TECWERK Machine Tap DIN 371B M3 × 0.5 mm — HSS‑Co, Form B (AL)

The TECWERK machine tap M3 × 0.5 mm is a straight‑flute DIN 371B tapping tool designed for producing precise metric ISO threads in long‑chipping, soft materials

• Cobalt-alloy high-speed steel HSS‑Co
• Straight-flute Form B, type AL
• ISO metric M3 × 0.5, tolerance ISO2 (6H)
• Optimised for through threads in soft materials

Robust cutting performance for consistent threads

The combination of HSS‑Co (cobalt‑alloy high‑speed steel) and the straight‑flute Form B / type AL geometry delivers thermal stability and wear resistance that matter during continuous production. These material and design choices increase the tap’s resistance to softening at elevated temperatures, enabling stable cutting behaviour on long‑chipping workpieces. The relieved flanks and the tool’s adherence to DIN 371B ensure that each thread meets the dimensional requirements of DIN 13 part 1, so interchangeability and assembly tolerances are maintained in serial production.

Reduced chip problems and practical machining advantages

Equipped with a peel cut for through threads, the tapping tool evacuates chips more reliably than conventional profiles, which lowers the risk of chip jamming in blind or through holes in ductile, long‑chipping materials. The straight flute profile produces predictable chip formation and simpler chip control, which benefits both manual and machine tapping operations. For basic setup, the specified shank diameter of 3.5 mm fits common collets and holders; confirm holder compatibility and clamping length before use to ensure optimal runout and thread quality.

Compliance, tolerances and workshop benefits

The tool is produced to metric thread standards with ISO2 (6H) tolerance, offering a balance between fit precision and assembly ease in mechanical components. The flank relief grinding reduces friction on thread flanks and improves surface finish of the internal thread, which can decrease torque during assembly and extend component life. Supplied as a single unit, the tap’s clear specification and standard conformity simplify inventory management and reduce procurement complexity for workshops and maintenance teams seeking reliable, repeatable tapping results.

FAQ

What materials is this tap intended for?
The TECWERK machine tap M3 × 0.5 mm is optimised for long‑chipping, soft materials, where the straight‑flute geometry and peel cut improve chip evacuation and thread quality.

What does HSS‑Co mean and why is it used?
HSS‑Co denotes cobalt‑alloy high‑speed steel; the cobalt increases hot hardness and wear resistance, enhancing tool life and performance during continuous tapping.

Is the tap suitable for through threads?
Yes, the tool features a peel cut designed specifically for through threads, which helps prevent chip clogging and supports uninterrupted machining.

What thread tolerance does the tap produce?
Threads are produced to ISO2 (6H) tolerance in accordance with DIN 13 part 1, providing standardised internal thread accuracy for assembly compatibility.

Which holders accept the shank diameter?
The shank diameter is specified as 3.5 mm; use compatible collets or tapping holders that accommodate this dimension and ensure correct clamping for minimal runout.
