TECWERK end mill DIN 844 Typ N, 8 mm — HSS‑Co8 with TiCN, 4‑flute, Weldon shank

TECWERK end mill DIN 844 Typ N 8 mm is a short, centre‑cutting four‑flute tool designed for precise milling of steel, stainless steel and cast components in general machining

• HSS‑Co8 substrate with TiCN coating
• Four‑flute, centre‑cutting geometry
• Weldon shank with drive flat
• Very good for steel and stainless steel

Durable substrate and coating for longer tool life

The combination of a HSS‑Co8 substrate and a TiCN coating provides a balance of red hardness and surface hardness that reduces flank wear in demanding operations. With a 4‑flute layout and short profile, the cutter gives controlled chip formation and reliable surface finish when machining medium‑strength materials. The tool’s centre‑cutting capability permits axial plunging operations, making it suitable for slotting and short pocketing tasks where a compact tool is advantageous.

Geometry and clamping for stable, repeatable performance

A Weldon shank with a drive flat ensures secure clamping in chucks and holders, reducing the risk of slippage during interrupted cuts. The tool is built to DIN 844 standards and features a right‑hand cut that aligns with standard machine setups. The shank diameter of 10 mm and the short overall length contribute to low overhang, which in turn improves vibration resistance and repeatability of dimensions in serial production.

Optimised dimensions for precision milling in steel and stainless

With an external diameter of 8 mm, cutting length of 4 mm and an effective length of 25 mm, the cutter is tailored to short‑reach operations where accuracy matters. The short flute length and compact design reduce deflection and help maintain tight tolerances on slots and shoulders. For uncoated machining the tool handles materials up to approximately 800 N/mm²; when used with the TiCN coating the capability rises toward 1000 N/mm², expanding its applicability in tougher jobs.

Practical application guidance and material suitability

The tool is classified as very well suited for steel, stainless steel and cast materials, while non‑ferrous metals and special alloys are conditionally suitable depending on cutting parameters and coolant strategy. Its centre‑cutting four‑edge geometry supports both finishing and certain finishing‑oriented roughing passes, providing a good surface quality with fewer passes. For applications requiring longer engagement or heavy stock removal, consider tools with extended flute length or different substrate grades.

FAQ

What material is the cutter made from and why is that important?
The TECWERK end mill is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that improves red hardness and wear resistance compared with standard HSS, which makes the tool more reliable for higher‑temperature cuts.

Is the tool suitable for stainless steel?
Yes, the tool’s TiCN coating and HSS‑Co8 substrate provide very good performance when machining stainless steel, offering improved wear resistance and surface finish in many standard applications.

Can this cutter be used for plunge milling?
The cutter features centre‑cutting geometry, so axial plunging and entry into material are possible; the short design is optimised for short‑reach plunge and slotting operations.

What clamping system is required for secure use?
The tool has a Weldon shank with drive flat, which secures positive locking in chucks and Weldon holders to prevent rotation under load.

Which machining tasks suit this short, 8 mm cutter best?
The short 4‑flute geometry and compact overall length make the cutter ideal for precision slotting, shoulder milling and intermittent cuts in steel and cast components where low overhang and high rigidity are required.
