The Dormer Pramet C126 2.5mm slot drill is an extra-short, 2-flute cutting tool with a TiCN-coated HSS-E substrate designed for precise slotting, shoulder milling, and ramping in tight pockets. Built for accuracy and reliability, it’s ideal for machinists working in small-diameter operations across a range of materials.

• Diameter: 2.5 mm
• Length of cut: 5 mm
• Overall length: 49 mm
• Shank: Flatted 6 mm Weldon shank for secure seating and reduced slip
• Material and coating: HSS-E with TiCN coating, produced via powder metallurgy for enhanced toughness and wear resistance
• Helix and rake: 30° helix and 12° rake to optimize cutting action and chip evacuation
• Standard: DIN 327 D compatible geometry for standardized tooling fits
• Applications: Shoulder milling, slot milling, and ramping in free-machining steels, plain carbon and alloy steels, cast iron, copper alloys, and titanium alloys

This tool combines a rigid short design with a resilient TiCN-coated HSS-E core, delivering clean slots and smooth entrances in challenging materials. The 2-flute geometry supports efficient chip clearance in narrow slots, while the powder-metallurgy substrate provides a balanced mix of hardness and toughness to reduce wear and extend tool life. Compatible with standard collets and holders thanks to the robust Weldon-style shank, it’s a dependable choice for finishing tight pockets and precise features without sacrificing rigidity.
