TECWERK Machine Tap DIN 371C M3×0.5 mm HSS‑Co, nitrided & vapourised

A TECWERK Machine Tap DIN 371C M3×0.5 mm designed for accurate production of ISO metric blind threads in high-strength and corrosion‑resistant steels

• HSS‑Co alloy for high-temperature strength
• Nitrided and vapourised surface treatment
• DIN 371C form C for ISO metric threads
• Ground flanks and 40° right‑hand helix

Consistent ISO threads for demanding materials

The tap follows DIN 371C and produces M3×0.5 mm ISO metric threads to ISO2 (6H) tolerance, ensuring a precise fit for assemblies requiring tight clearances. Manufactured in HSS‑Co, the tool resists deformation at elevated temperatures and maintains cutting geometry under load. Compliance with recognised thread standards reduces inspection time and simplifies component interchangeability, which benefits production planning and quality assurance.

Surface treatment that extends service life

The combination of nitrided and vapourised surface treatment increases surface hardness and wear resistance, resulting in longer tool life during serial production. The treated flute surfaces improve chip flow and reduce adhesion on sticky alloys, while the ground flanks help to form clean thread flanks and lower the risk of burr formation. These characteristics translate into fewer tool changes and reduced rework rates for thread machining processes.

Geometry optimised for blind holes and tough steels

With a 40° right‑hand helix and a geometry tailored for blind holes, the tap evacuates chips reliably from short axial depths and minimises the chance of chip packing. The tool is specified for machining stainless, acid‑ and heat‑resistant steels with tensile strengths above 850 N/mm², offering a robust solution where conventional taps would wear prematurely. The geometry choices combine to produce repeatable, high‑quality threads even in challenging workpiece materials.

Integration in machine workflows and handling

The tool features a shank Ø 3.5 mm, suitable for standard machine tap holders and collet chucks used in production lines. This compact shank supports stable clamping and concentricity, contributing to accurate thread form and reduced runout. Specified as a machine tap for industrial tapping operations, it is suited to automated or semi‑automated workflows where throughput and reproducibility are priorities. Metav’s distribution ensures access to spare items and consistent stock levels for uninterrupted production.

FAQ

What thread standard does this tap comply with?
The tap produces ISO metric threads to DIN 371C specifications with an ISO2 (6H) tolerance for precise fits.

Is the tap suitable for blind holes in stainless steel?
Yes, the TECWERK Machine Tap DIN 371C M3×0.5 mm is specifically designed for blind holes and for machining stainless and heat‑resistant steels with tensile strengths above 850 N/mm².

What material is the tap made from and how does that help?
The tool is made from HSS‑Co (cobalt high‑speed steel), which retains cutting performance at higher temperatures and extends tool life under heavy machining loads.

How does the surface treatment affect performance?
The nitrided and vapourised finish improves wear resistance and reduces adhesion of chips, which helps to maintain cutting geometry and reduces the frequency of tool changes.

What clamping or holder sizes suit this tap?
The tap has a shank Ø 3.5 mm, making it compatible with standard machine tap holders and collet systems commonly found on production equipment.
