This tool pairings a robust HSS-E substrate with a wear-resistant Alcrona Primax coating, optimized for demanding profiles and slotting tasks. The 3-flute geometry supports efficient chip evacuation in slot milling, while the short length of cut minimizes deflection for precision pockets. The Weldon 6 mm shank and flatted section provide a secure, repeatable grip in standard tool holders, making it a reliable choice for quality-focused workshops working with a range of metals—from common steels to titanium alloys.
