Description
The Dormer Pramet R520 8.30 mm carbide TiN CDX straight shank stub drill (DIN 6539) is a high-performance drilling tool designed for precision metal work. Built for engineers, machinists, fabricators, and DIY enthusiasts, it delivers clean starts and consistent hole quality in steel, aluminium, and stainless steel.
Its 130° point self-centers to begin cutting with less push force and minimal wandering. The Titanium Nitride coating extends service life and maintains cutting performance when working with tougher materials. Convex cutting edges improve chip breaking and evacuation, enabling higher speeds and feeds without compromising hole accuracy.
- Self-centering 130° point: Starts holes with less push force and minimizes wandering for clean, accurate starts.
- TiN coating for longer tool life: Extends service life and sustains cutting performance when drilling harder materials.

The straight shank ensures compatibility with a wide range of chucks and holders, while DIN 6539 compliance guarantees reliable interchangeability with existing tooling. For engineers, builders, and hobbyists who value consistency, this Dormer Pramet R520 provides dependable performance and long-lasting reliability.
