This 8 mm, 3-flute slot drill from Dormer Pramet is engineered for precise slotting, shoulder milling, and ramping in a range of metals. With a powder-metallurgical HSS-E body and the Alcrona Primax coating, it’s built for reliable performance and longer tool life in everyday milling tasks.

• Diameter: 8.0 mm
• Flutes: 3-flute design for stable cutting and efficient chip evacuation
• Length of cut: 19 mm
• Overall length: 69 mm
• Shank: 10 mm Weldon shank with flatted shank geometry
• DIN standard: DIN 844 K
• Material and coating: HSS-E, powder-metallurgical, Alcrona Primax coating
• Helix and rake: 30° helix and 12° rake angle for efficient cutting and chip control
• Recommended uses: Slot milling, shoulder milling, and ramping in steel, cast steel, cast iron, copper and copper alloys, and titanium and titanium alloys

The combination of a 30° helix and 12° rake angle reduces cutting forces and promotes smooth chip flow, helping you achieve clean shoulders and precise slots even in harder materials. The Alcrona Primax coating minimizes built-up edge and heat generation, extending tool life in demanding milling cycles. With a DIN 844 K shank and a robust 69 mm overall length, this drill fits standard holders and delivers repeatable results for a wide range of steel and non-ferrous alloys.
