Description
Meet the Dormer Pramet R520 7.80 mm carbide stub drill. This DIN 6539 straight-shank drill is built for engineers, machinists, and tradespeople who need fast, accurate holes in steel, aluminium, and stainless steel. Its 130° point promotes self-centering and lowers the effort required to start a hole, while a TiN coating extends service life and sustains performance in tougher materials. Convex cutting edges help break chips for smooth removal and enable higher cutting speeds and feeds. The premium carbide core delivers reliable performance across a range of materials, making it a versatile choice for demanding drilling tasks.
- 130° self-centering point: Starts cleanly with reduced push force, improving hole alignment and reducing tool deflection during entry.
- TiN coating for extended life: Titanium Nitride coating boosts wear resistance, delivering longer tool life and steadier performance when drilling harder materials and abrasive workpieces.
- Convex cutting edges for chip control: Convex geometry aids chip breaking and evacuation, enabling higher cutting speeds and feeds for faster hole production without sacrificing quality.
This drill delivers reliable, high-quality holes with tight tolerances (H8) and versatility across steel, aluminium, and stainless steel. The 7.80 mm diameter, DIN 6539 straight shank design ensures compatibility with standard chucks for secure, vibration-free operation from start to finish. By reducing downtime through longer tool life and efficient cutting, it helps you streamline workflows, improve hole quality, and complete jobs with confidence in every cut.
