12mm Corner Radius Milling Cutter DIN 6527K Type N Solid Carbide TiAlN Coating, 45° Chamfer - TECWERK

Benefit from a combination of precision, durability and low-vibration performance thanks to the TiAlN coating and solid carbide construction; ideal for both roughing and finishing. Order the cutter directly via Metav Werkzeuge or contact the consultants for application advice.

TECWERK 12 mm solid carbide TiAlN slot drill (DIN 6527 K) — three-flute, short design

The TECWERK 12 mm slot drill is a short, three-flute, centre-cut tool designed for low-vibration slotting and plunge operations in a wide range of metals

• Solid carbide VHM with TiAlN coating
• DIN 6527 K three-flute short cutter
• Centre-cut for plunging and milling
• Cylindrical shank per DIN 6535 HB h6

Accurate cutting for consistent production results

The TiAlN coating combined with solid carbide substrate provides a hard, heat-resistant cutting surface that sustains cutting performance under elevated temperatures. This results in longer tool life and more consistent component tolerances, reducing the need for frequent tool changes and supporting continuous production. The short design and three-flute geometry offer a balance between chip evacuation and rigidity, which helps to maintain surface quality during both roughing and finishing passes.

Versatile material compatibility reduces setup time

Designed with a universal geometry, the cutter is suitable for machining a broad spectrum of materials — including steel, stainless steels (INOX), cast irons, non-ferrous metals and aluminium alloys with silicon content. The tool’s centre-cutting capability enables direct plunging, so one tool can perform slotting and plunge operations that might otherwise require multiple tools. This versatility shortens setup time and simplifies tool inventories on the shop floor.

Geometry and relief deliver vibration‑reduced machining

The unequal pitch and neck relief features minimise harmonic excitation and chatter, producing quieter, more stable cutting conditions. A 45° chamfer and small protective chamfer (0.2 mm) at the cutting edge reduce edge chipping at entry, improving edge life during interrupted cuts. Together with the TiAlN surface, the geometry supports effective heat management and reliable chip formation, which directly improves part quality and process stability.

Shank and tolerance for secure toolholding

The cutter is supplied with a cylindrical shank per DIN 6535 HB and a shaft tolerance of h6, ensuring a precise fit in standard collets and toolholders. This precise shank control reduces runout, which is crucial for maintaining dimensional accuracy and extending the lifetime of both tool and spindle bearings. The effective length and neck relief facilitate clearance in tight setups while preserving stiffness for accurate milling.
