Slot milling cutter DIN 844 Type N Ø10 mm HSS‑Co8 TiCN, Weldon shank, 3‑flute, long — TECWERK

The slot milling cutter DIN 844 Type N is a long three‑flute, centre‑cut tool designed for precision slotting and keyway milling in steel, stainless steel and cast materials under industrial conditions

• HSS‑Co8 high‑cobalt high‑speed steel
• TiCN coating for extended tool life
• Weldon shank with drive flat
• Centre‑cut three‑flute design

Precision, material and coating for longer tool life

The long three‑flute design with centre‑cut capability makes this tool suitable for interrupted cuts and plunge operations while maintaining axial stability. Constructed from HSS‑Co8, the cutter balances toughness and hardness for demanding tasks; the TiCN coating reduces abrasive wear and heat adhesion, thereby extending service life and improving process reliability. The geometry supports clean chip formation, reducing rework and keeping cycle times predictable.

Secure clamping and vibration control for consistent results

A Weldon shank with drive flat enables secure clamp force transmission and repeatable concentricity in collets and chucks, which is essential when milling deep slots or long keyways. The Ø10 mm shank and the tool’s long form reduce the need for frequent reclamping in series operations, improving throughput. The free cutting relief (approx. 9.5 mm) and three‑edge cutting geometry contribute to controlled chip evacuation and lower radial cutting forces.

Machining capability and application limits explained

Rated for general machining of medium‑strength materials, the cutter handles up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when used with the TiCN finish. Suitability is highest for steel, stainless steel and cast materials; non‑ferrous metals and special alloys are conditionally machinable depending on process parameters. The tool’s right‑hand cutting and robust flute design help achieve consistent surface quality and accurate slot dimensions in serial production.

Integration into standard production environments

Compliant with DIN 844 Type N, the cutter is available in standard nominal diameters with defined tolerances, enabling exchangeability in tool lists and CAM setups. As part of an organised supply chain, Metav Werkzeuge supports deployment with a broad range of complementary tooling and accessories, backed by decades of distribution experience from Emmerich. The combination of standard conformity and reliable logistics reduces procurement complexity for workshops and small production units.

FAQ

Which materials are best suited to this slot milling cutter?
The slot milling cutter DIN 844 Type N is very well suited to steel, stainless steel and cast materials; non‑ferrous metals and special alloys are conditionally machinable depending on cutting data.

Can this cutter perform plunge milling or centre plunges?
Yes, the centre‑cut geometry permits plunge milling and axial engagement, making the tool suitable for slot starts and interrupted cuts.

What shank and clamping are required for secure use?
A collet or chuck capable of accommodating a 10 mm Weldon shank with drive flat is required to ensure secure clamping and concentricity for the long version of the cutter.

Does the TiCN coating improve performance significantly?
The TiCN coating increases wear resistance and heat performance, extending tool life and enabling machining up to 1000 N/mm² in coated condition, compared with 800 N/mm² uncoated.

Which standards and sizes apply to the cutter and what is the SKU?
The tool conforms to DIN 844 Type N and is offered in nominal diameters Ø 9, 11, 13 and 15 mm with specified tolerances; reference SKU 2000866254NW for ordering and specification.
