The Dormer Pramet C246 3.0 mm end mill is a compact, 4-flute cutting tool designed for precision work in tight spaces. Ideal for shoulder milling, slot milling, and ramping, it delivers reliable performance across a range of common engineering materials.

• Diameter: 3.0 mm
• Flutes: 4-flute design for balanced cutting and efficient chip evacuation
• Length of cut: 8 mm
• Overall length: 52 mm
• Shank: Weldon 6 mm
• Material: Powder-metallurgical HSS-E core
• Coating: TiCN coating for enhanced wear resistance
• Helix angle: 30°
• Rake angle: 12° (optimized for shoulder milling)
• Standard: DIN 844 K
• Applications: Shoulder milling, slot milling, ramping in free-machining, plain carbon and alloy steel, cast-iron, copper or copper alloys, and titanium or titanium alloys

The combination of a powder-metallurgical HSS-E substrate with a TiCN coating delivers a tough, wear-resistant cutting edge that maintains sharpness through repeated passes. The 30° helix helps with efficient chip formation and smoother surface finishes, while the 12° rake angle supports controlled cutting forces during shoulder milling and ramping. With a Weldon 6 mm shank, this end mill offers secure retention in standard tool holders, making it a dependable choice for high-precision machining in CNC setups. This tool is well-suited for free-machining steels, cast iron, copper alloys, and titanium alloys, providing consistent performance across a broad material spectrum.
