Dormer Pramet R520 15.10 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 15.10 mm carbide straight shank stub drill (DIN 6539) is a high-performance drilling solution designed for metalworking tasks across steel, aluminum, and stainless steel. It delivers precise, repeatable holes with minimal effort, making it suitable for engineers, machinists, and workshop use.

With a 130-degree point designed for self-centering, a Titanium Nitride coating that extends tool life, and convex cutting edges to promote smooth chip evacuation, this drill is built for reliable performance at higher speeds and feeds—helping you achieve an accurate h8 hole tolerance every time.

• 130° Point for Easy Start and Self-Centering: Reduces wandering at entry and lowers the push force required, helping you start holes cleanly and maintain accuracy.
• Titanium Nitride Coating for Longer Tool Life: Increases wear resistance and sustains steady performance when drilling harder materials, reducing downtime and sharpening frequency.
• Convex Cutting Edges for Efficient Chip Control: Promotes smoother chip breakage and removal, enabling higher cutting speeds and feeds for faster production without sacrificing quality.

This high-quality carbide drill combines durability with precise engineering to deliver reliable, high-quality holes quickly. The straight shank ensures compatibility with standard drill chucks, and the 15.10 mm diameter supports precise fits in demanding assemblies. Whether you’re working with steel, aluminum, or stainless steel, you’ll benefit from reduced downtime, consistent results, and a smoother drilling workflow.
