Dormer Pramet C299 5.0mm HSS-E-Powder Metal Flatted Shank End Mill Multi-Flute Standard Length End Mill DIN 844 K

The Dormer Pramet C299 5.0mm HSS-E-Powder Metall End Mill is a compact, high-precision cutter built for shoulder milling, slot milling, and ramping. Designed for machinists who need consistent performance in a range of steels and alloys, it combines a 5 mm diameter with a robust 6 mm Weldon shank and DIN 844 K compatibility.

• Diameter: 5.0 mm
• Length of cut: 13 mm
• Overall length: 57 mm
• Shank: Weldon shank, 6 mm
• Flutes: 3-flute short series design
• Material: Powder-metallurgical HSS-E with bright finish
• Helix: 45°
• Rake angle: 12° (optimized for shoulder milling, slot milling and ramping)
• Standards: DIN 844 K
• Applications: Effective for plain carbon steel, alloy steel, tool steel, ferritic, martensitic and super‑austenitic stainless steels, duplex or precipitation hardening stainless steel, cast iron, copper and copper alloys, and high‑temperature alloys

The C299 end mill leverages a powder-metallurgical HSS-E substrate to deliver improved wear resistance and edge retention, which translates to longer tool life under demanding cutting conditions. Its 3-flute geometry provides efficient material removal while supporting a clean surface finish, making it versatile for both light finishing and moderate stock removal. The 45° helix reduces cutting forces and enhances chip evacuation, while the 12° rake angle supports smooth entering cuts in shoulder milling and ramping operations. The 6 mm Weldon shank ensures secure clamping in standard tool holders, minimizing runout and vibration for dependable, repeatable results across multiple jobs.
