Machine thread tap bit HSSE 9 M12×10.20 mm, pitch 1.75 mm — VÖLKEL, 6.3 mm hex shank

A VÖLKEL machine tap bit designed for forming metric ISO threads in blind holes, optimised for general workshop and CNC applications in unalloyed and low-alloy steels.

• HSSE cobalt for enhanced wear resistance
• Form C 15° RSP geometry
• 6.3 mm (1/4") hex shank for machine use
• Suitable for blind hole threads up to 900 N/mm²

Consistent blind-hole threading with minimal rework

The HSSE composition ensures wear resistance and temperature stability during interrupted cuts, which translates into fewer tool changes and more productive machine hours. Combined with the Form C (15° RSP) flute geometry, the tool evacuates chips reliably from blind holes, reducing the risk of chip packing and rework. This results in more consistent thread quality and repeatable threads in production batches, particularly when processing unalloyed or low-alloy steels up to 900 N/mm².

Accurate fit and compatibility with standard toolholders

Designed for metric ISO threads with ISO2 (6H) tolerance, the bit supports precise assembly fit tolerated by most engineering applications. The 6.3 mm (1/4") hex shank provides secure engagement in chucks and quick-change adapters, reducing setup time on both manual drilling rigs and CNC tapping heads. Compliance with WN (DIN 376) and the defined thread geometry helps maintain interchangeability across fixtures and mating parts, simplifying quality assurance and inventory planning.

Durable geometry that supports workshop efficiency

The tool length of 110 mm and compact profile make it suitable for restricted access and deep blind-hole tapping where clearance is limited. The HSSE material and the selected flute form extend tool life under typical shop conditions, lowering per-thread costs and downtime. For production environments seeking to optimise throughput, the bit’s balance of durability and chip control supports steady, high-quality output with reduced scrap rates.
