The Dormer Pramet C247 5/8 Inch HSS-E-Powder Metall Flatted Shank End Mill is a compact, four-flute milling tool designed for shoulder milling, slot milling, and ramping in free-machining and plain carbon steels as well as copper and copper alloys. Built on a DIN 844 K standard, it pairs a sturdy Weldon flat shank with a robust powder-metallurgical HSS-E core for reliable performance in everyday CNC milling tasks.

• Diameter: 5/8 inch (15.875 mm)
• Flutes: 4-flute configuration for efficient chip evacuation and smooth cutting
• Material: Powder-metallurgical HSS-E for enhanced toughness and wear resistance
• Shank: Flatted Weldon shank (16 mm) for secure clamping and precise transmission of cutting forces
• Finish: Bright finish for reduced built-up edge and easier inspection
• Length of cut (LOC): 32 mm, suitable for deep but controlled material removal
• Overall length: 92 mm with 43.5 mm neck relief reach
• DIN standard: DIN 844 K compatibility for standard tooling interfaces
• Helix angle: 30° for efficient chip formation and smooth cuts
• Rake angle: 12° to support shoulder milling and ramping operations
• Applications: Shoulder milling, slot milling, and ramping in a range of materials

Benefit from predictable, stable milling performance across common shop materials. The 30° helix and 12° rake promote clean chip formation and steady cutting forces, while the 32 mm length of cut and 43.5 mm reach with neck relief enable controlled depth operations without sacrificing rigidity. The combination of powder-metallurgical HSS-E and a bright finish delivers a durable edge with reliable wear resistance, helping extend tool life in free-machining steels and copper alloys. The standard DIN 844 K shank makes it easy to pair with compatible holders and fixtures, and the Weldon flat ensures solid clamping to minimize slippage during heavier cuts. This end mill is well-suited for shops that need a single, versatile tool for shoulder milling, slot milling, and ramping on a mix of common engineering materials.
