8mm Keyseat Cutter DIN 327 Type N HSS-Co8 Short 3-Flute Center Cut, 10mm Shank - TECWERK

The short, high-performance keyway cutter combines HSS‑Co8 material, a Weldon shank and centre‑cutting geometry to deliver precise deep keyways and reliable peripheral milling in steels and cast iron; order the TECWERK tool directly via Metav Werkzeuge or consult our technical advisers for specification matching.

TECWERK short keyway cutter — DIN 327 Type N, 8 mm, HSS‑Co8, 3‑flute

A short TECWERK keyway cutter (DIN 327 Type N, 8 mm) engineered for accurate slot and keyway milling, suitable for face and peripheral operations in workshop and light industrial environments.

• HSS‑Co8 for high wear resistance
• DIN 327 Type N geometry
• Three‑flute centre‑cut for plunge milling
• Weldon shank with drive flat

Precision and material advantages for demanding milling

The short slot cutter is manufactured from HSS‑Co8, a cobalt‑alloyed high‑speed steel that increases hot‑hardness and abrasion resistance compared with standard HSS. This composition makes the tool particularly suitable for machining steel and cast iron with consistent results. The DIN 327 Type N geometry optimises chip evacuation and tool stability, while the three‑flute layout balances cutting action and chip space — a design choice that supports accurate profile control and reduces chatter during both face and peripheral milling. The result is a measurable improvement in dimensional consistency when producing keyways.

Performance in typical applications and material limits

Designed as a centre‑cutting cutter with a Weldon shank, the tool enables plunge cuts as well as conventional slotting, making it suitable for producing deep keyways and pass‑key slots. The tool is specified for machining materials up to approximately 800 N/mm² with an uncoated blade and up to 1000 N/mm² when a suitable coating is applied, offering a clear reference for process planning. While the cutter performs very well in steel and cast iron, it is conditionally suitable for many non‑ferrous alloys and stainless steels; selection of cutting data and, where relevant, a coating will extend capability and tool life.

Handling, compatibility and machining setup

The short design, combined with a 10 mm shank and a 7.5 mm free cutting length, gives a compact tool that fits standard Weldon‑compatible toolholders and collet systems while reducing overhang for improved stiffness. The Weldon shank with drive flat secures the cutter against rotation under heavy intermittent loads. Right‑hand cutting direction and centre‑cutting capability support plunge entry and precise end‑face operations, so setup time is minimised and cycle reliability increases. For repeatable results, match spindle speed and feed to the indicated material strength and consider coolant or lubricant for stainless steels.

Durability, tool life and supply reliability

The combination of cobalt‑enriched steel and robust geometry provides a favourable balance between durability and cutting performance. Proper cutting parameters and the option of a coating for tougher materials allow process efficiency gains and reduced tool changes over production runs. Sourcing through an experienced supplier ensures consistent quality: Metav Werkzeuge acts as a quality filter for the European market, offering supply reliability and technical support that keeps workshop workflows running smoothly. This dependable supply chain reduces administrative overhead and secures continuity for maintenance and serial production.

FAQ

Is this cutter suitable for plunge cutting into a shaft?
The TECWERK short keyway cutter is centre‑cutting, so it supports plunge entries for slotting and keyway operations when set up with the correct feeds and speeds.

What shank size is required for tooling?
This item has a 10 mm shank and a Weldon drive flat, meaning it needs a compatible Weldon‑style holder or collet clamping system.

Can the cutter machine hardened steels?
The tool is specified for materials up to approximately 800 N/mm² uncoated and up to 1000 N/mm² with a coating; for steels above these limits, specialist tooling is recommended.

Is this cutter recommended for stainless steel?
Stainless steel (inox) is listed as conditionally suitable; careful selection of cutting data and consideration of a coating will improve results and tool life.

What operations is the cutter optimised for?
The cutter is optimised for producing deep keyways and performing both face and peripheral milling, offering good chip evacuation and stable cutting behaviour.
