TECWERK Slot Milling Cutter Type N, 4 mm — HSS‑Co8, TiCN, Weldon shank

TECWERK Slot Milling Cutter Type N is a long, centre‑cutting slot mill designed for precision slotting and short plunging operations in medium‑strength materials

• HSS‑Co8 high‑performance substrate
• TiCN coating for improved wear resistance
• Centre‑cutting two‑flute long design
• Weldon shank, 6 mm with drive flat

Consistent performance through advanced substrate and coating

The HSS‑Co8 base alloy combined with a TiCN surface layer offers a balance of toughness and thermal resistance that extends service intervals in everyday production. The 4 mm cutting diameter and long design provide access to deeper features while maintaining rigidity for small‑part work. The two‑flute geometry reduces cutting forces and enables stable chip formation; together these characteristics translate directly into fewer tool changes and higher overall machine uptime, supporting efficient workflows in busy workshops.

Secure clamping and dependable plunge machining

A purpose‑built Weldon shank with 6 mm shank diameter and drive flat gives firm clamping in the holder, reducing slippage during interrupted cuts. The centre‑cutting tip allows controlled plunging where a direct entry is required, while the moderate effective length 21 mm and a short cutting length deliver stable torque transmission. The free grind 3.9 mm aids chip escape and prevents packing in narrow slots, so the tool performs predictably even in repetitive production runs.

Material range and practical shop‑floor applications

The tool is specified for machining up to approximately ~1000 N/mm², with suitability ratings showing steel, stainless steel, and cast iron as very well suited for this geometry and coating. Non‑ferrous metals and certain special alloys are conditionally suitable depending on machining parameters. This makes the cutter a flexible solution for maintenance, prototyping and light production tasks across engineering workshops, toolrooms and small batch manufacturing. For tailored recommendations on feeds and speeds for particular alloys, Metav’s specialists can provide guidance.

FAQ

What materials is this cutter best suited for?
The TECWERK slot milling cutter Type N (SKU 2000866154NW) is rated very good for steel, stainless steel and cast iron, with conditional suitability for non‑ferrous metals and special alloys.

Can the cutter be used for plunge cuts?
Yes, the centre‑cutting geometry permits short plunge operations and controlled entry when a direct axial approach is required.

What are the shank and clamping details?
The tool has a 6 mm cylindrical shank with a Weldon drive flat for secure clamping in compatible holders.

How does the TiCN coating benefit the tool?
The TiCN coating reduces friction and increases wear resistance, extending tool life and improving performance in abrasive or demanding cuts.

Is this cutter suitable for continuous production use?
With an HSS‑Co8 substrate, TiCN coating and a robust Weldon shank, the cutter is designed for reliable performance in repetitive workshop and light production environments.
