4mm Drilling Slot Cutter HSS-Co8 TiCN Coated Short 2-Flute Right-Hand DIN 327D - TECWERK

Benefit from the combination of HSS‑Co8 substrate, TiCN wear protection and a short two‑flute design for precise, long‑lasting keyway milling; order the cutter directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK Keyway Cutter DIN 327 D Type N — 4 mm, HSS‑Co8, TiCN‑coated, 2‑flute (Weldon shank)

The TECWERK keyway cutter delivers short, centre‑cutting performance for tight, form‑accurate slots and keyways in steel and stainless applications.

• HSS‑Co8 substrate with TiCN coating
• DIN 327 D Type N, centre‑cutting design
• Short 2‑flute cutter for precise keyways
• Weldon shank, 6 mm diameter for secure clamping
• Very good suitability for steel and stainless

High precision through hardened substrate and coating

The HSS‑Co8 base material paired with a TiCN coating offers a measurable improvement in tool life and surface finish when machining narrow slots. Built to DIN 327 D and featuring a centre‑cutting geometry, this short version reduces the need for secondary finishing by producing accurate, repeatable grooves in one pass. The combination of substrate and coating lowers wear and friction, which translates into fewer tool changes and improved productivity on repetitive tasks.

Material range and application limits explained

Designed for components up to approximately 1000 N/mm², the cutter performs very well on steel, stainless steel and cast materials; non‑ferrous metals and special alloys are conditionally suitable depending on parameters. The specification emphasises practical workshop use: the tool is intended for form‑accurate keyways and tight fits, so its strength lies in repeatable accuracy rather than heavy stock removal. The TiCN layer supports high contact pressures and thermal loads, helping to maintain edge integrity in continuous production.

Practical design features for reliable operation

A 2‑flute configuration minimises chip clogging in narrow slots while the Weldon shank with a 6 mm diameter and drive flat ensures secure clamping in tool holders. With a cutting length of 2 mm and an effective length of 7 mm, the short geometry offers reduced overhang and improved rigidity, which cuts vibration and enhances dimensional stability. The tool’s right‑hand cutting and centre‑cutting capability mean controlled plunging and axial engagement when aligning keyways or machining blind slots.

Productivity gains and workshop integration

Choosing a tool with this specification reduces rework and increases first‑pass accuracy, which supports faster throughput in small to medium‑batch production. The compact design suits confined setups and jigged operations where access is limited and repeatability is essential. For machining strategy, pair the cutter with a rigid holder and stable feeds to exploit the HSS‑Co8 toughness and TiCN wear resistance; this approach prolongs life and secures consistent slot geometry across runs.

FAQ

What materials can this keyway cutter machine effectively?
The TECWERK keyway cutter is very well suited for steel, stainless steel and cast materials and is conditionally suitable for non‑ferrous metals and special alloys; it is designed for components up to roughly 1000 N/mm².

Is the cutter suitable for blind keyways or requires through‑holes?
Thanks to its centre‑cutting geometry, the tool can be used for limited plunge operations and is therefore appropriate for certain blind keyways, provided the cutting length of 2 mm meets the required slot depth.

Which shank type is used and how is it held?
This tool uses a Weldon shank with a 6 mm diameter and drive flat, ensuring secure clamping in standard Weldon holders for stable machining and minimal slippage.

How does the TiCN coating benefit workshop use?
The TiCN coating reduces friction and increases wear resistance on the cutting edges, which improves surface quality and extends tool life under continuous or repetitive operations.

What is the article number for ordering and reference?
The cutter is available under article number 2000866108NW and is marketed by TECWERK as a DIN 327 D Type N, 4 mm, short keyway cutter.
