Engineered for precision milling in confined spaces, the Dormer Pramet C907 4.0 mm HSS-E-Powder Metallurgical End Mill is a compact, three-flute tool designed for shoulder milling, slot milling, and ramping across a broad range of materials.

• Diameter: 4.0 mm
• Length of cut: 11 mm
• Overall length: 55 mm
• Shank: 6 mm Weldon shank with a flatted section for secure drive
• Material and coating: Powder-metallurgically produced HSS-E with Alcrona Primax coating for enhanced wear resistance
• Flutes and geometry: 3 flutes, 45° helix, 12° rake angle
• Standards: DIN 844 K compliant, Short-series end mill
• Applications: Shoulder milling, slot milling, and ramping in plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper/copper alloys, and high-temperature alloys

This end mill’s combination of powder metallurgical HSS-E and Alcrona Primax coating delivers wear resistance and reliable performance in tough materials, while the 3-flute design provides efficient chip removal and a good balance between rigidity and finish quality. The Weldon shank with a flat ensures secure clamping for repeatable accuracy, making it suitable for precision work in constrained pockets and tight milling scenarios.
