Dormer Pramet R520 9.70 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 is a 9.70 mm carbide stub drill designed for reliable, accurate hole fabrication across a wide range of metals. With a DIN 6539 straight shank, it fits most standard chucks and holders, making it a versatile addition to workshops, fabrication shops, and maintenance teams that demand dependable hole quality.

Its 130-degree point promotes self-centering and reduces the push force required, helping you start holes cleanly and with less effort. The Titanium Nitride coating extends tool life and enhances performance when drilling harder materials, keeping your work moving smoothly. Convex cutting edges improve chip control and enable higher cutting speeds and feeds, while the premium carbide construction delivers consistent, high-quality results in steel, aluminium, and stainless steel, with holes held to an h8 tolerance.

• 130° point for self-centering: reduces push force and start-up drift, delivering cleaner holes with less effort.
• TiN coating for longer life: increases wear resistance and maintains sharpness when drilling harder materials, reducing tool changes.
• Convex edges with premium carbide: promotes efficient chip breakage, supports higher speeds and feeds, and yields reliable, high-precision holes (h8 tolerance).

This drill is built for real-world use—delivering dependable performance across common engineering materials, ensuring consistent hole quality, and helping you keep production moving with fewer interruptions.
