The TiCN coating reduces friction and enhances wear resistance, helping produce cleaner slots and smoother finishes even in tougher metals. The powder-metallurgical HSS-E core provides toughness and stable performance across repeated passes, while the 30° helix and 12° rake angle optimize cutting action for efficient chip formation and steady engagement. A secure Weldon 6 mm shank ensures reliable clamping for repeatable depth control, and the tool’s geometry supports efficient chip evacuation in narrow slots and shallow pockets. Ideal for shops performing light to mid-depth slotting and shoulder milling in steel, cast iron, copper alloys, and titanium alloys, the C139 offers a dependable, single-tool solution for standard DIN 844 K holders.
