Dormer Pramet R520 11.50 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

Introducing the Dormer Pramet R520 11.50 mm carbide TiN CDX straight shank stub drill (DIN 6539). This versatile drill is designed for professionals and serious hobbyists who need reliable, accurate holes across a range of materials including steel, aluminium, and stainless steel. With a straight shank and DIN 6539 compatibility, it fits a wide variety of chucks and holders for quick, dependable setup.

Designed for precision and durability, it features a 130-degree point for self-centering and reduced push force, a Titanium Nitride coating to extend tool life and performance on harder materials, and convex cutting edges that break chips more easily to aid removal. These features enable high-speed drilling with consistent hole quality, even at demanding speeds and feeds (h8 hole tolerance).

• 130° Point for Self-Centering: Starts holes with minimal wandering and lowers the effort required to begin cutting, improving first-pass accuracy across metals and alloys.
• TiN Coating for Longer Tool Life: The Titanium Nitride layer reduces wear and maintains sharpness, delivering durable performance in tough materials and high-speed applications.
• Convex Cutting Edges for Efficient Chip Handling: Promotes easier chip breakage and faster removal, enabling higher speeds and feeds while maintaining hole quality.

With the R520, you gain faster, more predictable drilling cycles, reduced downtime from chip clogging, and consistently accurate holes that meet stringent tolerances. Its robust carbide core and coating work together to deliver reliable performance across common machining tasks, making it a dependable choice for workshop efficiency and quality results.
