TECWERK machine tap M3 x 0.5 mm (DIN 371B) – HSS‑Co PM, HARDLUBE, 2×D

The TECWERK machine tap M3 x 0.5 mm (DIN 371B) is a universal, machine‑grade metric tap designed for through‑thread production in steel, stainless steel, aluminium and copper alloys.

• HSS‑Co PM for extended tool life
• HARDLUBE coating reduces friction
• DIN 371 Form B, 2×D, straight flute
• Universal for steel, stainless and aluminium

Durable material for stable production cycles

Constructed from HSS‑Co PM (powder‑metallurgy cobalt high‑speed steel), this machine tap offers a balance of hardness and toughness that supports consistent performance under cyclic loads. The cobalt content raises hot‑hardness and wear resistance, which translates into longer tool life and fewer tool changes on the production line. This material choice is particularly beneficial where repeatability and reduced downtime are priorities, because it maintains cutting geometry over a greater number of cycles than standard high‑speed steels.

Geometry engineered for dependable thread quality

Built to DIN 371 in Form B with a metric ISO thread and tolerance 6HX, the tool delivers predictable thread fits for assembly and mechanical fastening. The tap's straight flutes and optimized edge rounding improve chip formation and evacuation in through holes, while the included chamfer (pecking/chamfer for through threads) eases engagement and reduces the risk of thread distortion. These geometric refinements minimise rework, ensuring components meet specification without repeated adjustments.

Versatile across common engineering materials

The tool is specified for universal use across steel, stainless steel, aluminium and copper alloys, as well as cast materials, making it suitable for mixed‑material production environments and repair workshops. The 2×D flute length provides adequate reach for standard through‑holes while retaining rigidity for accurate thread profile formation. With a shank Ø 3.5 mm and right‑hand cutting direction, it is ready for standard machine tapping spindles and holders found in many small to medium machining centres.

Coating and handling that improve process efficiency

The HARDLUBE surface treatment reduces friction at the cutting zone, supporting smoother chip flow and improved surface finish in the finished thread. Lower friction also lessens heat build‑up, which contributes to extended service life of the cutting edges. For best results in production, combine the coated tap with appropriate cutting fluid and stable clamping; the machine‑grade design allows for automated tapping cycles while preserving thread accuracy and repeatability.

FAQ

What materials can be processed with this machine tap?
The TECWERK machine tap M3 x 0.5 mm (DIN 371B) is specified for universal use, suitable for steel, stainless steel, aluminium and copper alloys as noted in the technical description.

How does the HARDLUBE coating help in production?
The HARDLUBE coating on the tap reduces friction at the cutting edge, which improves chip evacuation and surface finish while extending the life of the HSS‑Co PM cutting material in repetitive tapping cycles.

What does the 6HX tolerance mean for thread fit?
Tolerance 6HX indicates a standard metric tapping tolerance that ensures a controlled thread fit; the TECWERK DIN 371B tap produces threads that meet this common industrial specification for reliable assembly.

Is this tap suitable for machine tapping or hand use?
Designed as a machine tap in accordance with DIN 371, the tool is intended primarily for machine tapping operations; the shank Ø 3.5 mm and 2×D length suit standard machine holders and automated tapping cycles.

Why choose powder‑metallurgy HSS‑Co PM over conventional HSS?
Powder‑metallurgy HSS‑Co PM offers improved microstructure uniformity and higher wear resistance compared with conventional HSS, providing longer life and consistent cutting performance for the TECWERK tapping application.
