Slot milling cutter DIN 6527K Type N — Ø20 mm, solid carbide, TiAlN — TECWERK

The Slot milling cutter DIN 6527K Type N is a short, three‑flute solid carbide cutter with centre cut and cylindrical shank, engineered for vibration‑reduced slotting, plunging and finishing across a wide range of industrial materials

• Solid carbide fine-grain for extended tool life
• TiAlN coating for thermal and abrasive resistance
• Three‑flute centre‑cut for secure plunging
• Cylindrical shank to DIN 6535 HB for machine compatibility

Durable construction for high productivity

Constructed from solid carbide (VHM) with a fine‑grain microstructure and finished with a TiAlN coating, this short cutter delivers elevated resistance to heat and abrasive wear. The chosen substrate and coating combination reduce flank wear at higher cutting temperatures, which translates into longer intervals between regrinds and fewer tool changes. The short design offers greater rigidity at the cutting edge, giving consistent chip formation during both roughing and finishing cycles and supporting stable tool life in shopfloor conditions.

Controlled cutting dynamics for improved surface quality

The cutter’s three‑flute geometry with an unequal helix and a dedicated neck relief reduces harmonic excitation and dampens vibration during slotting operations. A 45° protective chamfer of 0.3 mm and the centre‑cut capability provide secure plunging and safer entry into the workpiece, while the right‑hand cutting direction optimises chip evacuation. These features combine to produce improved surface finish and dimensional stability, which is especially beneficial when alternating between roughing and finishing passes.

Broad material suitability and machine compatibility

Engineered as a universal tool, the cutter is suitable for steel, stainless steel (INOX), cast iron, ductile iron, Cr‑Ni alloys, non‑ferrous metals and aluminium with silicon content, as well as many abrasive and special alloys. The standardised cylindrical shank to DIN 6535 HB with a 20 mm shank diameter and h6 tolerance ensures precise clamping and compatibility with a wide range of toolholders. As a result, workshop inventory is simplified: one versatile cutter covers plunge cutting, slotting and light face‑milling tasks across varied materials, supporting efficient production planning.
