The Dormer Pramet C353 9.0mm HSS-E-Powder Metall Alcrona Primax slot drill is a compact, high-precision cutting tool designed for precise slotting, shoulder milling, and ramping in a range of metals. Built for reliability in confined spaces, it delivers clean slots with consistent wall quality in steel, cast iron, copper alloys, and titanium alloys.

• Diameter: 9.0 mm
• Flutes: 3, short series for rigidity in tight pockets
• Length of cut: 11 mm
• Overall length: 61 mm
• Shank: Weldon, 10 mm for secure toolholding
• Material & coating: HSS-E with powder metallurgy core and Alcrona coating for improved wear resistance
• Helix & rake: 30° helix and 12° rake angle to optimize cutting action and chip formation
• Standard: DIN 327 D compatibility for broad toolholder interchangeability
• Primary applications: shoulder milling, slot milling, and ramping in a variety of metals
• Materials suited: steel and cast steel, cast iron, copper/copper alloys, and titanium/titanium alloys

Designed to perform in restricted workspaces, this tool combines a robust HSS-E substrate with a durable Alcrona coating to extend tool life while delivering smooth, accurate slots. The extra-short geometry minimizes flex in tight cavities, helping maintain precise wall finishes. Ideal for precision engineers who need reliable slotting and shoulder milling in steel, aluminum, and high-hardness alloys without frequent tool changes.
