M3x0.5mm Machine Tap DIN 371B HSS-Co TiN Coated ISO2 6H Straight Flute - TECWERK

Take advantage of the combination of high wear resistance, precise ISO2 (6H) tolerance and a TiN surface for extended tool life — ideal for reliable series production. Order the machine tap directly via Metav Werkzeuge or ask our consultants if needed.

Machine tap DIN 371B M3×0.5 HSS‑Co TiN 6H – TECWERK

The Machine tap DIN 371B M3×0.5 HSS‑Co TiN 6H is a straight‑fluted metric tap for through‑threads, optimised for machining steels up to 1000 N/mm² in industrial and workshop applications

• HSS‑Co construction for high wear resistance
• TiN coating for longer tool life
• Straight flutes with ground flanks
• Tolerance ISO2 (6H) for metric threads

Reliable thread accuracy for repeatable assemblies

This tap follows DIN 371B and delivers the ISO2 (6H) tolerance required for consistent, interchangeable metric threads. The standardised profile ensures that threaded parts meet specification tolerances, reducing rework and scrap in series production. Precise geometry provides stable seating and predictable torque, which supports quality assurance processes and simplifies inspection routines.

High performance in demanding steels

Manufactured from HSS‑Co and finished with a TiN coating, the tool resists abrasive wear and retains cutting edge life when used on materials up to 1000 N/mm² tensile strength. The cobalt alloy increases red hardness for elevated cutting temperatures, while the TiN layer reduces friction and improves wear resistance — a combination that sustains productivity and lowers tool change frequency in medium‑duty production runs.

Design features that aid process reliability

The straight flutes and ground flanks promote reliable chip formation and evacuation in through‑hole applications, while the chamfer designed for through threads ensures quick engagement and consistent thread starts. The tap’s shank diameter of 3.5 mm provides secure gripping in collets or tap adapters, reducing the chance of slippage and improving concentricity on automatic tapping machines.

Practical application notes and workshop guidance

This metric machine tap is suited to automotive, mechanical and general engineering workshops for production and repair tasks requiring fine M3 threads. The tool is intended for use in machine tapping operations rather than hand tapping; appropriate coolant and correct spindle alignment will extend tool life and improve surface finish. For tailored recommendations on speeds, feeds and holder selection, Metav Werkzeuge can advise on the optimum process parameters for specific materials and setups.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap is designed for machining steels up to 1000 N/mm² tensile strength and is suitable for standard engineering steels in production environments.

Is this tap suitable for machine tapping or hand tapping?
The tool is intended for machine tapping operations; the straight flutes and shank diameter support collet mounting and automated processes for consistent results.

What does the TiN coating provide?
A TiN coating improves surface hardness and reduces friction, which extends the service life of the tap under elevated cutting temperatures and abrasive conditions.

How does the ISO2 (6H) tolerance affect fit?
ISO2 (6H) tolerance ensures a standardised thread fit for metric internal threads, delivering reliable assembly tolerances for mating fasteners and components.
