Designed for reliable keyway milling, the cobalt-based HSS‑E alloy enhances wear resistance and tool life when cutting through tough materials. The combi shank with Weldon flat and threaded section ensures secure clamping and accurate depth control, reducing runout for cleaner slots. With a 10° helix and 10° rake, the cutter promotes smooth chip flow and a high-quality finish, minimizing burr formation in precision keyways. This tool is ideal for production environments and machining tasks that require consistent geometry in shafts, gears, and other keyway-bearing components.
