Designed to deliver clean slots and consistent dimensions, the C367 excels in demanding metalworking tasks. The powder metallurgical HSS‑E core paired with the Alcrona Primax coating provides strong wear resistance and reliable performance under both dry and coolant-assisted cutting. The 40° helix promotes efficient chip evacuation and smoother cutting action, while the 15° rake angle helps minimize burr formation on shoulder and slot surfaces. With a compact form and a 12 mm Weldon shank, it fits standard holders and tools for versatile integration into existing setups. The result is precise slotting, dependable ramping, and durable performance across steel and aluminum workpieces.
