TECWERK machine tap DIN 371B M8×1.25 mm — HSS‑Co, ISO2 (6H)

The TECWERK machine tap M8×1.25 mm is a robust metric cutting tool designed for producing precise through threads in hard-to-machine steels and industrial components.

• HSS‑Co construction for high wear resistance
• Straight flutes with relieved flanks for clean chips
• Tolerance ISO2 (6H) for precise metric ISO threads
• Chamfer for through threads; shaft Ø 8 mm

Consistent industrial threads for production environments

The tap delivers reliable metric ISO threads in line with DIN 13 and DIN 371B, making it suitable for standardised assembly and interchangeable parts. The tolerance ISO2 (6H) ensures thread fit that matches industry expectations for clearance and engagement; this reduces the likelihood of rejects at assembly and supports repeatable production runs. For operations that require measurable, reproducible results, the defined tolerance class is a direct guarantee of dimensional accuracy.

Durability that eases maintenance intervals

Manufactured from HSS‑Co, the tool offers enhanced hot hardness and wear resistance compared with standard high‑speed steels, which translates into longer tool life when cutting tougher materials. The material selection is specifically intended for components exposed to heavy use; as a result, maintenance intervals are extended and replacement frequency is reduced. This material advantage supports predictable tool‑cost planning and helps to maintain production uptime.

Cutting geometry engineered for throughput and chip control

The straight flutes combined with relieved flanks provide a clean cutting action and effective chip evacuation when producing through threads. The design minimises torque peaks and reduces the risk of thread tearing in challenging alloys. The included chamfer for through threads shortens thread lead‑in, enabling faster engagement and smoother evacuation of chips through the workpiece—this improves cycle times for batch production and lowers the risk of tap breakage in continuous operations.

Clear application profile and simple workshop integration

This tap is specified for use on components including hard‑to‑machine steels with tensile strength above 1,000 N/mm² and is supplied with a shaft Ø 8 mm for secure clamping in standard toolholders and tapping machines. The combination of Form B, Type H geometry and the features listed supports straightforward integration into existing tooling sets and machine programmes. If compatibility questions arise, Metav provides product guidance and selection support to help match the tool to the machine and material at hand.

FAQ

What materials can this tap machine effectively cut?
The TECWERK machine tap is designed for hard‑to‑machine steels, including components with tensile strength above 1,000 N/mm²; it is manufactured in HSS‑Co to withstand these conditions.

Is the thread accuracy suitable for interchangeable parts?
Yes. The tool produces metric ISO threads to DIN 13 with tolerance ISO2 (6H), providing the repeatability expected for interchangeable mechanical assemblies.

Can the tap be used for blind holes as well as through holes?
The geometry is optimised for through threads thanks to the chamfer; for blind holes, application depends on machine setup and chip evacuation—review machining parameters before use.

What clamping size is required for this tap?
The tool features a shaft Ø 8 mm, compatible with standard holders and tap spindles that accept an 8 mm shank.

How does the straight‑flute design affect chip control?
Straight flutes with relieved flanks promote predictable chip formation and evacuation for through holes, reducing torque fluctuations and the risk of tap breakage.
