Experience precise, smooth contours in constrained pockets thanks to the extra-short geometry and a gentle 2.5 mm radius that produces clean, accurate radii. The cobalt-enriched HSS-E core delivers improved wear resistance and edge retention under demanding copy milling conditions, while the 30° helix and 12° rake optimize chip evacuation and reduce edge build-up on non-ferrous materials. The flatted 6 mm Weldon shank provides secure clamping and minimizes runout on compact milling setups, helping you maintain consistent depth and finish across multiple passes. With its DIN 327 D compatibility, this end mill fits standard holders and delivers reliable interchangeability for repeatable results across steel and copper alloy profiles.
