The Dormer Pramet C247 11.0 mm HSS-E powder-metallurgical end mill is a robust four-flute cutting tool designed for shoulder milling, slot milling, and ramping. With a DIN 844 K flatted shank and a 79 mm overall length, it delivers reliable performance in demanding milling tasks.

• Diameter: 11.0 mm
• Flutes: 4
• Length of Cut: 22 mm
• Overall Length: 79 mm
• Shank: Weldon (flatted), 12 mm
• Standard: DIN 844 K
• Material: Powder-metallurgical HSS-E with bright finish
• Helix: 30°

• Applications: Shoulder milling, slot milling, and ramping
• Compatible Materials: Free-machining steels, plain carbon steels, copper and copper alloys

The powder-metallurgical HSS-E core combines hardness and toughness for extended tool life, even in challenging milling environments. The 30° helix promotes efficient chip formation and steady cutting, while the 12° rake angle supports clean shoulders and precise slots. The Weldon-flatted 12 mm shank ensures reliable seating and repeatable clamping in standard collet systems, making setup quick and predictable. This end mill is well-suited for shops that require a versatile tool capable of handling shoulder, slot, and ramp operations in common engineering steels and copper-based materials.
