Description
The Dormer Pramet R520 is a 3/8 inch carbide stub drill with a DIN 6539 straight shank, designed for precise metal drilling across a wide range of materials. It delivers clean, accurate holes with consistent performance suitable for professional shops, maintenance teams, and serious hobbyists alike.
Equipped with a 130-degree point for self-centering and reduced push force, a Titanium Nitride (TiN) coating to extend tool life and improve performance on harder materials, and convex cutting edges that break chips smoothly, this drill is built for high-speed, high-feed drilling while maintaining reliable hole quality (h8 tolerance) across steel, aluminum, and stainless steel.
- 130° point for self-centering and reduced push force: promotes easy hole entry and accurate starting position, lowering operator effort and improving first-pass success.
- TiN coating for longer service life: reduces wear and friction, delivering longer tool life and better performance when drilling harder or tougher materials.
- Convex cutting edges for efficient chip control: enables higher cutting speeds and feeds with smoother chip breakdown and reliable chip evacuation for steadier drilling progress.
This high-performance drill combines premium carbide with a robust straight-shank DIN 6539 design to provide dependable, repeatable results. Whether you’re drilling automotive steel, aluminum components, or stainless parts, you’ll benefit from consistent hole quality, reduced downtime, and the confidence that comes from using a trusted, precision-engineered tool.
