This tool excels where precision and stability matter most. The three-flute design provides steady chip flow and a smooth cutting action across the workpiece, helping achieve straight walls and accurate slot dimensions even in hardened or heat-treated steels. The powder-metallurgical HSS-E core combines toughness with a sharp edge, while the Alcrona Primax coating reduces wear, minimizes built-up edge, and improves heat resistance for longer tool life in challenging alloys. The Weldon 12 mm shank with a flat section ensures a secure grip in standard holders, minimizing runout during high-speed slotting and ramping. With its DIN 327 D specification, it fits seamlessly into established tooling ecosystems, enabling reliable interchangeability across machines and setups.
