Keyseat cutter DIN 327 Type N, Ø4 mm – HSS-Co8, TiCN, Weldon shank (TECWERK)

A Keyseat cutter DIN 327 Type N designed for precision slotting and keyway milling in steel, stainless steel and cast iron, suitable for face and peripheral operations

• HSS-Co8 body with TiCN coating
• Centre-cutting, three-flute design
• Weldon shank with 6 mm diameter

Precision slotting with extended tool life

The HSS-Co8 substrate combined with a TiCN coating provides an optimised balance between toughness and wear resistance, which translates into longer tool life and reliable dimensional stability. The three-flute geometry and centre-cutting capability allow controlled material entry when plunging, while the short design improves rigidity. This results in predictable cuts and fewer rejected parts in production environments where repeatability matters.

Material compatibility and application limits

Engineered for demanding workshops, the cutter is rated for machining materials with tensile strengths of up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when used with a coated variant, making it well suited to steel, stainless steel and cast iron. Non-ferrous metals and certain special alloys are conditionally suitable; adjustments to cutting data are recommended in such cases. These specifications help to select feeds and speeds that reduce tool wear while maintaining the required surface finish.

Secure clamping and operational benefits

The Weldon shank with a 6 mm diameter and drive flat ensures positive drive transmission and simple tool changes in collets or holders designed for Weldon tooling. The right-hand cutting direction and short configuration favour rigid setups and reduce chatter during peripheral milling. The centre-cutting feature permits plunge operations for keyway entry, while the compact form minimises overhang, improving cycle times and achieving consistent slot geometry.

Supply reliability and practical support

Supplied as a short, three-cutting-edge tool it is optimised for machining deeper keyways and for both face and peripheral milling. Sourcing through Metav ensures access to a broad inventory and the group’s quality filter in Emmerich, so procurement is straightforward for workshops and industrial users alike. Metav’s experience in precision tools supports informed selection of cutting data and compatible holders, which helps to reduce setup time and maintain production continuity.

FAQ

Is this cutter suitable for stainless steel? The Keyseat cutter DIN 327 Type N from TECWERK is rated as very good for stainless steel and is appropriate for slotting and peripheral milling in most stainless grades when cutting data is adjusted.

Can the tool perform plunge cuts for keyway entry? Yes, the three-flute, centre-cutting geometry permits plunge operations, making the tool suitable for creating keyway entries and deeper slots.

What clamping system is required for secure use? The cutter features a Weldon shank with a 6 mm diameter and drive flat; a Weldon-compatible tool holder or clamping system is required for positive drive and secure retention.

Which materials should be avoided or tested carefully? Non-ferrous metals and certain special alloys are conditionally suitable; testing and reduced cutting speeds are advised to determine optimal performance before full production runs with this cutter.
