Machine thread tap DIN 374C MF 12 x 1.5 mm HSS‑Co 6H — TECWERK

A machine thread tap DIN 374C MF 12 x 1.5 mm HSS‑Co 6H designed for forming metric fine threads in blind holes across a range of steels and long‑chipping non‑ferrous metals.

• HSS‑Co for high cutting performance
• 40° right‑hand spiral for chip evacuation
• Relief‑ground flanks for precise thread form
• Suitable for blind holes, shank Ø 9 mm

Consistent performance for demanding machining

The TECWERK machine thread tap is manufactured from HSS‑Co, offering superior wear resistance compared with standard high‑speed steels; this translates into longer service intervals and stable thread geometry under repetitive production conditions. Conformance to DIN 374C and the metric ISO fine thread specification means predictable results in series manufacture. For materials up to approx. 1000 N/mm² tensile strength, the material selection and geometry combine to reduce the frequency of tool changes and limit scrap rates, supporting a more efficient production flow.

Clean threads and controlled chip evacuation

The 40° right‑hand spiral and relief‑ground flanks promote regular chip formation and removal, which is particularly beneficial when producing blind holes. The spiral geometry guides chips away from the cutting edges, reducing the risk of chip jamming and improving surface finish in the thread root. With a manufacturing tolerance of 6H, the tap provides reliable interchangeability and precise fitment of mating parts, lowering rework and inspection needs in assembly processes.

Machine compatibility and straightforward integration

With a shank Ø 9 mm, the tool integrates into common machine tap holders and collet systems used in automated tapping stations and machining centres. The Form C design indicates a machine tap optimised for driven tapping operations, allowing straightforward implementation into existing tool sets. The compact geometry for the 12 x 1.5 mm fine pitch maintains thread accuracy while fitting typical production workflows, supporting consistent cycle times and predictable tool life.

Production benefits and supply assurance

Selecting a quality machine tap with these properties delivers measurable operational advantages: reduced downtime through extended tool life, fewer rejects thanks to accurate thread form, and smoother process control with improved chip handling. Metav Werkzeuge acts as a quality filter for the European market and offers supply reliability from its Emmerich location, backed by broad product availability and long‑term customer trust, which supports uninterrupted production planning.

FAQ

Which materials can be machined with this tap?
The TECWERK machine thread tap is suitable for steels up to approx. 1000 N/mm², temperguss and long‑chipping non‑ferrous metals as stated in the technical description.

Is the tap suitable for blind hole threads?
Yes — the tool is specified for blind hole applications and features a 40° spiral and relieved flanks to aid chip control in such conditions.

What standard and tolerance does the tap conform to?
The tap complies with DIN 374C and produces a metric ISO fine thread per DIN 13 with 6H tolerance.

What is the shank diameter and how does that affect holder selection?
The shank diameter is 9 mm, which is intended for common machine tap holders and collet systems that accept a 9 mm shank.

How does the spiral geometry influence chip behaviour?
The 40° right‑hand spiral promotes controlled chip formation and evacuation, improving thread root quality and reducing the likelihood of chip clogging in blind holes.

What are the core materials and construction of the tap?
Construction is HSS‑Co, which provides improved wear resistance and heat tolerance compared with standard HSS, supporting longer tool life under demanding conditions.
