20mm Drill Groove Cutter DIN 327D Type N HSS-Co8 TiCN Coating Weldon Short, 19mm Relief - TECWERK

Combining a HSS‑Co8 core with a TiCN coating and a secure Weldon shank delivers consistent keyway machining, precise fits and dependable tool life. Procure TECWERK keyway cutters through Metav Werkzeuge for reliable supply from Emmerich or consult our specialists for application advice.

TECWERK Keyway Cutter DIN 327 D Type N, Ø20 mm, HSS‑Co8 TiCN

The TECWERK keyway cutter DIN 327 D Type N Ø20 mm is a short, two‑flute, centre‑cutting slotting tool designed for accurate keyseats and narrow, form‑true grooves in metals of low to medium strength.

• HSS‑Co8 core with TiCN coating
• Two‑flute, centre‑cutting geometry
• Weldon shank with drive flat
• Very good for steel, INOX and cast iron

Accurate slotting for tight fits and keyseats

This short, two‑flute cutter is engineered for precision when machining narrow keyways and passfedernuten. The DIN 327 D Type N geometry ensures a consistent profile and repeatable dimensions, which reduces secondary finishing and fit adjustments. The centre‑cutting design permits controlled plunge starts for slotting operations while the two‑flute layout balances chip evacuation and cutting stability, delivering the dimensional control required for tight assemblies.

Durability and consistent cutting performance

The combination of HSS‑Co8 substrate and TiCN coating improves wear resistance and edge life under intermittent and continuous milling loads. TiCN lowers friction and helps maintain cutting edge integrity, which translates into longer intervals between tool changes and steadier surface quality. This robustness supports cost‑effective production runs where tool life and component finish are critical performance metrics.

Secure clamping and operational convenience

A Weldon shank with drive flat provides positive torque transmission and reliable clamping in standard toolholders, minimising slippage during axial and radial loads. With a shank Ø 20 mm, an overall length of 88 mm and an effective length of 36 mm, the tool fits typical holders while the 19 mm relief length supports close‑in machining without compromising rigidity. The short design reduces overhang and vibration, improving surface finish and dimensional stability in narrow slots.

Material suitability and recommended applications

Designed for machining materials up to approximately 1000 N/mm², the cutter is very well suited for steel, stainless steel (INOX) and cast iron, while non‑ferrous metals and high‑performance alloys are only conditionally suitable depending on cutting data and coolant strategy. Typical applications include precision keyways, deep keyseats where sided clearance is limited, and form‑true grooves for transmission components. The tool’s right‑hand cutting orientation and centre‑cutting capability make it appropriate for both conventional milling and plunge‑start operations where accurate slot placement matters.

FAQ

Can this cutter be used for plunge cutting into a pre‑drilled hole?
Yes. The TECWERK keyway cutter DIN 327 D Type N is centre‑cutting, which allows controlled plunge starts and direct slotting from a pilot hole when set up correctly.

Which toolholder is required for safe clamping?
Use a standard Weldon‑style holder compatible with a 20 mm shank and drive flat; the Weldon shank on the TECWERK tool secures torque transfer and reduces the risk of slippage.

Which materials are best machined with this cutter?
The cutter is specified for materials up to ≈1000 N/mm² and is very well suited to steel, stainless steel (INOX) and cast iron; non‑ferrous metals and special alloys are conditionally suitable depending on cutting parameters.

Is the short version suitable for deep keyways?
Yes. The short design improves rigidity and reduces vibration for deeper, narrow keyways, while the effective length of 36 mm supports extended engagement when required.

What advantage does the TiCN coating provide?
The TiCN coating on the HSS‑Co8 substrate reduces friction at the cutting edge, enhances wear resistance and contributes to more consistent surface finish and longer tool life for the TECWERK keyway cutter SKU 2000866126NW.
