TECWERK Slot Milling Cutter DIN 6527K Type N, 20 mm, Solid Carbide, TiAlN

An industrial slot milling cutter designed for vibration‑reduced roughing and finishing across steels, castings, stainless alloys and non‑ferrous materials

• Solid carbide (VHM) for high stiffness
• TiAlN coating for increased heat resistance
• Two‑flute design with centre cut
• Universally suitable for steel and NE‑metals

Precision and consistent performance for mixed materials

The TECWERK Slot Milling Cutter DIN 6527K Type N delivers repeatable results where a balance of rigidity and cutting efficiency is required. The tool’s VHM (solid carbide, fine‑grain) core provides high torsional stability, reducing deflection during heavy engagement, while the two‑flute layout maintains a favourable chip space for intermittent cuts. This combination results in consistent slot geometry and surface quality during both roughing and finishing, making the cutter suitable for batch production as well as individual component work. The integrated centre cut allows limited plunging operations, increasing process flexibility on machines with simple toolpaths.

Durable coating and carbide structure for extended tool life

A TiAlN coating forms a robust barrier against thermal loading and adhesive wear, extending life in elevated temperatures typical of steel machining. The fine‑grain solid carbide substrate supports a stable cutting edge and is particularly effective when interrupted cuts or abrasive inclusions are present. Together these characteristics reduce the frequency of tool changes and support longer cycle times between interventions. For operations where tool longevity improves uptime and lowers handling costs, the coated carbide design offers a reliable, low‑maintenance option.

Geometry engineered to reduce chatter and improve chip control

The cutter’s 45° protective chamfer and dynamically pitched flutes promote smooth entry and exit, reducing impact forces on the workpiece and minimising vibration. The dynamic helix assists with chip evacuation and helps prevent re‑cutting of swarf, which preserves edge integrity and improves surface finish. A modest protective chamfer (0.3 mm) protects the cutting edges during intermittent engagement, while the tool’s short form factor prioritises rigidity. These geometric choices yield clearer chip flow and reduced machine noise, which is particularly advantageous when machining thin‑walled components or interrupted surfaces.

Machine interface and handling benefits for workshop integration

Shank compatibility is designed to industrial standards: 20 mm shank diameter with h6 tolerance and a cylindrical shank manufactured to DIN 6535 HB for secure clamping and concentricity. The tool features a defined free clearance of 19.5 mm, allowing the cutter to reach constrained slots while maintaining neck clearance to avoid collisions. Right‑hand cutting direction and the short version make the tool well suited to horizontal and vertical machining centres as well as compact milling heads. Material suitability extends across steel, cast iron, grey cast iron, tempered castings, Cr‑Ni steels, non‑ferrous metals, aluminium with silicon content, special alloys and abrasive materials, providing a universal option for mixed‑material workshops.

FAQ

What materials can this slot milling cutter machine effectively? The TECWERK slot milling cutter is suitable for steel, stainless steel (INOX), cast iron, non‑ferrous metals, aluminium with silicon content and special alloys, as stated in the tool specification.

Is the tool suitable for both roughing and finishing operations? Yes. The combination of VHM substrate and TiAlN coating, together with the two‑flute geometry, enables both roughing and finishing with reduced vibration and improved surface quality.

Does the cutter allow plunging or only radial slotting? The tool features a centre cut, which permits limited plunging operations, extending its application range beyond pure radial slotting.

What shank standards and tolerances apply to this cutter? The cutter has a 20 mm shank manufactured to DIN 6535 HB with h6 tolerance for secure clamping and concentric running.

How does the TiAlN coating benefit machining performance? The TiAlN coating provides thermal and adhesive wear resistance, improving edge life in elevated temperatures and reducing the rate of wear during prolonged cuts.
