Designed for reliable performance in confined machining cells, this drill maintains rigidity and control through tough materials and narrow slots. The powder-metallurgical HSS-E construction offers enhanced wear resistance and toughness, while the bright finish helps resist built-up edge during extended cutting. The 30° helix promotes smooth chip evacuation, and the 12° rake angle supports efficient cutting action in shoulder and slot milling tasks. With a Weldon 25 mm shank, it pairs with standard toolholders for secure clamping and repeatable accuracy across multiple passes. Ideal for workshops tackling precise internal pockets, grooving, and ramping in free-machining steels and copper alloys, the Dormer Pramet C11 25.0mm slot drill delivers consistent, clean slots and shoulders even in demanding applications.
