Keyway cutter DIN 327 Type N, 10 mm — HSS‑Co8, Weldon, 3‑flute (short) — TECWERK

The Keyway cutter DIN 327 Type N, 10 mm is engineered for milling keyways and slots in workshop and production environments, optimised for face and peripheral milling in steel and cast iron.

• HSS‑Co8 high‑cobalt cutting steel
• Weldon cylindrical shank with driving flat
• DIN 327 Type N, 3‑flute short design
• Suitable for deeper keyways and peripheral milling

Consistent production through high‑alloy cutting material

The cutter is made from HSS‑Co8, a high‑speed steel alloy with 8% cobalt that increases red‑hardness and wear resistance compared with standard HSS. That material choice translates into longer tool life under elevated cutting temperatures and more consistent results in medium‑duty production. The combination of DIN 327 compliance and a robust alloy provides a predictable basis for repeatable machining cycles and reduced downtime for regrinding or tool changes.

Stable torque transmission and chip control for reliable cycles

A Weldon shank with driving flat and the 3‑flute geometry ensure secure clamping and good torque transmission in demanding operations. The short design reduces overhang and vibration, improving surface finish during both face and peripheral milling. The centre‑cutting configuration allows axial entry for plunge operations where required, while the flute geometry supports efficient chip evacuation, decreasing the risk of built‑up edge and maintaining cycle stability.

Clear workpiece suitability and performance limits

This tool is intended primarily for machining steel and cast iron, with very good suitability in these materials; non‑ferrous metals and stainless steels are conditionally suitable depending on the application. Performance guidance indicates effective use up to approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when a suitable coating is applied, offering a pragmatic expectation of behaviour across common workshop steels. Key specifications such as cutting length 3 mm and effective length 21 mm define the engagement envelope and support planning for deeper keyway operations.

Seamless integration into workshop standards and tooling systems

Compliance with DIN 327 simplifies tool selection and replacement across standardised setups, and the 10 mm shank diameter matches common collet and chuck interfaces. The tool’s geometry and material make it a practical option for production and repair workshops seeking to consolidate tooling without sacrificing capability. When paired with Metav’s supply and inventory approach, the cutter forms part of a reliable, centrally sourced toolkit that reduces procurement complexity.

FAQ

Which materials is this cutter best suited for?
The TECWERK Keyway cutter DIN 327 Type N (SKU 2000866186NW) is very well suited to steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data and workpiece condition.

Can the cutter perform plunge cuts or axial entries?
Yes, the centre‑cutting geometry allows axial engagement for plunge operations, making the cutter suitable for both face and peripheral milling of keyways.

Why is a Weldon shank used and what benefit does it bring?
The Weldon cylindrical shank with driving flat ensures secure clamping and reliable torque transfer in high‑load machining, reducing slippage and improving repeatability in production cycles.

Is the tool suitable for deeper keyways?
The tool is designed for milling keyways with increased depth in face and peripheral operations, supported by an effective length of 21 mm that provides the necessary reach within the short design.

Does the cutter require a coating for harder materials?
Uncoated use is suitable up to around 800 N/mm²; applying an appropriate coating typically extends the usable range to approximately 1000 N/mm², improving wear resistance under higher loads.
