Benefit from the combination of HSS‑Co8 heat resistance, a three‑flute geometry and a secure Weldon shank for stable, repeatable keyway milling; order the tool directly via Metav Werkzeuge or consult the advisers for specification and integration support.

Keyway cutter DIN 327 Type N, Ø 6 mm, HSS‑Co8 – TECWERK

A Keyway cutter DIN 327 Type N for precise milling of deep keyways and for face and peripheral milling in steel and cast iron applications

• HSS‑Co8 high‑cobalt grade
• DIN 327 Type N, three‑flute design
• Weldon shank with drive flat
• Suitable for steel and cast iron up to 800 N/mm²

Durable cutting performance for demanding production

The short, three‑flute geometry made from HSS‑Co8 (high‑speed steel with 8% cobalt) provides enhanced heat resistance and improved wear behaviour under heavy cutting. This composition prolongs cutter life when machining medium‑strength materials and reduces the risk of thermal softening during extended cycles. The centre‑cutting design enables limited plunge operations, while the right‑hand cutting direction supports standard spindle configurations. The result is a robust tool that sustains consistent cutting performance and reduces unexpected downtime.

Stable drive and precise keyway results

A Weldon shank with drive flat and a 6 mm shank diameter ensure secure clamping and low runout in standard tool holders. The short design provides higher rigidity close to the cutting edge, which translates into accurate keyway dimensions and cleaner surface finishes during both face and peripheral milling. The specified relief diameter of 5.5 mm helps to avoid unnecessary contact behind the cutting edge, reducing rubbing and heat build‑up. These features together deliver reproducible cuts and minimise rework in serial production.

Clear material suitability and application limits

This cutter is specified for machining workpieces with material strength up to approx. 800 N/mm² with the uncoated geometry; when used with an appropriate coating, applications can extend towards 1,000 N/mm². It is very well suited to steel and cast iron, while non‑ferrous metals and stainless steels are described as conditionally suitable — demanding adapted cutting parameters and potentially coated variants for optimal life. The primary application is the milling of keyways (passfedernuten) with larger depths, plus versatile use for both face and peripheral milling tasks.

Integration into workshop workflows and efficiency gains

The short keyway cutter’s compatibility with common toolholders and its Weldon drive reduce changeover time and simplify tool setup. The cutter’s geometry supports stable chip formation in medium‑strength materials, promoting higher feed rates and consistent cycle times. For procurement and maintenance planning, the compact design and reliable material combination lower the total cost of ownership by extending service intervals and reducing scrap. For technical clarifications or application advice, Metav’s specialists can provide guidance on cutting data and tool integration to align the tool with existing machining centres.

FAQ

What is the primary application of this cutter?
The TECWERK keyway cutter (DIN 327 Type N) is designed primarily for milling keyways with greater depth and for both face and peripheral milling in workshop and production environments.

Which materials are best machined with this cutter?
This short, HSS‑Co8 cutter is very well suited to steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable and may require adapted cutting data or a coated variant.

What shank diameter and clamping style does the tool use?
The cutter features a 6 mm cylindrical shank with a Weldon drive flat for secure clamping and low runout in standard holders.

Can the cutter perform plunge cuts?
The centre‑cutting geometry allows limited plunge operations, enabling controlled engagement when starting keyways or interrupted cuts.

How does the HSS‑Co8 material affect tool life?
The 8% cobalt alloy in HSS‑Co8 improves heat resistance and toughness compared with standard HSS, which helps maintain cutting edges under higher temperatures and extends service life in medium‑strength materials.
