Take advantage of a short, robust keyseat cutter that combines HSS‑Co8 base material and a TiCN surface for improved wear resistance and reliable slot accuracy; order directly through Metav Werkzeuge or consult Metav for exact application advice.

Keyseat cutter DIN 327 Type N – 4 mm, HSS‑Co8 with TiCN, Weldon shank (short) — TECWERK

The Keyseat cutter DIN 327 Type N is a short, three‑flute cutter designed for milling deep keyways and slots in steels, stainless steel and cast components, with a Weldon shank for secure clamping.

• HSS‑Co8 construction for high wear resistance
• TiCN coating for extended tool life
• Weldon shank with 6 mm diameter
• Three flutes for smooth slot milling

Reliable performance for precision keyway milling

Built to the DIN 327 specification and manufactured in a compact short design, this keyseat cutter offers consistent results when machining tight keyways. The 4 mm cutter diameter combined with a cutting length 3 mm and effective length 7 mm delivers controlled chip formation and reduced vibration during both peripheral and face milling. The three‑flute geometry improves material evacuation and surface finish, which contributes to shorter rework cycles and higher process efficiency.

Clear guidance on material suitability and cutting limits

Application data shows excellent compatibility with steel and stainless steel and very good results on cast iron; non‑ferrous metals and special alloys are conditionally suitable. With an uncoated tool the cutter is suitable for materials up to around 800 N/mm² tensile strength and, when used with its TiCN coating, up to approximately 1000 N/mm². These figures support a rational selection of the tool for medium‑duty industrial production where predictable tool life and process stability are required.

Secure clamping and practical handling for workshop use

The Weldon shank and 6 mm shaft diameter ensure positive drive engagement and quick changes in standard Weldon holders or shrink fits. The centre cutting design enables limited plunge operations and accurate entry, while the short overall length (51 mm) minimises overhang for stiffer setups and better positional accuracy in deep groove milling. The right‑hand cutting orientation is optimised for conventional slot routing in common milling arrangements.

Coating and alloying for longer runtimes under load

The combination of HSS‑Co8 substrate and TiCN coating balances substrate toughness with surface hardness and lubricity. The cobalt‑enriched steel resists thermal softening during interrupted cuts and heavy engagement, while the TiCN layer reduces abrasion and offers an edge on machining tougher sections. For workshops seeking fewer tool changes and consistent cycle times, a coated short keyseat cutter is a practical, cost‑effective choice.

Application scenarios and workshop advantages

This short, three‑flute cutter is designed for producing pass‑keyways and deep slots on shafts and hubs, suitable for face and peripheral milling operations. Its compact geometry favours setups where tool stiffness and precise slot geometry are priorities. As part of Metav’s portfolio, the cutter benefits from a quality filter at the Emmerich location, providing reliable supply and professional advice for selection and handling.

FAQ

Which materials is this cutter best suited for?
The keyseat cutter (TECWERK, SKU 2000866202NW) is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable according to the application.

Can the cutter handle higher tensile strength materials?
The tool in its coated form can be used for materials up to approximately 1000 N/mm² tensile strength; uncoated use is recommended up to around 800 N/mm².

What shank and clamping system are required?
The cutter features a Weldon shank with a 6 mm diameter and is intended for Weldon holders or compatible clamping systems.

Is the cutter capable of plunging or only peripheral milling?
Thanks to its centre cutting geometry and three‑flute design, the cutter supports face (plunge) and peripheral milling for keyways and slots.

What advantages does the TiCN coating bring?
The TiCN coating extends tool life by improving surface hardness and reducing abrasion; combined with the HSS‑Co8 substrate it enhances performance on tougher sections.
