Machine Tap Bit Set DIN 371/376 Form RSP 15° HSS‑Co — VÖLKEL

The Machine Tap Bit Set DIN 371/376 is a seven-piece metric tap kit designed for efficient machine tapping of ductile and easily machinable materials in workshop and production environments.

• HSS‑Co taps for ductile materials up to 900 N/mm²
• 1/4" (6.3 mm) HexDrive shank for machine use
• Metric ISO threads M3–M12 included
• Supplied in a durable plastic cassette

Consistent machine-grade thread quality for reliable production

The set provides taps manufactured to DIN 371 (M3–M10) and DIN 376 (M12) standards, ensuring reproducible thread geometry when used in powered tapping holders. Thanks to the HSS‑Co material, the taps maintain cutting edge integrity under continuous operation and elevated temperatures typical for high‑speed machining. The specified Form RSP 15° supports predictable chip formation and stable cut progression, which reduces thread runout and contributes to consistent component fit across batches.

Optimised for common workshop materials and machine use

These taps are specified for unalloyed and low‑alloy steels and other easily machinable workpieces up to 900 N/mm², offering a balance between toughness and red hardness through the cobalt‑alloyed high‑speed steel. The HexDrive 6.3 mm (1/4") shank is suited to standard quick‑change bit holders and tapping adaptors, enabling efficient changeovers on vertical machining centres, radial drills or dedicated tapping heads. The combination of material choice and shank design minimises tool breakage risk during interrupted cuts and helps to preserve thread accuracy.

Compact kit layout that streamlines workshop organisation

Delivered as a 7‑piece set, the kit contains one tap each for M3, M4, M5, M6, M8, M10 (DIN 371) and M12 (DIN 376), arranged in a practical plastic cassette for protected storage and clear tool selection. This ready‑to‑use configuration reduces downtime caused by searching for individual taps and supports a tidy tool cabinet or service trolley. The compact presentation also simplifies inventory control and replenishment planning in small and medium workshops.

Practical benefits for process efficiency and tool handling

Using machine‑grade tap bits with a standardised HexDrive interface accelerates set‑up and decreases tool change times, improving throughput in repetitive tapping operations. The cobalt alloy base of the cutters provides improved wear resistance compared with plain HSS in demanding cycles, which can extend effective tool life and reduce the frequency of replacement. For operations requiring reliable metric ISO threads across typical workshop materials, this set delivers a pragmatic combination of durability, compatibility and space‑saving storage.

FAQ

What sizes are included in the set?
The set contains one tap each for M3, M4, M5, M6, M8, M10 (DIN 371) and M12 (DIN 376), supplied in a plastic cassette.

Is this set suitable for machine tapping on a CNC mill?
Yes. The HexDrive 6.3 mm (1/4") shank is compatible with standard quick‑change holders and tapping adaptors used on CNC mills and tapping heads.

Which materials can be tapped with these tools?
The taps are specified for easily machinable materials, notably unalloyed and low‑alloy steels, up to 900 N/mm², using the HSS‑Co design for improved wear resistance.

What does Form RSP 15° mean for chip control?
Form RSP 15° denotes the tap profile provided in this set; it is suitable for controlled chip formation during machine tapping on ductile materials.

How does the material HSS‑Co benefit workshop use?
The cobalt‑alloyed high‑speed steel offers greater heat and wear resistance than standard HSS, which helps to extend tool life under sustained machine operation.
