Machine tap bit HSSE 3.5 M3 x 0.50 mm, VÖLKEL — HSS‑Co machine tap bit with HexDrive shank

Machine tap bit HSSE 3.5 M3 x 0.50 mm, VÖLKEL is a robust HSS‑Co tap designed for forming precise ISO metric threads in unalloyed and low‑alloy steels up to 900 N/mm², intended for use with power drivers and tapping heads

• HSS‑Co cutting material for higher wear resistance
• 6.3 mm (1/4") HexDrive shank for rapid tool changes
• Form B geometry, WN (DIN 371) standard compliant
• ISO2 (6H) tolerance for accurate metric threads

Reliable thread quality for production environments

The HSS‑Co construction ensures improved heat resistance and longer tool life compared with standard high‑speed steel, which translates into more consistent thread quality over longer runs. The built‑in ISO2 (6H) tolerance and metric M3 x 0.50 mm geometry deliver repeatable fits that meet assembly specifications, while the Form B design follows the WN (DIN 371) standard to guarantee compatibility with established machining processes. These technical properties reduce rejects and rework, supporting a smoother production flow and predictable maintenance intervals.

Fast changeover and machine compatibility

Equipped with a 6.3 mm (1/4") HexDrive shank, this bit is optimised for direct use in power drivers, quick‑change adaptors and tapping machines, enabling rapid tool changes and minimising downtime between operations. The integrated peel‑cut geometry for through threads improves chip evacuation during tapping, lowering the risk of thread damage in continuous or automated workflows. As a result, cycle times are shortened and operational efficiency is increased without compromising thread integrity.

Application range and material performance

Designed for general use in readily machinable materials, the tool is suitable for unalloyed and low‑alloy steels up to 900 N/mm², making it a practical choice for routine production and maintenance tasks. The HSSE cutting material supports higher cutting speeds and tougher conditions than standard HSS, while the tap’s overall length of 56 mm provides a balanced engagement for standard thread depths. For shops that handle mixed batches, this combination of material compatibility and geometry reduces the need for frequent tool changes.

Standards, tolerances and practical advantages

Conformance with DIN 371 (WN) and the adoption of Form B geometry mean the tool integrates seamlessly into existing tool sets and machining programmes. The specified tolerance class ISO2 (6H) ensures that nuts and mating parts maintain the desired clearance and strength without additional hand‑fitting. Together, these attributes make the bit a dependable component for consistent, quality threads across batches and shift patterns, thereby supporting predictable assembly performance.

FAQ

What materials is this tap bit suitable for?
The VÖLKEL machine tap bit is intended for unalloyed and low‑alloy steels and is specified for use up to 900 N/mm², making it suitable for common structural and component steels.

Can the bit be used with power drivers or tapping heads?
Yes. The 6.3 mm (1/4") HexDrive shank allows safe and fast installation in power drivers, quick‑change adaptors and automated tapping heads.

Which standards and tolerances does the tool meet?
The tool conforms to WN (DIN 371) and delivers metric threads to the ISO2 (6H) tolerance class for reliable mating fits.

How does HSSE benefit the tapping process?
The HSSE (HSS‑Co) cutting material increases heat resistance and wear life compared with standard HSS, giving longer service life and more consistent thread quality under higher cutting speeds.

What is the functional length and application type of the tap?
The overall length is 56 mm and the geometry is optimised for through threads with a peel cut to aid chip evacuation during continuous tapping.
