• Overall Length: 52 mm
• Radius: 2.5 mm (full profile)
• Shank: 6 mm Weldon shank with flatted section for positive drive
• Material: HSS-E (cobalt-based high-speed steel) with bright finish
• Helix Angle: 30°
• Rake Angle: 12°
• Standard: DIN 327 D
• Application: Copy milling in free machining steel and copper or copper alloys

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.
