Take advantage of HSSE cutting performance, a quick-change 6.3 mm HexDrive shank and precise ISO2 (6H) tolerance for reliable machine tapping in general-purpose steels; order directly via Metav Werkzeuge or consult the team for specification support.

VÖLKEL Machine Tap Bit HSSE M4 x 3.30 mm, 6.3 mm (1/4") HexDrive

The VÖLKEL Machine Tap Bit HSSE M4 x 3.30 mm is a machine tap in HSSE cobalt grade, designed for producing metric ISO threads in blind holes and suited to general machining in unalloyed and low-alloy steels.

• HSSE cutting grade for higher wear resistance
• 6.3 mm (1/4") HexDrive shank for rapid changes
• Metric M4 thread with ISO2 (6H) tolerance
• Engineered for blind-hole threading, Form C/15° RSP

Faster tool changes that keep production moving

A short overall length and a 6.3 mm (1/4") HexDrive shank deliver rapid tool-change capability, reducing non-productive time on machining centres. The HexDrive format permits secure retention in collets and quick clamping in holders, which supports higher uptime and more consistent cycle times. For operations prioritising throughput, the combination of compact form and standard shank format simplifies integration into automated tool magazines while maintaining positional stability during tapping cycles.

Consistent thread quality in blind-hole applications

Designed to produce metric ISO threads with tolerance ISO2 (6H), the geometry ensures repeatable thread form even in blind-hole conditions. The Form C (15° RSP) specification and compliance with DIN 371 indicate a geometry tuned for chip control when threading into closed bottoms; this reduces the risk of chip packing and improves first-pass yield. The specified pitch 0.70 mm and thread details yield predictable assembly fit for M4 fastenings where accurate thread class is required.

Durability and material compatibility for everyday machining

The cutting material HSSE (high-speed steel with cobalt) provides improved wear resistance and hot-hardness compared with standard high-speed steels, supporting extended life when machining unalloyed and low-alloy steels up to 900 N/mm² tensile strength. This resilience translates into fewer tool changes and steadier surface finish, which benefits batch production and maintenance workshops that demand dependable tooling performance under varied operating conditions. The construction balances toughness and hardness to resist chipping while maintaining cutting-edge stability.

Practical specification summary for workshop planning

The tool’s compact overall length 63 mm and clear thread dimensions (M4 × 3.30 mm, pitch 0.70 mm) make it straightforward to specify in process sheets and tool lists. Compatibility with standard ISO thread profiles and the DIN 371 norm simplifies procurement and quality documentation. The combination of standardised shank, recognised tolerances and robust cutting alloy supports predictable lifetime and inventory consolidation across similar tapping tasks.
