Description
The Dormer Pramet R520 is a 7/16 inch diameter carbide drill with a DIN 6539 straight shank, finished with a Titanium Nitride (TiN) coating. Designed for versatile use across steel, aluminum, and stainless steel, this high-performance stub drill features a 130-degree point to help self-center and reduce the push force required to start drilling.
With a TiN coating for extended tool life, it stays sharper longer and maintains cutting performance at higher speeds. The convex cutting edges break chips more efficiently, supporting faster feeds and smoother evacuation for cleaner holes.
- 130° self-centering point: reduces starting resistance and helps holes begin precisely, minimizing wandering during initial contact.
- TiN-coated premium carbide: delivers longer tool life and improved wear resistance, enabling reliable drilling in tougher materials and at higher speeds.
- Convex cutting edges for efficient chip breakup: enhances chip control and allows higher feeds, improving overall cutting efficiency and hole quality.
The R520 7/16" drill combines precision, durability, and versatility to improve your workflow. Its straight DIN 6539 shank fits standard chucks for quick tool changes, while the carbide core and TiN coating work together to deliver consistent, high-quality holes with tight tolerances (H8) across common metals. This makes it a dependable choice for production environments, workshops, and DIY projects alike.
