TECWERK slot milling cutter DIN 844 Type N Ø 11 mm — HSS‑Co8 with TiCN coating, Weldon shank, 3‑flute long

A TECWERK slot milling cutter DIN 844 Type N Ø 11 mm engineered for precision slotting and keyway milling in steel, stainless steel and cast iron applications.

• HSS‑Co8 high‑cobalt substrate for long life
• TiCN coating for increased wear resistance
• Weldon shank with secure clamping surface
• DIN 844 Type N, 3‑flute long design

Robust substrate and coating for longer production runs

The tool is made from HSS‑Co8, a high‑cobalt high‑speed steel that resists heat and abrasion better than standard HSS. Combined with a TiCN (titanium carbonitride) coating, the cutter tolerates higher cutting pressures and reduces flank wear, which translates into longer service intervals and fewer tool changes. As a DIN 844 Type N design with a 3‑flute long geometry and central cutting capability, the cutter enables controlled slotting and limited plunge cuts, supporting efficient workflow in busy workshops and small‑batch production. The result is consistent part quality with reduced machine downtime.

Secure clamping and precise handling for accurate grooves

The Weldon shank provides a machined clamping face that improves torque transmission and reduces slippage in the tool holder, ensuring a steady rotation under load. With a 12 mm shank diameter and a relief (free cutting length) of 10.5 mm, the tool offers good support in the collet while allowing the required cutting engagement. The long version of the cutter improves access to deeper slots without compromising runout, so the cutter maintains dimensional tolerances and surface finish even in repetitive operations. These mechanical features support predictable tool life and repeatable groove geometry.

Material suitability and application limits explained

This cutter is optimised for machining materials up to 800 N/mm² tensile strength with an uncoated tool and up to 1000 N/mm² when the TiCN coating is applied; here N/mm² denotes tensile strength in megapascals, a common measure of a workpiece’s resistance to deformation. The geometry and material pairing make the cutter very suitable for steel, stainless steel and cast iron, while non‑ferrous metals and certain special alloys are conditionally suitable depending on cutting parameters. For workshop engineers and production managers, the practical benefit is fewer tool variants to cover common slotting tasks, improved surface quality and predictable processing windows for routine and specialised components.

FAQ

What materials is this slot milling cutter best suited for?
The TECWERK slot milling cutter is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and some special alloys are conditionally suitable depending on cutting data.

Can the cutter perform plunge cuts?
Yes, the DIN 844 Type N geometry includes a central cutting design that allows limited plunge milling in addition to conventional slotting.

How does the TiCN coating affect tool performance?
The TiCN coating increases wear resistance and enables machining of higher tensile strength materials up to 1000 N/mm² when appropriately applied, extending tool life and improving surface finish.

What benefits does the Weldon shank provide in production use?
The Weldon shank gives a machined clamping face for secure torque transmission and reduced slippage, improving repeatability and reducing the risk of tool runout during continuous operation.

Is this cutter available in other nominal diameters and tolerances?
The cutter range follows DIN 844 nominal diameters and tolerances; the 11 mm variant is supplied with tolerance h10 as part of the nominal Ø series
