The Dormer Pramet C367 3.0mm slot drill is a compact, high-precision tool designed for shoulder milling, slot milling and ramping in metalworking. Built for tight tolerances and reliability, it’s ideal for machinists tackling small-diameter slots in steel and aluminum.

• Diameter: 3.0 mm
• Length of cut: 5 mm
• Overall length: 49 mm
• Shank: 6 mm Weldon
• Flutes: 3-flute configuration for efficient slotting
• Material and coating: HSS-E powder metallurgical with Alcrona Primax coating
• Helix and rake: 40° helix, 15° rake angle
• Standard: DIN 327 D
• Applications: Shoulder milling, slot milling and ramping in free-machining steel, stainless steel and wrought aluminium

With a short, rigid geometry and a Weldon shank, this tool minimizes deflection in confined spaces while delivering consistent hole and slot dimensions. The 3-flute design supports effective chip evacuation and smoother finishes on slots and shoulders. The Alcrona Primax coating enhances wear resistance, helping to extend tool life in challenging materials without sacrificing precision. Designed for DIN 327 D compatibility, it delivers reliable performance across common machining scenarios in steel and aluminum.
