With its cobalt-enriched HSS-E composition and bright finish, this Woodruff cutter provides enhanced wear resistance and toughness for demanding milling tasks. The 10° helix and 10° rake angle optimize chip formation and reduce cutting forces, supporting smoother entry and a cleaner finish across a range of metals. The DIN 850-compliant design and screwed combi shank ensure secure mounting on compatible machines, minimizing runout and tool movement during keyway milling. Ideal for automotive, aerospace, manufacturing, and general metalworking where precise, repeatable keyways and slots are required.
