Slot drill DIN 6527L Type N – Ø 4 mm, cutting length 12 mm (solid carbide, TiAlN) by TECWERK

A Slot drill DIN 6527L Type N engineered as a long two‑flute cutter for vibration‑reduced slotting, plunging and finishing across steels and non‑ferrous alloys

• Solid carbide (VHM) with TiAlN coating
• Two‑flute long design with centre cutting
• 45° protective chamfer for edge durability
• Suitable for steels, cast iron and non‑ferrous

High‑temperature stability and extended tool life for continuous production

The combination of solid carbide fine‑grain substrate and TiAlN coating delivers high thermal and abrasive resistance, which translates into extended tool life during sustained machining cycles. The TiAlN layer forms a protective oxide at elevated temperatures, improving edge stability during dry or high‑heat operations. This results in fewer tool changes and more predictable process windows, supporting efficient cycle times and consistent component quality.

Geometry designed to cut smoothly and reduce vibration

A long two‑flute layout with centre cutting capability and a dynamic pitch counters harmonic excitation to produce more stable cutting conditions. The cutter’s 45° protective chamfer and neck relief reduce chipping at the cutting edge and enable secure plunge starts, while the cylinder shank to DIN 6535 HB with tolerance h6 ensures concentric clamping in standard toolholders. These features combine to deliver reliable performance for both roughing and finishing operations, with measurable reductions in chatter and improved surface integrity.

Versatile material suitability and application benefits

The tool is designed for universal use across a broad material spectrum: high‑strength steels, cast iron variants, stainless steels (INOX), non‑ferrous alloys and aluminium alloys containing silicon, as well as certain abrasive and special alloys. Its balanced geometry makes it suitable for both aggressive material removal and fine finishing passes, reducing the need for multiple dedicated cutters and optimising tool inventory. For machining centres and jobbing shops that demand consistent accuracy, the cutter’s construction supports repeatable results and longer tool intervals.
