Keyway cutter DIN 327 Type N, 12 mm, HSS‑Co8 – TECWERK

The Keyway cutter DIN 327 Type N is a short, three‑flute, centre‑cutting tool with a 12 mm Weldon shank, designed for milling deep keyways and slotting in steel and cast iron.

• HSS‑Co8 for enhanced wear resistance
• Weldon shank for secure clamping
• Short three‑flute design for deep keyways

Reliable performance for demanding keyway work

The short, robust geometry provides consistent material removal when milling keyways and similar slots. Machined from HSS‑Co8, the cutter combines toughness with heat resistance, enabling steady performance under interrupted cuts. The DIN 327 Type N form and three‑flute layout reduce chatter and support stable cutting in both face and peripheral milling operations, which helps maintain repeatable tolerances and longer tool life.

Proven suitability across common engineering materials

Designed for components with low to medium tensile strengths, the cutter is rated for machining up to approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when a suitable coating is applied. The geometry is very well suited for steel and cast iron, conditionally suitable for non‑ferrous metals and stainless steels. The tool’s right‑hand cutting action and centre‑cutting capability simplify plunge starts and slot entry, reducing setup complexity in small‑batch and production environments.

Geometry and handling that support deeper keyways

The compact length and relief 11.5 mm ensure a controlled cutting engagement when producing deeper keyways. The short design and precise flute form allow effective chip evacuation and minimise the risk of edge build‑up during extended slot depths. With a 12 mm cylindrical shank featuring a drive flat for secure seating, the cutter provides reliable transmission of torque and repeatable concentricity for precision milling tasks.

Integration into workshop and production workflows

This cutter suits machine shops and industrial production where repeatable quality and tool reliability are priorities. The combination of Weldon shank clamping and a sturdy three‑cutting‑edge layout supports higher feed rates and stable performance in intermittent cuts. For process planning, select coated variants to extend tool life under higher tensile materials; the tool’s construction makes it straightforward to standardise in a fleet of inserts or solid end mills for consistent workshop results.

FAQ

What materials is this cutter best suited for?
The TECWERK keyway cutter (DIN 327 Type N, SKU 2000866188NW) is very well suited for steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steel depending on cutting data and coating.

Can the cutter be used for plunge cutting at slot starts?
Yes. The centre‑cutting version of this short three‑flute cutter permits plunge entry, making it suitable for accurate slot starts and through‑slot operations.

What shank size and clamping form does the tool require?
The tool has a 12 mm cylindrical shank with a Weldon drive flat for secure clamping in standard Weldon holders and collets.

Is a coated version recommended for harder materials?
For higher tensile strength materials, a coated variant is recommended; the TECWERK HSS‑Co8 geometry can then be used up to around 1000 N/mm² with an appropriate coating to extend tool life.

For which types of milling is this cutter intended?
The cutter is designed for deep keyway milling, including both face (end) and peripheral milling of keyways and similar internal slots.
