The Dormer Pramet C948 is a long-series roughing end mill designed for deep-pocket and shoulder/slot milling. With a 14 mm diameter, NRA asymmetrical coarse pitch profile, and four flutes, it delivers aggressive material removal while maintaining stability across tough workpieces. Built on powder-metallurgical HSS-E and coated with Alcrona Primax, it combines toughness with wear resistance for demanding milling applications.

• Diameter: 14.0 mm
• Flutes: 4-flute NRA asymmetrical coarse pitch design
• Length of cut: 53 mm length of cut (DOC) for efficient roughing
• Overall reach: 110 mm overall length with 64.5 mm reach including neck relief
• Shank: 12 mm Weldon shank for secure clamping
• Material & coating: HSS-E, powder-metallurgical grade with Alcrona Primax coating
• Geometry: 35° helix and 12° rake angle optimized for shoulder and slot milling
• Standard: DIN 844 L compatibility for broad tooling compatibility
• Applications: Suitable for plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys

Designed for versatility in metal removal, the C948 excels in roughing tasks where deep pockets and precise shoulders are required. The long-series length keeps tool interruptions to a minimum, while the robust HSS-E substrate and Alcrona Primax coating extend insert life in demanding materials. Its geometry promotes efficient chip evacuation and stable cutting, helping you achieve productive milling on a wide range of workpieces—from everyday steels to challenging high-temperature alloys—without swapping tools.
