The tool’s 30° helix promotes smooth cutting and efficient chip evacuation, reducing built-up edge in demanding slots. The TiCN coating enhances wear resistance, helping maintain edge integrity across multiple passes. With a compact 73 mm overall length and 27.5 mm reach, it delivers solid rigidity in confined spaces while still providing enough reach for deeper slot operations. The 12 mm Weldon shank ensures secure clamping in standard milling holders, supporting consistent repeatability in production environments. This combination makes it a dependable choice for precise slotting and shoulder milling across a range of common engineering materials.
