Meet the Dormer Pramet C407 8.0 mm HSS-E Powder Metallurgical End Mill with Weldon shank—a robust roughing tool designed for high-efficiency material removal in steel and stainless steels. Built for shoulder milling, slot milling, and ramping, it handles tough workpieces with consistent performance in production environments.

• Diameter: 8.0 mm
• Length of Cut: 19 mm
• Overall Length: 69 mm
• Shank: Weldon 10 mm
• Material: HSS-E, powder metallurgical (Primax) with bright finish
• Flutes: 4
• Profile: NRA asymmetrical coarse pitch
• Helix: 35°
• Rake Angle: 12°
• Standards: DIN 844 K
• Applications: Shoulder milling, slot milling, and ramping
• Suitable Materials: Steel, cast steel, ferritic, martensitic and super-austenitic stainless steels, duplex or precipitation hardening stainless steels, cast iron, copper and copper alloys, and high-temperature alloys

The NRA asymmetrical coarse pitch and four-flute geometry optimize chip evacuation and cutting force distribution, enabling steadier feeds and faster material removal during roughing. The powder-metallurgical HSS‑E core combines hardness and toughness for longer tool life in demanding alloys, while the bright finish aids heat dissipation and smooth cutting action. DIN 844 K compatibility ensures reliable interchangeability with standard holders and existing tooling setups, reducing setup time and improving consistency across jobs.
