Dormer Pramet C123 9.5mm slot drill is a compact, precision tool designed for shoulder milling, slot milling, and ramping in steel, cast steel, and copper alloys. Built with HSS-E powder metallurgy and a bright finish, it delivers reliable performance in a DIN 844 K standard with a 10mm Weldon shank.

• Diameter: 9.5 mm
• Length of cut: 19 mm
• Overall length: 69 mm
• Shank: 10 mm Weldon shank for secure seating in standard holders
• Material: HSS-E powder metallurgy for improved hardness and wear resistance
• Finish: Bright finish for easy inspection and reduced friction
• Helix angle: 30° for smoother chip evacuation and stable cutting
• Rake angle: 12° to enhance cutting action in steel and copper alloys
• Standards: DIN 844 K compliance for reliable interchangeability
• Applications: Shoulder milling, slot milling, and ramping in ferrous and non-ferrous materials

This slot drill focuses on delivering predictable, consistent performance in through-slot operations and milling pockets with clean, accurate finishes. The combination of a 30° helix and 12° rake optimizes chip control and cutting action, helping reduce built-up edge and tool wear. The 19 mm length of cut provides enough engagement for efficient slotting, while the 69 mm overall length offers ample reach in tight setups. Ideal for shops seeking a durable, ready-to-use solution that aligns with DIN 844 K tooling standards and common Weldon shank tooling systems.
