VÖLKEL machine thread tap bit HSSE M3 x 0.50 – 1/4" hex shank, Form C

VÖLKEL machine thread tap bit HSSE M3 x 0.50 is a machine tap bit for producing ISO metric M3 threads in blind holes, designed for use in unalloyed and low‑alloy steels and suited to general workshop and light industrial production.

• HSS‑Co cutting material
• 1/4" (6.3 mm) hex shank
• Form C / 15° RSP geometry
• For blind‑hole ISO metric M3 threads

Consistent ISO threads for reliable assembly

This tap bit creates M3 x 0.50 threads to ISO2 (6H) tolerance, ensuring reliable fit and repeatable assembly results. The geometry conforms to DIN 371 (WN) and the Form C / 15° RSP profile supports standard machine tapping routines, so the component tolerances remain predictable across batches. Clear specification of tolerance and standardised form reduces rework and simplifies inspection procedures, making it suitable for production and repair environments that require traceable, repeatable thread quality. The VÖLKEL designation indicates a tool engineered for metric internal threads in blind‑hole situations.

Durable cutting performance in common steels

Manufactured from HSSE (cobalt high‑speed steel), the bit combines toughness with thermal stability to withstand typical workshop loads. It is specified for use in easily machinable materials up to 900 N/mm², including unalloyed and low‑alloy steels, where resistance to heat and abrasion extends tool life. The cobalt alloy increases performance under higher temperatures compared with standard HSS, so the tap bit maintains cutting edge integrity for longer production runs. For blind holes, the flute and rake design aid chip control, helping to avoid clogging and ensuring consistent thread form during interrupted or deep tapping cycles.

Quick changes and improved workstation throughput

The 6.3 mm (1/4") hex shank provides fast, secure engagement with standard bit holders and quick‑change tool receptacles, reducing setup time at the machine or driver. A compact 56 mm overall length and standard hex interface make this bit convenient for handheld screwdrivers as well as automated feeders where a bit holder is used. Faster tool changes translate to reduced downtime between operations and more efficient workflow on repetitive tasks. The combination of standard interface and machine‑grade cutting material supports both occasional maintenance work and continuous small‑batch production.

Practical applications and handling recommendations

Intended for general use, the tap bit is appropriate for maintenance shops, toolrooms and light production cells that require metric internal threads in components made from common steels. For blind‑hole tapping, adequate chip evacuation and suitable lubricant are recommended to preserve thread quality and tool life. The tool is supplied as a single‑piece pack, which supports selective stocking and replacement strategies. When used within the specified material limits and with proper chip evacuation, the bit contributes to fewer rejects and a more reliable assembly process.
