The Dormer Pramet C246 is a robust 20 mm diameter, 4-flute end mill designed for shoulder milling, slot milling, and ramping in a wide range of metals. Built on HSS-E powder metallurgy with a TiCN coating and a flatted 20 mm Weldon shank, it delivers reliable performance in free-machining steels, cast iron, copper alloys, and titanium alloys.

Designed to handle demanding milling tasks, the C246 combines toughness and precision. The powder-metallurgical HSS-E core provides reliable edge retention and impact resistance, while the TiCN coating reduces friction and heat buildup during cutting. The 30° helix promotes efficient chip evacuation and smooth entry into cuts, helping to minimize vibration and improve surface finish. The 12° rake angle further enhances stability during shoulder milling and ramping, making this end mill a versatile choice for deep pockets and complex pocketing work.
