Dormer Pramet R520 8.50 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 8.50 mm Carbide TiN CDX Straight Shank Stub Drill (DIN 6539) is a rugged, precision-ready drill built for everyday metalworking. Whether you’re in a workshop, fabrication shop, or home garage, this drill delivers reliable holes in a wide range of materials with a compact, straight-shank design that fits standard chucks.

With a 130-degree point for self-centering and reduced push force, a titanium-nitride coating that extends tool life, convex cutting edges that improve chip control, and premium carbide construction, it’s designed to perform at higher speeds and feeds while maintaining accuracy. It’s capable of drilling steel, aluminum, and stainless steel with consistent results and tight hole tolerances (H8).

• 130° Point for Self-Centering and Reduced Push Force: Helps start holes cleanly with less effort, improves accuracy, and reduces operator fatigue during repetitive drilling tasks.
• TiN Coating Extends Tool Life and Boosts Performance: The titanium nitride coating reduces wear and heat buildup, delivering longer service life and better performance when drilling harder materials.
• Convex Cutting Edges for Chip Control and Higher Speeds: Convex geometry breaks chips more effectively, keeps chips clear, and supports higher feed rates without sacrificing edge strength or hole quality.

The R520 8.50 mm carbide stub drill offers dependable, repeatable results across common metals, helping you finish projects faster with fewer tool changes. Its durable carbide construction, TiN coating, and optimized geometry deliver clean, true holes with tight tolerances, even at higher speeds and feeds. Trustworthy, versatile performance for professional manufacturing, maintenance, and hobbyist applications alike.
