VÖLKEL M12 HSSE machine tap bit — 1/4" hex shank, metric ISO thread, Form B

VÖLKEL M12 HSSE machine tap bit designed for efficient production of metric ISO threads in unalloyed and low-alloy steels, optimised for machine holders with a 6.3 mm (1/4") hex shank

• HSSE (HSS with cobalt) for higher wear resistance
• Metric ISO thread, tolerance ISO2 (6H)
• 6.3 mm (1/4") hex shank for machine holders
• Form B, DIN 376 standard, length 110 mm

Precision threads with industrial repeatability

The supplied machine tap bit is engineered to produce M12 metric ISO threads to ISO2 (6H) tolerance, ensuring consistent fit and interchangeability across mating components. Made from HSSE (high-speed steel with cobalt), the tool maintains cutting-edge hardness at elevated temperatures, which translates into prolonged tool life under continuous machine cycles. The Form B geometry and DIN 376 compliance simplify process planning: the standardised profile reduces variation between batches, enabling predictable assembly behaviour and fewer rejected parts.

Material capability and performance advantages

The tap bit is specified for general use in readily machinable materials up to 900 N/mm², including unalloyed and low-alloy steels. The HSSE substrate offers improved red hardness and resistance to abrasive wear compared with conventional HSS, which benefits high-throughput environments and light interrupted cuts. The included chamfer for through threads (Schälanschnitt) improves chip evacuation in through-hole tapping, lowering the risk of chip jams and reducing cycle interruptions—an efficiency gain that impacts overall productivity.

Simple machine integration and secure clamping

A 6.3 mm (1/4") hex shank allows direct insertion into common machine tool holders and quick-change adapters, eliminating time-consuming re-clamping while enhancing torsional stability during tapping. At a length of 110 mm, the tool balances reach and rigidity for typical bench and production centre setups. Compatibility with standard holders reduces fixture costs and supports rapid changeovers, which is particularly useful in mixed-production facilities where minimising downtime is crucial.

Practical guidance for application and process reliability

Form B execution and the tool’s geometry are optimised for through-thread operations; when pairing this tap bit with appropriate lubricants and correct spindle speeds, chip control improves markedly. For tapered or blind-thread operations, adjustments to cycle parameters and coolant strategy are recommended. Metav's technical literature gives process windows for spindle speed and feed adapted to HSSE taps in steels up to 900 N/mm², and Metav's technical team can advise on optimised parameters for specific setups.

FAQ

What materials is this tap bit suitable for?
The VÖLKEL M12 HSSE machine tap bit is intended for unalloyed and low-alloy steels and comparable materials up to 900 N/mm², providing reliable performance in commonly machined steels.

Which shank type does the tool use and why is that important?
The tap bit features a 6.3 mm (1/4") hex shank, allowing secure clamping in common machine holders and quick-change adapters for improved torsional stability and faster changeovers.

What does ISO2 (6H) tolerance mean for assembly?
ISO2 (6H) indicates a standard tolerance class for internal threads; using the VÖLKEL M12 HSSE tap bit achieves predictable thread fit and interchangeability with ISO-compliant mating parts.

Is the tool suitable for blind-hole tapping?
The geometry and chamfer are optimised for through-thread tapping; for blind-hole applications, process parameters and coolant strategy should be adapted—Metav's technical team can advise on suitable adjustments.

What standard does the tap conform to and why is this relevant?
The tool conforms to DIN 376 (WN), Form B, ensuring standardised geometry and processability, which supports consistent production quality and simplifies quality control.
