VÖLKEL Machine Tap Bit HSSE 6 M5 x 4.20 mm, pitch 0.80 mm — HSS‑Co, 6.3 mm (1/4") hex shank

A VÖLKEL Machine Tap Bit HSSE 6 M5 x 4.20 mm designed for consistent production of metric M5 threads in readily machinable steels and low‑alloy materials.

• HSS‑Co cutting material for elevated wear resistance
• 6.3 mm (1/4") hex shank for secure machine holding
• Metric M5, pitch 0.80 mm, ISO2 (6H) tolerance

Consistent thread quality for production runs

The HSSE construction provides higher hot hardness and improved wear resistance compared with standard grades, which directly translates into longer tool life and fewer tool changes during batch production. Combined with the ISO2 (6H) tolerance, the tool produces threads that meet common metric standards, reducing fitment errors and post‑machining adjustments. This reliability is particularly valuable where interchangeability and repeatability are essential.

Optimised for machine tapping and quick changes

Equipped with a 6.3 mm (1/4") hex shank and configured as Form B to DIN 371, this tap bit fits many machine holders and quick‑change chucks used in automated machining cells. The compact 70 mm length keeps overhang minimal, improving rigidity and reducing chatter. The hex shank accelerates tool changes and minimises setup time, which enhances throughput without compromising thread quality.

Efficient chip control and through‑thread performance

The integrated countersink cut for through holes encourages reliable chip formation and evacuation, lowering the risk of chip jamming and breakage in continuous machining processes. For applications in unalloyed and low‑alloy steels up to 900 N/mm², the tool delivers clean thread flanks and consistent lead, helping to shorten cycle times and reduce scrap rates. The pitch 0.80 mm ensures accurate thread geometry for standard M5 assemblies.

Practical benefits for workshop and production planning

Conforming to DIN 371 and carrying a metric ISO thread form simplifies quality assurance and incoming inspection routines. The robust HSS‑Co material, together with the production‑oriented geometry, produces a favourable cost‑to‑performance ratio across medium to high quantities. Maintenance effort is reduced thanks to longer intervals between regrinds, while machine operators benefit from dependable behaviour under typical shop conditions.
