Keyway cutter DIN 327 Type N D 8 mm – HSS‑Co8, TiCN (TECWERK)

Keyway cutter DIN 327 Type N D 8 mm – HSS‑Co8, TiCN (TECWERK) is a compact, short‑length slot cutter for machining keyways and performing face and peripheral milling in a wide range of steels and cast irons

• HSS‑Co8 for high wear resistance
• TiCN coating extends tool life
• Weldon shank for secure clamping
• Centre‑cutting for plunge capability

Precision and longevity for repetitive keyway operations

The cutter combines a cobalt high‑speed steel substrate (HSS‑Co8) with a TiCN surface layer, resulting in improved wear resistance and thermal stability compared with unalloyed HSS. The three‑flute geometry balances cutting forces and chip evacuation, producing consistent surface quality in keyway faces. Where higher contact stresses occur, the coated tool increases the allowable tensile strength of workpieces from around 800 N/mm² (uncoated) to 1000 N/mm² (coated), offering a clear productivity advantage in short‑run and medium‑batch production. The overall effect is reduced tool change frequency and more predictable cycle times.

Secure mounting and stable cutting for accurate keyways

A Weldon shank with a 10 mm diameter ensures reliable clamping in powered holders and collet systems, reducing slippage during plunge and peripheral passes. The tool’s centre‑cutting capability allows direct axial entry, simplifying operations where end engagement is required. The short design increases rigidity, lowering deflection when cutting deeper keyways and improving concentricity. Right‑hand cutting geometry and the defined relief length of 7.5 mm contribute to repeatable dimensional results, which supports efficient downstream assembly and fitment.

Broad material suitability with clear operating limits

This cutter is very well suited for general steel, stainless steel and cast iron applications, while non‑ferrous metals and certain special alloys are conditionally suitable with adjusted feeds and cutting parameters. The designation DIN 327 Type N indicates a tool optimised for keyways and similar slots; when paired with the TiCN coating, the tool also copes better with slightly tougher workpiece conditions. For users seeking a reliable single‑tool solution for mixed workshop tasks, the combination of substrate, coating and geometry offers a pragmatic compromise between versatility and endurance.

Practical handling, tool life and shopfloor integration

As a short slot cutter it is straightforward to integrate into standard milling setups and CNC tool libraries. Use of cutting fluid or appropriate cooling will help maintain the TiCN layer and avoid thermal softening in prolonged engagements. Regrinding and refurbishment depend on the specific wear pattern; coated tools may be resharpened by specialists, but tool life is maximised by following conservative feed recommendations for harder materials. For specific cutting data or matching holders, a brief consultation will align the tool to the machine capability and workpiece requirements.

FAQ

What materials is this cutter best suited for?
The TECWERK keyway cutter is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable depending on feed and coolant choices.

Can the tool perform plunge cuts into the workpiece?
Yes, the Type N cutter features a centre‑cutting geometry that permits axial entry and controlled plunge milling when used with appropriate machine rigidity.

What size holder is required for the shank?
The cutter has a 10 mm Weldon shank, so a matching collet or Weldon‑compatible holder with secure clamping is required; ensure the holder provides adequate torque transmission for keyway milling.

Does the TiCN coating affect maximum material strength limits?
The TiCN coating increases wear resistance and heat tolerance, enabling machining in materials up to about 1000 N/mm² when coated, versus approximately 800 N/mm² with an uncoated tool.

Can this cutter be used for both face and peripheral milling of keyways?
Yes, the geometry and flute configuration are suitable for both face milling and peripheral passes when cutters are selected for the required slot depth and machine capability.
