Dormer Pramet R520 6.00 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 6.00 mm carbide drill is a straight-shank stub drill designed for precise, reliable holemaking across a range of materials. With a DIN 6539 shank and a 6.00 mm diameter, it fits standard drill chucks and holders for versatile use in workshops, manufacturing lines, and maintenance tasks. The 130-degree point helps self-center the starting hole and reduces the push force required, resulting in cleaner starts and less wandering.

Constructed from premium carbide and finished with a Titanium Nitride (TiN) coating, this drill is built to endure demanding drilling, including harder materials. Convex cutting edges promote efficient chip breaking and evacuation, enabling higher speeds and feeds while maintaining hole quality. It delivers consistent performance on steel, aluminum, and stainless steel and can achieve high-precision holes with tight tolerances (H8) when used with proper tooling and feeds.

• 130° self-centering point: Starts holes cleanly with less push force, improving accuracy and reducing wandering.
• TiN-coated premium carbide: Extends tool life and improves performance on steel, aluminium, and stainless steel, especially under higher speeds and loads.
• Convex cutting edges for efficient chip breaking: Aids chip evacuation and allows higher speeds and feeds for faster, smoother drilling and better surface finish.

Thanks to its DIN 6539 straight shank, this drill delivers secure grip and compatibility with a wide range of machines. The combination of premium carbide and TiN coating ensures durable, reliable performance at high speeds and feeds, producing accurate, consistent holes that meet H8 tolerance and reducing downtime across production runs. A dependable choice for engineering, fabrication, and maintenance work that demands repeatable results and long tool life.
