High-Performance Solid Carbide Finishing Mill
This 6-flute solid carbide end mill is aimed at professional finishing applications requiring high precision. The non-centre cutting geometry and rigid cylindrical shaft make it a reliable choice for peripheral machining tasks. A 45° helix angle enables a smooth, low-vibration cutting action, which significantly contributes to an excellent surface finish on the workpiece. Equipped with the RT405 high-performance grade and TiAlN coating, this tool withstands thermal stress and delivers consistent performance across various metals.

Applications

This cutter is primarily designed for accurate finishing operations on industrial workpieces. Thanks to its 6 flutes and 45° helix angle, it is particularly suitable for shoulder milling and contouring where superior surface smoothness is required. It reliably handles tasks in steel, stainless steel, and cast iron, supporting efficient production processes.
Special features
The advanced TiAlN coating (RT405) protects the solid carbide substrate against premature wear and heat generation, creating ideal conditions for consistent finishing results. The combination of a high flute count and a 45° helix angle minimizes tool vibration and chatter, enabling the reliable manufacturing of workpieces with an outstanding surface finish.
