Machine tap DIN 371C M3×0.5, HSS‑Co, ISO2 (6H) — TECWERK

The Machine tap DIN 371C M3×0.5 is a universal machine tap designed for producing metric ISO blind threads in steel, stainless steel and non‑ferrous metals.

• HSS‑Co material for high wear resistance
• Universal Form C geometry for versatile use
• Vapourised coating with green identification ring
• Tolerance ISO2 (6H) for precise metric threads

Consistent, ISO‑class threads for critical assemblies

The tap is manufactured to DIN 371C and cuts M3×0.5 mm metric threads with ISO2 (6H) tolerance, delivering repeatable thread form suitable for parts where fit and function are essential. Compliance with DIN 13 standards ensures the thread profile meets established dimensional and tolerance expectations, which reduces the risk of assembly issues and subsequent rework. This precision contributes directly to process reliability and predictable component interchangeability in serial production.

Cutting geometry optimised for mixed materials and blind holes

Built from HSS‑Co and shaped to Form C, the tool combines wear resistance with a geometry that balances cutting stability and chip control. A 40° helix with right‑hand spiral and relieved flanks promotes controlled chip flow when machining into confined cavities, making the tap particularly effective for blind threads where evacuation is critical. The design suits machining of steel, stainless steel and non‑ferrous metals, offering universal performance across common workshop materials while maintaining tool life and surface finish quality.

Workshop efficiency through finish and handling details

The vapourised coating and green identification ring simplify tool handling and recognition at the machine. A clearly defined shank Ø 3.5 mm facilitates secure clamping and quick changeover in automatic or manual tapping heads. The combination of coating, material selection and geometry reduces downtime for tap changes and supports a predictable maintenance interval, so tapping operations remain efficient and the production flow steady.

FAQ

Is this tap suitable for blind‑hole threading in steel? Yes. The Machine tap DIN 371C M3×0.5 from TECWERK is specified for blind threads and is suitable for steel machining thanks to its HSS‑Co construction and chip‑managing geometry.

What does the ISO2 (6H) tolerance mean for assembly? ISO2 (6H) indicates a tighter internal thread tolerance class; the TECWERK tap produces threads within this ISO2 (6H) field, which supports consistent fits and reliable assemblies in serial production.

Can the tap be used for stainless steel and non‑ferrous metals? Yes. The tool’s Form C geometry and HSS‑Co material permit use across stainless steel and non‑ferrous metals, providing versatile performance for mixed‑material workshops.

How is the tool identified at the machine? The vapourised finish with a green ring provides quick visual identification of the TECWERK tap and its coating type, aiding tool management and changeover efficiency.

What collet or holder fits the shank? The tap features a shank Ø 3.5 mm, which is compatible with holders and collets specified for that diameter; check machine clamping specifications to ensure secure mounting for tapping operations.
