• Applications: Keyway milling in steel, stainless steel, cast iron, non‑ferrous metals, and high‑temperature alloys

This tool is optimized for reliability in demanding materials, delivering precise keyways on shafts, gears, and mating components. The cobalt-enhanced HSS‑E construction provides superior wear resistance and hot hardness, helping maintain edge retention during extended milling sessions. The 10° helix and 10° rake improve cutting action and chip evacuation, reducing heat generation and ensuring smoother, more consistent passes. A Weldon flat combined with a threaded end on the 6 mm combi shank provides secure clamping and minimal runout in both CNC and manual milling setups, enabling repeatable results across multiple operations. Designed to DIN 850 standards, it fits standard tool holders for straightforward integration into existing workflows.
