Dormer Pramet C11 7/16 Inch HSS-E-Powder Metal Flatted Shank 2 Flute Short Series Slot Drill DIN 327 D

The Dormer Pramet C11 7/16 Inch HSS-E-Powder Metall Slot Drill is a compact, two-flute tool designed for precise slot milling, shoulder milling, and ramping in tight workspaces. Built for reliability in free-machining steel and copper alloys, it delivers consistent performance in challenging setups.

• Diameter: 7/16" (≈11.1 mm) slot drill for precise, narrow slots
• Length of cut: 13 mm, optimized for shallow to mid-depth slots
• Overall length: 70 mm, providing reach in restricted cavities
• Shank: Weldon 12 mm for secure, repeatable clamping
• Material: HSS-E powder metallurgical with a bright finish for improved wear resistance and toughness
• Flutes: 2-flute geometry designed for efficient chip evacuation in slot and shoulder milling
• Helix angle: 30° to promote smooth cutting and effective chip control
• Rake angle: 12° to enhance cutting action in a range of materials
• Standard: DIN 327 D, ensuring compatibility with standard tooling setups
• Applications: Shoulder milling, slot milling, and ramping in free-machining steel and copper/copper alloys

This tooling configuration—short series length, robust HSS-E powder metallurgy, and a bright finish—delivers reliable slotting performance in constrained stations. The 2-flute design reduces chatter and produces clean edges, making it suitable for precise slot dimensions and repeatable results across multiple passes. Ideal for machinists who need a durable, interchangeable drill that fits compact machines and tight pockets without compromising on slot quality or edge finish.
