Dormer Pramet C299 3.0mm HSS-E-Powder Metal Flatted Shank End Mill Multi-Flute Standard Length End Mill DIN 844 K

Introducing the Dormer Pramet C299 3.0 mm HSS-E powder metallurgy end mill. This short-series, three-flute cutter is crafted for precise milling in tight spaces, ideal for shoulder milling, slot milling, and ramping across a wide range of steels and alloys.

• Diameter: 3.0 mm
• Number of flutes: 3-flute design for efficient cutting at small diameters
• Length of cut: 8 mm
• Overall length: 52 mm
• Shank: 6 mm Weldon flat shank (flatted) for improved grip and reduced slip
• Material: Powder metallurgical HSS-E with a bright finish for enhanced wear resistance
• Helix angle: 45° for efficient chip evacuation and smooth cutting
• Rake angle: 12° to minimize built-up edge during shoulder milling and ramping
• DIN standard: DIN 844 K
• Applications: Shoulder milling, slot milling, and ramping in a variety of workpieces
• Materials compatibility: Plain carbon steel, alloy steel, tool steel, ferritic/martensitic and super‑austenitic stainless steels, duplex or precipitation-hardening stainless steels, cast iron, copper and copper alloys, and high-temperature alloys

Engineered for reliability, the C299 combines the toughness of HSS-E with powder metallurgy to deliver consistent performance across demanding milling tasks. The 3-flute geometry and 45° helix optimize chip control and finish, while the 12° rake angle helps maintain a clean cutting action even in harder alloys. The compact 52 mm overall length and rigid Weldon flat shank provide stiffness in confined pockets, reducing deflection during intricate shoulder and slot milling operations. This end mill is a versatile choice for precision machining, prototyping, and small-batch production where accuracy and surface finish matter.
