap be used for blind‑hole tapping?
Yes. The combination of a 45° right‑hand spiral and relieved flanks is optimised for blind‑hole applications to improve chip evacuation and thread quality.

What does ISO2 (6H) tolerance mean for assembly?
The ISO2 (6H) tolerance field specifies the thread fit and ensures compatibility with standard metric mating parts, offering a reliable clearance for typical industrial assemblies.

Is the shank size compatible with standard holders?
The tap has a 6 mm shank, which is compatible with common machine tap holders and collets for secure clamping and reduced run‑out.

Which standard governs the thread form and profile?
The thread conforms to DIN 371C and refers to DIN 13 Sheet 1 for metric ISO thread form and profiling.
