Keyway cutter DIN 327 Type N D.8 mm HSS‑Co8, Weldon shank, Z=3 (short) – TECWERK

A compact keyway cutter DIN 327 Type N designed for precise milling of deep keyways and slots in steel and cast iron with high rigidity and secure Weldon clamping.

• HSS‑Co8 for enhanced heat resistance
• Short design for compact machine setups
• Weldon shank Ø10 mm for secure clamping
• DIN 327 Type N, three flutes for keyways

Consistent keyways with robust carbide‑grade steel

This compact three‑flute cutter combines the HSS‑Co8 alloy with a short overall length to deliver reduced bending and improved concentricity when milling keyways. The cobalt‑enriched high‑speed steel increases hot‑hardness and wear resistance, which supports longer tool life under elevated cutting temperatures. Designed to the DIN 327 standard, the tool provides centre cutting capability for both peripheral and limited plunge operations, enabling accurate slot depth control and consistent fit for keyed shafts.

Secure clamping and reduced setup time

A Weldon shank Ø10 mm with a drive flat enhances torque transmission and minimises slippage in the toolholder, promoting repeatable positioning in production runs. The short geometry improves stiffness, reducing chatter in compact setups and allowing higher feed rates within the stated material limits. With an effective length of 17 mm and defined cutting length, the design shortens tool change cycles and simplifies fixture planning, contributing to measurable productivity gains on small to medium series.

Material suitability and application limits explained

The cutter is optimised for components with moderate to high strength: very good results on steel and cast iron, conditional use on non‑ferrous metals and stainless steel (inox). In uncoated form the tool is suitable for materials up to 800 N/mm²; with an appropriate coating, capability increases to about 1000 N/mm². The right‑hand cutting direction is standard for conventional milling machines and CNC centres, providing predictable chip flow and surface finish when paired with suitable feeds and speeds.

Practical operation and workshop integration

Its short version is particularly suitable for confined spindle clearances or when tight run‑out and high rigidity are required. The Z=3 flute geometry balances chip evacuation and cutting edge engagement for keyway profiles, while the Weldon shank facilitates quick clamping in compatible holders. For procurement and process planning, the cutter is supplied as single units, making it straightforward to trial in sample runs before wider adoption in series production. Metav’s role as a precision partner ensures reliable supply and technical background information from Emmerich, supporting integration into existing tooling systems.

FAQ

Which materials are best processed with this cutter?
The TECWERK keyway cutter is very well suited to steel and cast iron, with conditional performance on non‑ferrous metals and stainless steel according to the hardness and machining parameters.

Is the Weldon shank compatible with standard holders?
Yes, the Weldon shank Ø10 mm provides a secure drive in standard Weldon holders and collets designed for Weldon flats, improving clamping reliability for repetitive operations.

Can the cutter perform plunge cuts?
The centre‑cutting geometry allows limited plunge operations as well as peripheral milling, making it suitable for producing keyways with depth from both face and circumference.

What advantage does HSS‑Co8 offer over standard HSS?
The HSS‑Co8 composition contains cobalt to increase hot‑hardness and wear resistance, extending tool life at elevated cutting temperatures compared with conventional HSS grades.

What are the key dimensions to consider when integrating the tool?
Important values are the 8 mm cutting diameter, 61 mm overall length, 3 mm cutting length and 10 mm shank diameter; these define reach, rigidity and holder compatibility.
