End mill DIN 844 Type N, Ø 8 mm – HSS‑Co8, Weldon shank (TECWERK)

The End mill DIN 844 Type N, Ø 8 mm is a short, 4‑flute centre‑cut cutter designed for precise milling of steel and cast iron in workshop and light industrial environments

• HSS‑Co8 high-cobalt high-speed steel
• DIN 844 Type N, 4 flutes, centre-cut
• Weldon cylindrical shank with drive flat
• Optimised for steel and cast iron machining

Robust cutting performance for demanding materials

Made from HSS‑Co8, this short 4‑flute cutter delivers a combination of toughness and wear resistance that suits demanding milling tasks. The high cobalt content increases red hardness and fracture resistance, making the tool appropriate for operations on components with higher mechanical loads. The specification allows machining of materials up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when a suitable coating is applied, which supports confidence in its use on medium‑strength alloys and hardened parts within those limits. The 4 flutes provide a balanced cutting edge geometry that promotes chip control and stable surface finish.

Short design for rigidity and precise machining

The compact length of this Type N cutter reduces overhang and improves bending stiffness, which in turn reduces vibration and improves dimensional accuracy in pockets and slots. Conforming to DIN 844 ensures repeatable geometry and compatibility with standard toolholders used in workshop milling. The centre‑cut geometry permits axial plunging where necessary, extending the range of operations beyond peripheral cuts while maintaining a predictable tool path. As a result, machines and fixtures operate more efficiently and yield parts with consistent tolerances.

Secure mounting and reliable torque transmission

The cylindrical shank with a Weldon drive flat offers a straightforward, secure clamping interface for Weldon‑style holders and similar chuck systems. This arrangement prevents slippage under higher torque loads and simplifies tool changes in busy production settings. The cutter is right‑hand cutting, matching standard spindle rotation and feed directions in most milling setups. Together these features reduce the risk of tool run‑out and contribute to safer, more reliable machining cycles.

Practical applications and workshop benefits

This cutter suits general workshop use, prototyping and small‑batch production where flexibility and robustness matter. It is very well suited to machining steel and cast iron, and is conditionally suitable for non‑ferrous metals and stainless steels depending on cutting parameters and tooling coatings. The short format shortens setup time and can reduce scrap by improving process stability. Combined with Metav’s approach to democratising precision—bringing high‑accuracy tools within reach of every workshop—this end mill supports a practical balance of performance and accessibility.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited to steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steels depending on cutting conditions.

Can this tool be used for plunge milling?
Yes, the centre‑cut geometry allows axial plunging; the cutter’s short design further supports stable plunge operations.

How is the tool clamped in the machine?
The cylindrical shank with a Weldon drive flat is intended for Weldon‑style holders and similar chucks to ensure secure clamping and torque transmission.

Does the tool specification indicate a maximum material hardness?
The tool is specified for machining up to 800 N/mm² uncoated and up to 1000 N/mm² when a suitable coating is applied.

Is the cutter suitable for high-speed machining?
The cutter’s HSS‑Co8 composition provides improved red hardness and wear resistance; suitability for high cutting speeds depends on machine capability and cutting parameters rather than the material alone.
