Introducing the Dormer Pramet C299 10.0 mm HSS-E powder-metallurgical end mill — a compact, four-flute cutter designed for shoulder milling, slot milling, and ramping in a wide range of steels and alloys. Equipped with a flatted 10 mm Weldon shank and DIN 844 K compatibility, this standard-length end mill delivers reliable clamping and consistent performance in demanding machining tasks.

• Diameter: 10.0 mm
• Flutes: 4-flute geometry for efficient chip evacuation and stable cutting
• Material: HSS-E with powder metallurgy and bright finish for improved wear resistance
• Shank: Flatted 10 mm Weldon shank for secure seating and repeatable seating in holders
• Length and reach: Length of cut 22 mm; overall length 72 mm; reach 31.5 mm with neck relief
• Standard: DIN 844 K compatibility for broad tool holder interchangeability
• Geometry: 45° helix and 12° rake angle optimized for shoulder, slot milling and ramping
• Applications: Suitable for plain carbon steel, alloy steel, tool steel, ferritic/martensitic and super-austenitic stainless steels, duplex stainless steel, precipitation hardening stainless steel, cast iron, copper and copper alloys, and high-temperature alloys
• Finish: Bright finish reduces friction and supports clean cuts

The design prioritizes efficient material removal and stable performance across a broad material spectrum. Four flutes offer steady chip flow in deeper pockets, while the generous reach and neck relief minimize rubbing during shoulder milling. The combination of powder-metallurgical HSS-E and a robust Weldon shank provides a balance of hardness, toughness, and build quality you can rely on in everyday workshop milling. Ideal for machines and operators performing pocketing, ramping, and finishing passes in both steel and stainless materials, as well as ductile iron and copper alloys.
