The Dormer Pramet C123 3/8" HSS-E powder metallurgy slot drill is a precise, two-flute tool designed for slot milling, shoulder milling, and ramping in steel, cast steel, and copper alloys. Built to perform in standard DIN 844 K holders, it combines reliability with efficient cutting for everyday workshop use.

• Diameter: 3/8" (9.525 mm) slot drill for accurate slots and pockets
• Shank: Flatted Weldon shank, 10 mm, for secure seating and repeatable performance
• Material and finish: HSS-E with a powder metallurgy composition and a bright finish for wear resistance
• Flutes: 2-flute geometry engineered for smooth cutting and effective chip evacuation
• Length and reach: Length of cut 22 mm; overall length 72 mm; reach 31.5 mm with neck relief
• Geometry: 30° helix and 12° rake angle to optimize cutting action in shoulders, slots, and ramps
• Standard: DIN 844 K compatibility for reliable tool-holder fit
• Applications: Suitable for slot milling, shoulder milling, and ramping in steel, cast steel, and copper/copper alloys

This tool delivers consistent performance across common milling tasks: the flatted shank reduces slip in the holder, the two-flute design eases chip removal, and the powder-metallurgy HSS-E construction delivers enhanced wear resistance for longer tool life. With its compact reach and proven DIN standard, it’s a practical choice for machinists seeking dependable slots, clean shoulders, and efficient ramping in a range of metallic materials.
