Dormer Pramet C11 3.0mm HSS-E-Powder Metal Flatted Shank 2 Flute Short Series Slot Drill DIN 327 D

Precision-focused slot drill built for tight pockets, the Dormer Pramet C11 3.0 mm slot drill is ideal for engineers and machinists performing shoulder milling, slot milling, and ramping in free-machining steel and copper alloys. Its extra-short profile and robust Weldon shank deliver reliable, repeatable results in compact workzones.

• Diameter: 3.0 mm
• Length of cut: 5 mm
• Overall length: 49 mm
• Shank type: 6 mm Weldon shank (DIN 327 D)
• Material & finish: HSS-E powder metallurgical with bright finish
• Helix & rake: 30° helix with 12° rake angle for efficient cutting and chip formation
• Flutes: 2-flute configuration for balanced rigidity and material removal
• Applications: Shoulder milling, slot milling, and ramping in free-machining steel and copper alloys

In practical use, this tool delivers clean, accurate slots with minimal deflection thanks to its short length and rigid Weldon shank. The powder-metallurgy HSS-E composition provides improved wear resistance and edge retention for longer tool life in challenging metals. The DIN 327 D standard ensures consistent fit in compatible holders, enabling repeatable performance across setups. Whether you’re pocketing tight spaces, milling precise slots, or ramping into a workpiece, the C11 slot drill helps you achieve reliable, high-quality finishes with fewer passes.
