Description
The Dormer Pramet R520 5/16 Inch carbide stub drill is built for fast, accurate metal drilling. With a 130° point that self-centers and reduces push force, it starts cleanly and stays on target at higher speeds, delivering reliable holes in steel, aluminum, and stainless steel. The TiN coating extends tool life and maintains sharpness when drilling harder materials, while the DIN 6539 straight-shank design provides dependable mounting in standard chucks.
- 130° Self-Centering Point: Guides the drill to start squarely, reduces push force, and minimizes wandering for clean first passes.
- TiN-Coated Premium Carbide: Extends tool life and preserves sharpness when drilling harder materials, delivering consistent performance across steels and aluminum.
- Convex Cutting Edges: Breaks chips smoothly, enabling higher cutting speeds and feeds with steady, repeatable hole quality.
The R520 5/16" carbide stub drill is capable of producing high-quality holes with H8 tolerance at higher speeds and feeds, helping you reduce rework and accelerate production. Its robust carbide core and TiN coating provide durable performance across steel, aluminum, and stainless steel, while the straight shank and DIN 6539 compatibility simplify setup in a wide range of drilling systems. For professionals and hobbyists who demand reliable accuracy and consistent results, this drill delivers a dependable, long-lasting performance.
