18mm Drilling Groove Cutter DIN 327 Type N HSS-Co8 TiCN 3-Flute Short Weldon 16mm Shank - TECWERK

Benefit from durable, high‑temperature performance and standardised geometry for consistent keyway milling; the short, centre‑cut design reduces setup time while the TiCN finish extends tool life. Order this cutter directly via Metav Werkzeuge or consult our specialists for compatibility advice.

Keyseat cutter DIN 327 Type N, Ø 18 mm, HSS‑Co8, TiCN — TECWERK

The Keyseat cutter DIN 327 Type N is a short, centre‑cut slot milling cutter designed for precision keyway and slot work in workshops and production environments

• DIN 327 Type N standardised cutter
• TiCN coating for improved wear resistance
• HSS‑Co8 construction for heat resistance
• Weldon shank Ø 16 mm for secure clamping

High performance and material suitability for demanding applications

The combination of HSS‑Co8 substrate and TiCN coating yields a tool that balances toughness and surface hardness. The cobalt‑alloyed high‑speed steel provides elevated red hardness and resistance to thermal softening, while the TiCN layer reduces friction and increases wear life; this translates into longer intervals between tool changes and more consistent component finish. The cutter is specified for machining materials up to ~800 N/mm² with uncoated geometry and up to ~1000 N/mm² when coated, making it particularly effective on steel, stainless steel and cast iron; non‑ferrous metals and special alloys are usable with appropriate parameter adjustments.

Design features that secure precision and handling

With a nominal Ø 18 mm cutting diameter and a shank Ø 16 mm, the tool features a Weldon shank with drive flat to ensure positive clamping in milling holders. The short design and centre cutting geometry allow both peripheral and limited plunge operations, while the 3 cutting edges deliver stable engagement and reduced vibration in keyway profiles. Important dimensions such as overall length 79 mm, effective length 29 mm, free cutting length 15 mm and cutting length 3 mm are engineered to fit compact set‑ups and to limit overhang, thereby improving rigidity and surface quality on the workpiece.

Practical advantages and application guidance for workshop use

As a right‑hand cutting tool with standardised DIN 327 Type N geometry, this cutter simplifies process planning for keyseat and deep slot milling operations. The centre‑cut capability reduces the need for pre‑drilled starter holes in many applications, shortening cycle times and lowering handling steps. In mixed production scenarios the robust HSS‑Co8 body tolerates occasional interruptions and higher thermal loads, while the TiCN coating helps prevent built‑up edge when machining stainless steel grades. Pairing the cutter with stable clamping and appropriate feeds ensures repeatable slot dimensions and minimal rework, supporting a smoother production flow across small shops and larger fabrication lines.

FAQ

Which materials is the cutter best suited for?
The keyseat cutter is optimised for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable depending on cutting parameters and coating.

Can the cutter be used for plunge cutting?
Yes, the centre‑cut geometry permits plunge operations within the limits of the short design and the specified cutting length.

What shank diameter and clamping are required?
The tool has a 16 mm Weldon shank and requires a holder that accepts a 16 mm shank with a drive flat for secure clamping.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and reduces friction, which improves wear resistance and allows machining up to ~1000 N/mm² under appropriate conditions.

Is the cutter compliant with industry standards?
The cutter is manufactured to DIN 327 Type N geometry, ensuring interchangeability and predictable keyway profiles in standardised applications.
