TECWERK End mill D844 Type N, Ø3 mm, HSS‑Co8, TiCN, Weldon shank

The TECWERK End mill D844 Type N is a long, 4‑flute HSS‑Co cutter designed for axial entry and high‑precision milling of steels and cast materials.

• HSS‑Co8 construction for long life
• TiCN coating for enhanced wear resistance
• Weldon shank, Ø6 mm, secure tool holding
• DIN 844, 4‑flute, centre‑cut for axial entry

Reliable, high‑speed capable performance in steel and inox

The tool is manufactured from HSS‑Co8, which provides a favourable balance between toughness and red hardness for interrupted cuts and elevated cutting temperatures. With a nominal diameter of Ø3 mm and an effective cutting length of 12 mm, the cutter permits controlled chip evacuation and consistent surface quality when machining steels and stainless steels. The TiCN coating reduces adhesive wear and heat build-up, extending tool life where coated tools are recommended up to higher hardness ranges; this results in fewer tool changes and improved process stability for production batches.

Secure clamping and geometry optimised for axial entry

A Weldon shank with a 6 mm shank diameter gives positive clamping in standard holders and collet chucks, reducing the risk of slippage during plunge milling and maintaining concentricity over long runs. Conforming to DIN 844 and featuring 4 flutes with a centre‑cut geometry, the cutter is capable of direct axial plunging without pre‑drilling, which simplifies fixture setups and shortens cycle times. The right‑hand cut profile supports conventional milling directions and predictable chip flow, enhancing both repeatability and finish in components.

Coating, material suitability and workshop integration

The TiCN surface layer offers improved wear resistance and lower built‑up edge tendency compared with uncoated HSS, making the cutter particularly suitable for production tasks in mixed‑material workshops. According to the tool design, the cutter is very well suited for steel and INOX, conditionally suitable for non‑ferrous alloys and special alloys; these limitations should guide feed and speed settings. Integrate this end mill into a standard tooling table and pair it with recommended coolant practices for best results; Metav Werkzeuge can advise on machining parameters for specific materials and part geometries, ensuring efficient adaptation into existing processes.

FAQ

What materials is this end mill best suited for? The TECWERK End mill D844 Type N is very well suited for steel and INOX and conditionally suitable for non‑ferrous metals and special alloys, with the TiCN coating improving performance on harder workpieces.

Can the cutter be used for plunge milling without pre‑drilling? Yes, the centre‑cut geometry and 4‑flute design allow axial entry and plunge milling; the Weldon shank supports secure clamping during direct plunges.

Which holder type is recommended for this cutter? Use a secure collet or Weldon‑capable holder sized for the 6 mm shank to ensure rigidity and concentric clamping for repeatable results.

How does the TiCN coating affect cutting performance? The TiCN layer reduces adhesive wear and heat accumulation, extending tool life compared with uncoated HSS‑Co and improving surface finish in many steel applications.
