Machine tap DIN 374B Universal MF12×1 mm HSS‑Co vapourised (6H) — TECWERK

The Machine tap DIN 374B Universal MF12×1 mm HSS‑Co vapourised (6H) is a straight‑flute machine tap designed for producing precise metric fine internal threads in a wide range of engineering materials.

• HSS‑Co for increased wear resistance
• Straight flutes with back‑tapered flanks
• Vapourised coating for extended tool life
• ISO fine thread MF12×1 mm, tolerance 6H

Consistent fine‑thread accuracy for demanding assemblies

The tap is manufactured to DIN 374B with a metric fine thread (MF12×1 mm) and ISO2 tolerance (6H), ensuring repeatable thread quality where fit and sealing are critical. The use of HSS‑Co (cobalt high‑speed steel) raises hot‑hardness and wear resistance compared with conventional high‑speed grades, which keeps dimensional stability longer under production loads. Specified to DIN standards, the tool provides an objective basis for process planning and quality assurance in industrial environments.

Improved chip control and reduced rework on through holes

Equipped with straight flutes and back‑tapered flanks, the tool promotes predictable chip formation and safe evacuation in through‑hole operations. The integrated through‑hole chamfer (Schälanschnitt) shortens the lead‑in and reduces thread burrs, lowering the need for secondary finishing. These geometric features translate into shorter cycle times and fewer rejects, which is particularly relevant where production efficiency and assembly reliability are priorities.

Durable finish and easy identification for busy toolrooms

A vapourised coating with the characteristic green ring provides enhanced surface hardness and corrosion resistance without obscuring cutting edges, supporting longer life in mixed‑material machining. The shank Ø 9 mm enables secure clamping in standard holders and quick tool changes, helping workshop operatives maintain steady throughput. The universal form B designation makes the tap a versatile choice across maintenance, fabrication and production settings where a balanced combination of performance and economy is required.

Suitable applications and integration into supply chains

Designed for use with steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals, this tap fits repair shops, toolrooms and industrial production lines where metric fine threads are specified. Compliance with recognised standards simplifies procurement and inspection processes. As a reliable partner for precision tools, Metav Werkzeuge supports supply continuity and offers technical advice to align tool selection with machining parameters and materials.

FAQ

Is this tap suitable for stainless steel?
The TECWERK machine tap is specified for stainless steels and is manufactured in HSS‑Co to improve wear resistance during stainless steel threading.

What thread tolerance and standard does the tool achieve?
The tool produces a metric fine thread MF12×1 mm to DIN 13 with an ISO2 (6H) tolerance field for consistent assembly fits.

Does the tap have a coating and how is it identified?
Yes, the tap features a vapourised coating and is identified by a green ring to denote the surface finish.

Can the tap be used for blind holes?
The geometry includes a through‑hole chamfer optimised for through threads; blind‑hole applications require process adjustment and are not the primary intent of this chamfer design.

What shank size is required for clamping?
The tap has a shank diameter of 9 mm for secure mounting in compatible holders.
