8mm Solid Carbide End Mill DIN 844 Type N 4-Flute Long Centre Cutting, HSS-Co8 - TECWERK

Combine robust HSS‑Co8 construction with centre‑cut geometry and a secure Weldon shank to achieve stable long‑reach milling in medium‑strength materials; order the cutter directly via Metav Werkzeuge or consult our application specialists for tailored advice.

TECWERK End Mill DIN 844 Type N — Ø8 mm, HSS‑Co8, 4‑flute, Weldon shank

A TECWERK End Mill DIN 844 Type N engineered for long‑reach milling and plunge operations in medium‑strength steels and cast iron, fitted with a cylindrical shank and drive flat for reliable clamping.

• HSS‑Co8 high‑cobalt construction
• DIN 844 Type N long 4‑flute design
• Centre‑cut for plunge and profile milling
• Cylindrical shank with Weldon drive flat

Efficient cutting performance for medium‑strength materials

The tool combines a high‑cobalt HSS‑Co8 substrate with the DIN 844 Type N geometry to deliver consistent cutting forces and extended redress intervals when machining steels and cast iron. With a nominal diameter of Ø8 mm and a 44 mm cutting length, the cutter provides a good balance between reach and rigidity, reducing deflection in long‑reach passes. This translates into predictable machining cycles and fewer tool changes for improved throughput and lower per‑part processing time.

Geometry that enables plunge cutting and improved surface quality

A 4‑flute configuration with centre‑cutting edges allows safe vertical entry and efficient profile work, while the flute geometry supports reliable chip evacuation in continuous cuts. The right‑hand cutting direction and the multi‑flute design help maintain a finer surface finish on typical workshop steels, so fewer finishing passes are required. For operations that demand tight tolerances, the combination of flute count and centre‑cut capability provides stability and reduced chatter.

Secure clamping and straightforward tool handling

The cylindrical shank with a Weldon drive flat ensures positive torque transfer and stable seating in standard holders, which reduces slippage during heavy cuts. The familiar shank style simplifies tool changes across existing toolholders, lowering setup time at the machine. As a result, workshop routines stay efficient and downtime for re‑clamping is minimised, supporting continuous production flow and repeatable results.

Typical applications and machining recommendations

Best results are obtained when the cutter is used on steel and cast iron, where it is rated as very well suited; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting parameters. The tool is intended for materials up to approximately 800 N/mm² with uncoated cutters and up to 1200 N/mm² when a suitable coating is applied. For prolonged tool life, use moderate axial depths of cut and ensure adequate chip evacuation; adapt speeds and feeds to the alloy and machine rigidity to balance productivity and tool life.

FAQ

Which materials is this cutter best suited for?
The TECWERK End Mill DIN 844 Type N (SKU 2000866378NW) is very well suited for steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting conditions.

Can the cutter be used for plunge milling?
Yes, the centre‑cutting geometry permits plunge and ramp entry, enabling safe vertical entry without pre‑drilling for many profiling operations.

What clamping system is recommended for stable performance?
A rigid holder that accommodates a cylindrical shank with Weldon drive flat is recommended to ensure secure torque transmission and minimise slippage.

Is the tool suitable for hardened materials?
The cutter is intended for low to medium‑strength materials; consult Metav Werkzeuge for alternatives if machining pre‑hardened steels above the indicated strength ranges.

Are there specific feed and speed tips for longer tool life?
Use conservative axial depths of cut, ensure effective chip evacuation, and adjust cutting speeds to material and machine rigidity to balance productivity and tool life.
