5mm Drill Keyway Cutter HSS-Co8 TiCN Coated 3-Flute Short 52mm OAL, DIN 327 - TECWERK

Take advantage of a robust combination of HSS‑Co8 substrate and TiCN coating for extended tool life, plus a compact short design that improves rigidity and reduces chatter when milling keyways; order the keyway cutter directly via Metav Werkzeuge or ask the consultants if needed.

TECWERK Keyway Cutter DIN 327 Type N — 5 mm, HSS‑Co8, TiCN coated

The TECWERK Keyway Cutter DIN 327 Type N is a short, three‑flute cutter designed for precision keyway and slot milling in steels and stainless steels, suitable for face and peripheral operations

*TiCN coating for longer tool life
*HSS‑Co8 substrate for high toughness
*Three‑flute geometry for controlled chip flow
*Weldon shank Ø6 mm for secure clamping

Precise keyway milling for predictable production results

The short DIN 327 Type N configuration with a 5 mm diameter and three cutting edges is optimised for stable machining of keyways and narrow slots. The combination of a short overall length (52 mm) and an effective length of 8 mm increases rigidity, which reduces deflection and improves dimensional repeatability when performing both face and peripheral milling. The three‑flute design supports steady material removal with reduced vibration, translating directly into more consistent part tolerances and fewer rejected components.

Material and coating engineered for extended tool life

Built from HSS‑Co8 (cobalt‑alloyed high‑speed steel), the cutter offers elevated red hardness and toughness compared with standard HSS, making it well suited to interrupted cuts common in keyway production. The TiCN (titanium carbonitride) coating provides enhanced wear resistance and a lower coefficient of friction, enabling coated tools to handle steels up to approximately 1000 N/mm² versus roughly 800 N/mm² for the uncoated variant. This technical pairing reduces flank wear and extends useful tool life, lowering replacement frequency and downtime in mixed‑material production environments.

Secure clamping and functional features for workshop reliability

A Weldon shank Ø6 mm with a drive flat ensures reliable torque transmission and simple, repeatable clamping in collets or set‑screw holders. The cutter’s centre‑cutting capability supports limited plunge operations for precise positioning within a keyseat, while the right‑hand cutting direction suits standard spindle rotation. These design elements combine to simplify setup and maintain process stability, particularly when machining steels, stainless steels and cast iron — materials for which the tool shows very good suitability.

Practical advantages for day‑to‑day machining

For production and maintenance shops seeking efficient slot and keyway solutions, the three‑flute geometry balances chip evacuation with cutting edge engagement to reduce built‑up edge and heat concentration. The short version is especially advantageous where access is restricted or where minimal overhang is required to preserve concentricity. Given its compliance with DIN 327 Type N, the cutter integrates easily into existing tooling families and fixtures, supporting rapid changeovers and predictable cycle times in both single‑piece flows and batch production.

FAQ

Is this cutter suitable for stainless steel applications?
The TECWERK keyway cutter with HSS‑Co8 substrate and TiCN coating is very well suited to stainless steel machining and offers improved wear resistance in such applications.

Can the cutter be used for plunge milling into a workpiece?
Yes, the centre‑cutting geometry permits limited plunge operations, which is useful for starting a keyseat or positioning before lateral cuts.

What clamp size is required for this cutter?
The tool features a Weldon shank with a 6 mm diameter and drive flat; holders or collets matching Ø6 mm with set‑screw or Weldon fixtures are recommended.

How does the TiCN coating affect performance?
TiCN increases surface hardness and reduces friction, extending tool life and allowing the coated cutter to machine steels up to about 1000 N/mm² compared with lower limits for uncoated tools.

Is this cutter compliant with an industrial standard for keyways?
The cutter conforms to DIN 327 Type N, making it suitable for standardised keyway dimensions and ensuring compatibility with established fixture and process setups.
