Keyway cutter DIN 327 Type N, Ø 20 mm — short HSS‑Co8 TiCN, Weldon shank, 3‑flute by TECWERK

Keyway cutter DIN 327 Type N, Ø 20 mm is a short, centre‑cutting three‑flute cutter designed for milling deeper keyways and for both face and peripheral milling in workshop and industrial environments

• HSS‑Co8 high‑alloy tool steel core
• Durable TiCN coating for longer life
• Weldon shank with drive flat, Ø 20 mm
• Short three‑flute, centre‑cutting design

Consistent cutting performance with high‑alloy construction

The short, centre‑cutting design based on DIN 327 Type N provides reliable engagement when milling tight keyways. Built from HSS‑Co8, the tool offers a strong combination of toughness and red‑hardness for continuous use in production. The TiCN coating reduces abrasive wear and friction, translating into longer life and more consistent dimensional results — particularly beneficial where repeatability and runout control are critical for shaft and hub fits.

Secure clamping and rigid setup for precision results

A Weldon shank with drive flat and Ø 20 mm diameter gives positive drive and reduces slippage in heavy interrupted cuts. The short design improves rigidity, lowering chatter and improving surface finish during both face and peripheral milling. With a three‑flute geometry and centre‑cutting capability, the cutter permits plunge cuts and efficient chip formation, which helps maintain cycle times without sacrificing accuracy.

Clear material guidance and practical application limits

This cutter is engineered for keyway milling in a range of ferrous materials: steel, stainless steel, and cast iron are rated very good for machining with this tool. Non‑ferrous metals and special alloys are only conditionally suitable. The tool is intended for components with tensile strengths up to 800 N/mm² when used uncoated and up to 1000 N/mm² with coating assistance. Such specifications make the cutter suitable for maintenance, toolroom and small‑series production where controlled depth keyways and accurate fits are required.

FAQ

Which materials are best machined with this cutter?
The TECWERK keyway cutter DIN 327 Type N (SKU 2000866220NW) is very well suited to steel, stainless steel and cast iron; non‑ferrous metals and special alloys are only conditionally suitable.

Can the cutter perform plunge cuts or only peripheral milling?
Thanks to its centre‑cutting geometry and three‑flute layout, the cutter is capable of controlled plunge operations as well as face and peripheral milling for deeper keyways.

How is the tool clamped and secured in the holder?
The Weldon shank with drive flat and Ø 20 mm provides positive drive and secure clamping, reducing the risk of slippage during interrupted cuts.

What are the mechanical limits for workpiece strength?
The cutter is rated for workpiece tensile strengths up to 800 N/mm² with the uncoated tool and up to 1000 N/mm² when used with the TiCN coating for enhanced wear resistance.

Is this tool intended for large‑series production or workshop use?
The short, rigid design and high‑alloy construction make the cutter suitable for workshop, maintenance and small‑series production where precision keyways and reliable repeatability are required.
