Description
The Dormer Pramet R520 14.25 mm carbide drill is a straight‑shank stub drill designed for precise, reliable holemaking across metalworking projects. With a DIN 6539 straight shank, it fits standard chucks and fixtures, making it a dependable choice for shops, engineers, tradespeople, and serious hobbyists alike.
Engineered for consistent results at higher speeds and feeds, this drill pairs a premium carbide core with geometry optimized for versatile performance on steel, aluminium, and stainless steel.
- 130° Self-Centering Point: Start holes cleanly with less push force, improving hole accuracy and reducing operator fatigue for faster, more consistent results.
- TiN Coating for Extended Life: Titanium Nitride coating increases tool life and maintains performance when drilling harder materials, reducing replacement costs and downtime.
- Convex Cutting Edges for Fast Cutting: Convex edges help break chips and allow higher cutting speeds and feeds with smoother chip evacuation for a better surface finish.
Designed to deliver high-quality holes with tight h8 tolerance, the R520 provides dependable performance across common metals. Its DIN 6539 straight shank ensures secure mounting in standard chucks, while the carbide construction and optimized geometry help you complete jobs efficiently, with fewer reworks and longer tool life.
