Machine Tap DIN 371B Universal M3 x 0.5 HSS‑Co, vapourised — TECWERK machine tap for metric ISO threads

The Machine Tap DIN 371B Universal M3 x 0.5 HSS‑Co vapourised is a precision machine tap designed for producing metric ISO threads in demanding materials; suited to automated tapping stations and conventional machine tools.

• HSS‑Co for high temperature strength
• Straight flutes for reliable chip evacuation
• ISO2 (6H) tolerance for accurate threads
• Shearing cut for clean through holes

Consistent thread quality for reliable production

The tool delivers repeatable results through the combination of HSS‑Co material and Form B geometry, which together increase heat resistance and edge stability during high‑rpm operations. The ISO2 (6H) tolerance and compliance with DIN 13 sheet 1 ensure that the produced threads meet established dimensional standards, reducing rework and assembly issues. By specifying a tool with these characteristics, process planners achieve measurable improvements in first‑pass yield and thread interchangeability.

Broad material compatibility reduces tooling variants

Designed for use in steel, stainless steel, spheroidal cast iron and various non‑ferrous metals, this tap minimises the need for multiple specialised tools. The straight flutes support effective chip evacuation in through‑hole tapping, while the shearing cut produces cleaner thread flanks and reduces burr formation. These features help to shorten cycle times and ease downstream finishing, offering a tangible economic benefit in mixed‑material production environments.

Practical design features that aid workshop handling

Attention to detail such as flank relief ground on the cutting edges and a defined shank Ø 3.5 mm make the tap straightforward to clamp and align in machine tool holders. The vapourised coating and visible green ring marking provide quick identification on the tool trolley and extra surface protection against wear. For maintenance, the robust design supports repeated resharpening cycles where appropriate, extending the service life and lowering total tooling cost per thread.

Integration into production and operator safety

This universal machine tap is optimised for automated feeding and conventional tapping heads alike, with a geometry that balances cutting performance and tool life. The straight‑flute configuration assists controlled chip flow, decreasing the risk of tap breakage in unattended operations. When combined with appropriate tapping speeds and reliable lubrication, the result is a stable process that supports continuous shifts and reduces unscheduled downtime.

FAQ

What sizes and thread form does this tap produce?
The TECWERK machine tap produces an M3 x 0.5 metric ISO thread in accordance with DIN 13 sheet 1 and the ISO2 (6H) tolerance class.

Is the tool suitable for stainless steel?
Yes, the HSS‑Co material and the tap geometry make the tool suitable for stainless steel as well as carbon steels and selected non‑ferrous metals.

How does the shearing cut affect thread finish?
The shearing cut on this machine tap improves chip control and produces cleaner thread flanks for through holes, reducing the need for secondary finishing.

Can this tap be used in automated tapping machines?
The universal geometry and straight flutes are compatible with automated tapping heads and conventional machine tool setups when combined with correct feed and lubrication.

What indicates the coated version on the tool?
The vapourised coating is accompanied by a visible green ring marking, which aids quick identification in the tool inventory.
