Machine tap bit HSSE M5×4.20 mm — HexDrive 1/4" shank, pitch 0.80 mm

A Machine tap bit HSSE M5×4.20 mm designed for metric ISO blind‑hole threads with a 0.80 mm pitch, suitable for general use in machinable materials up to 900 N/mm²

• HexDrive 6.3 mm (1/4") hex shank
• HSSE cutting material for longer life
• Form C 15° RSP for reliable chip control

Consistent precision for metric blind‑hole threads

The tool ensures accurate M5 thread generation with a 4.20 mm thread length and pitch 0.80 mm, meeting the requirements of DIN 371 (WN) and the ISO2 (6H) tolerance class. This degree of precision reduces fitment play in assemblies and cuts down on rework. The standard compliance and tolerance control provide repeatable results across production batches, supporting tight assembly tolerances and interchangeability.

Durable cutting performance in machinable steels

Manufactured from HSSE (high‑speed steel with cobalt), the bit brings enhanced hot‑hardness and wear resistance compared with standard HSS. It is specified for general application in unalloyed and low‑alloy steels and for materials up to 900 N/mm², offering extended service life under continuous use. The material choice lowers the frequency of tool changes, contributing to steadier production cycles and a higher overall equipment effectiveness (OEE).

Secure drive and effective chip management

The HexDrive 6.3 mm (1/4") shank allows positive engagement with machine holders and quick‑change systems, reducing slippage under torque. The Form C geometry with 15° RSP promotes controlled chip formation and evacuation, particularly important for blind‑hole tapping where chip clearance is restricted. The combination of shank security and flute design minimises the risk of breakage and supports uninterrupted machining in automated or semi‑automated setups.

Practical compatibility and workshop benefits

Conforming to metric ISO thread standards and recognised norms, the bit integrates easily into existing toolsets and tapping heads. The tool length of 70 mm is suitable for most machine tap holders while the ISO2 (6H) tolerance supports standardised mating with ISO threads. For shops seeking reliable production taps for small thread sizes, this solution balances precision, life, and machine‑compatibility without requiring specialised handling.
