The Dormer Pramet C306 6.0mm HSS-E-Powder Metal Primax Flatted Shank 3 Flute Short Series Slot Drill is a compact, high-precision tool designed for precise slotting, shoulder milling, and ramping in small pockets and tight spaces. Built for free-machining steel and copper alloys, it combines reliability with efficient chip control.

• Diameter: 6.0 mm
• Flutes: 3-flute design for consistent chip evacuation and stable cutting
• Length of cut: 8 mm
• Overall length: 52 mm
• Shank: 6 mm Weldon/flat shank for secure driving and reduced slip
• Material: HSS‑E powder metallurgy with bright finish for enhanced hardness and wear resistance
• Helix angle: 30° for smooth entry and effective chip flow
• Rake angle: 12° to improve cutting action on shoulders
• Standard: DIN 327 D
• Applications: Shoulder milling, slot milling, and ramping in free machining and plain carbon steels and copper/copper alloys

Designed to deliver precise, clean slots in restricted geometries, this slot drill minimizes deflection in tight pockets while maintaining a consistent wall finish. The powder-metallurgy HSS‑E construction extends tool life under typical cutting speeds and feeds, making it a dependable choice for daily machining tasks. Its compact length and robust shank geometry provide solid rigidity, enabling accurate plunges, plunging slots, and controlled ramping in a single setup.
