Machine thread tap DIN 371B AL M5 x 0.8 mm HSS‑Co 6H — TECWERK

The Machine thread tap DIN 371B AL M5 x 0.8 mm HSS‑Co 6H is a precision tapping tool for producing ISO metric internal threads in through‑holes, optimised for long‑chip, soft materials and industrial machine use

• HSS‑Co high‑speed steel with cobalt
• DIN 371B, Form B, Type AL geometry
• Straight flutes with undercut flanks
• Special chamfer for through threads

Consistent, machine‑grade thread quality for production environments

The combination of HSS‑Co material and the DIN‑specified Form B / Type AL geometry provides a balance of wear resistance and toughness that benefits repetitive, machine‑driven tapping operations. The 6H tolerance class corresponds to a precise ISO2 fit, ensuring reliable assembly performance and interchangeability in series production. For workshop managers, this means fewer rejects and reduced rework times thanks to stable cutting behaviour and predictable dimensional results.

Optimised cutting geometry for long‑chip, soft materials

Designed with straight flutes and flanks that are undercut, the tool evacuates swarf effectively when cutting aluminium and other long‑chip materials. The through‑hole chamfer (Schälanschnitt) reduces thread entrance friction and avoids chip packing in blind starts, which translates to smoother cycle times and less spindle stress on machine tapping heads. This geometry is particularly advantageous where cycle reliability and surface finish matter.

Practical features that simplify tool handling and changeovers

A compact shank Ø 6 mm ensures compatibility with common tool holders and quick‑change adaptors used in many automatic tapping units. The metric M5 x 0.8 mm specification and compliance with DIN 13 sheet 1 make the tap straightforward to integrate into existing production plans and CAM setups. Clear, standardised dimensions reduce set‑up time and support consistent results across multiple machines and operators.

Maintenance and application guidance for durable use

To preserve cutting performance, maintain appropriate spindle speeds and cutting lubricants for aluminium and other soft alloys; the cobalt‑alloyed high‑speed steel benefits from moderate coolant application to clear chips and control heat. The tapping tool is intended for through‑hole threads in long‑chip materials; when used within these parameters, tool life and thread quality are maximised, reducing downtime and lowering total production costs.

FAQ

What materials is this tap best suited for?
The Machine thread tap DIN 371B AL M5 x 0.8 mm HSS‑Co 6H is optimised for long‑chip, soft materials such as aluminium and similar alloys, where straight flutes and the through‑hole chamfer improve chip evacuation.

Can the tap be used in automatic tapping machines?
Yes; the tool’s shank Ø 6 mm and DIN‑compliant geometry make it suitable for use in machine tapping units and automatic heads designed for ISO metric threads.

What does the tolerance class 6H mean for assembly?
A 6H tolerance provides a standardised internal thread fit according to ISO2, offering predictable mating with bolts and screws and ensuring interchangeability in series production.

Is specialised coolant required when tapping with this tool?
Moderate application of appropriate cutting fluid is recommended to assist chip removal and heat control; the cobalt‑alloyed high‑speed steel benefits from proper lubrication, especially in continuous production.

Does the tap include any special chamfer for thread starts?
Yes; the tool features a through‑hole chamfer designed to ease thread entry and reduce chip accumulation at the start of the hole.
