Machine tap bit set DIN 371/376 Form B – metric HSS‑Co by VÖLKEL GmbH with HexDrive 6.3 mm (1/4") shank

The Machine tap bit set DIN 371/376 Form B – metric HSS‑Co is a compact 7-piece kit designed for standardised ISO metric threads in production and workshop environments

• Cobalt HSS for enhanced wear resistance
• 1/4" HexDrive shank for rapid tool changes
• Metric ISO threads covering M3–M12
• Supplied in compact plastic case

Consistent thread quality for production and maintenance

The set combines HSS‑Co cutting composition with the DIN 371 and DIN 376 geometries to deliver stable thread form and reduced breakage risk. This composition — commonly described as cobalt high-speed steel — increases red-hardness and wear resistance, which prolongs tool life when cutting metric ISO threads. For everyday assembly and repair tasks, the precision-ground flutes and standardised shank ensure repeatable results and lower scrap rates.

Faster workflow with a standard HexDrive and neat storage

Equipped with a HexDrive 6.3 mm (1/4") shank, the taps plug straight into standard bit holders and quick-change adapters, reducing dwell time at the machine or cordless driver. The 7-piece assortment covering M3–M12 removes the need to swap between multiple tool sets for common thread sizes. Delivered in a robust plastic case, the kit keeps tools organised and protected, which speeds up retrieval and supports efficient workstation management.

Material compatibility and predictable tool life

This kit is specified for machining unalloyed and low-alloy steels with tensile strengths up to 900 N/mm², offering a clear indication of suitable workpieces. The cobalt-enriched substrate helps resist wear in intermittent cutting and higher-temperature conditions, making the set appropriate for maintenance, fabrication, and light production work. Using the correct lubricant and recommended spindle speeds further extends service intervals and improves chip evacuation for cleaner threads.
