With its 1-tooth geometry, this Woodruff cutter delivers clean, predictable chip formation and precise keyway slots, minimizing burrs and reducing finishing passes. The cobalt-based HSS-E composition provides enhanced wear resistance and toughness for demanding materials, including stainless steels and high-temperature alloys. A 10° helix and 10° rake angle optimize cutting forces and chip evacuation, promoting smoother operation and stable feeds. The 10 mm combi shank with Weldon flat and threading secures reliable seating in compatible holders, supporting stable milling even at higher feeds. DIN 850 compliance ensures compatibility with standard toolholders, making integration into existing setups straightforward. This tool is ideal for gear keys, pulleys, and shaft keyways where accurate, consistent results matter.
