The Dormer Pramet C367 2.0 mm HSS-E-Powder Metall Alcrona Primax Flat Shank 3-Flute Short Series Slot Drill is a precision micro-slotting tool designed for shoulder milling, slot milling and ramping in metalworking applications. Built for tight tolerances and reliable performance, it’s ideal for engineers and machinists working with small-diameter slots in steel and aluminum.

• Diameter: 2.0 mm
• Length of cut: 4 mm
• Overall length: 48 mm
• Shank: Weldon, 6 mm (flat shank for secure seating and anti-rotation guidance)
• Material and coating: HSS-E powder metallurgy with Alcrona Primax coating for wear resistance and reduced friction
• Flutes: 3-flute configuration (extra short series) for efficient chip evacuation in narrow slots
• Helix angle: 40° to promote smooth cutting in soft and hard metals
• Rake angle: 15° to enhance cutting action during shoulder milling and ramping
• DIN standard: DIN 327 D compatibility for interchangeability with standard holders
• Applications: Shoulder milling, slot milling, and ramping in free machining steel, stainless steel, and wrought aluminium

This combination of geometry and coating delivers precise slot dimensions, clean bottoms, and consistent surface finishes in tight tolerances. The extra-short length reduces tool deflection and chatter on small-diameter slots, while the Weldon shank ensures dependable clamping and alignment. The Alcrona Primax coating lowers friction and heat buildup, extending tool life in demanding materials and repetitive cycles. Ideal for micro-slot work in compact assemblies, electronics housings, and automotive components where accurate 2 mm slots are required.
