Designed to produce clean slots and accurate shoulders in confined spaces, the TiCN coating reduces wear and friction for longer tool life. The powder-metallurgical HSS-E structure offers a robust core that maintains sharpness under cutting loads, while the short, rigid geometry with a Weldon shank minimizes deflection for stable finishes. A 30° helix enhances chip evacuation and cutting efficiency, and the 12° rake angle optimizes performance across a variety of materials, including titanium alloys. This combination makes the C126 ideal for precision milling tasks in pocketing, slotting, and ramping operations, delivering consistent results and reliable productivity across commonly machined materials.
