4mm Slot Drill DIN 327D Type N HSS-Co8 TiCN Coated, Weldon Shank - TECWERK

Benefit from the combination of HSS‑Co8 construction and TiCN coating for extended tool life and consistent accuracy when milling deep, narrow keyways; order the cutter directly via Metav Werkzeuge or consult their specialists for application-specific advice.

Slot milling cutter DIN 327D Type N, 4 mm — HSS‑Co8, TiCN, Weldon shank (TECWERK)

A compact slot milling cutter DIN 327D Type N Ø4 mm designed for precise machining of narrow, form‑accurate keyways and deep slots in steel and stainless steel.

• HSS‑Co8 base material for heat resistance
• TiCN coating for longer tool life
• Weldon shank with drive flat
• Ideal for precision keyway and slot milling

Consistent precision for tight fits and deep keyways

The short, two‑flute, centre‑cut design delivers precision when machining narrow slots and deep keyways. A nominal cutting diameter of 4 mm combined with the 2‑flute geometry reduces chatter and produces clean wall finishes, which is essential for form‑accurate fits. For workshops requiring consistent tolerances, the tool’s compact configuration improves rigidity and repeatability, making it suitable for both repair work and small‑batch production where dimensional control matters.

Built to withstand demanding cuts and extended use

Made from HSS‑Co8, the tool resists thermal softening and maintains cutting edge integrity during heavy engagement. The TiCN surface layer lowers friction and increases abrasion resistance, extending tool life and reducing frequency of tool changes. These characteristics translate into fewer interruptions on the shop floor and improved machining throughput, particularly when working on components with material strength up to approximately 1000 N/mm².

Secure clamping and controlled cutting behaviour

The Weldon shank with a drive flat and a 6 mm shank diameter ensures positive drive and secure holding in standard milling holders or adaptors. The short overall length minimises overhang, increasing stiffness and enabling more controlled, repeatable cuts. Right‑hand cutting orientation and centre‑cut capability permit plunge and slot entry where required, simplifying set‑up and reducing the need for pre‑drilling in many applications.

Practical workshop applications and material suitability

This cutter excels when generating precision keyways, narrow spline slots and other form‑accurate internal profiles in steel, stainless steel and cast iron, where surface finish and dimensional fidelity are priorities. Non‑ferrous metals and special alloys can be machined conditionally, though performance depends on specific alloy composition and cutting parameters. For complex or unfamiliar materials, Metav’s technical advisors can recommend suitable feeds and speeds to maximise tool life and part quality.

FAQ

What materials is this slot cutter best suited for?
The TECWERK slot milling cutter is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable depending on the specific material.

Can the tool be used for plunge cutting?
Yes, the centre‑cut geometry allows plunge entry and slotting operations without prior drilling in many cases, supporting efficient keyway production.

What are the shank and cutter dimensions?
The cutter diameter is 4 mm and the shank diameter is 6 mm; it features a Weldon shank for secure clamping.

How does the TiCN coating improve performance?
The TiCN coating reduces friction and increases abrasion resistance, which helps to extend tool life and maintain consistent surface quality during extended runs.

Is this cutter suitable for deep, form‑accurate keyways?
Designed specifically for narrow, form‑accurate fits, the short two‑flute configuration provides the rigidity and finish quality required for deeper keyways.
