Dormer Pramet R520 13.50 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 13.50 mm carbide stub drill is built for precise, repeatable hole‑making across common metals. With a DIN 6539 straight shank, it fits standard chucks and holders for efficient use in workshops, maintenance bays, and production environments.

A 130° point provides self‑centering action to start holes cleanly, while a Titanium Nitride (TiN) coating reduces wear and extends tool life. Convex cutting edges reduce chip buildup, enabling higher cutting speeds and feeds with consistent hole quality.

• 130° Point for Self-Centering: The 130-degree point starts cuts cleanly and minimizes wandering, reducing push force and delivering true, accurate starts every time.
• TiN-Coated Premium Carbide: Titanium Nitride coating paired with premium carbide extends tool life and maintains sharpness when drilling steel, aluminium, and stainless steel for longer, more reliable performance.
• Convex Cutting Edges for Chip Control: Convex edge geometry promotes easy chip breakage and removal, enabling higher speeds and feeds with smooth, consistent hole quality.

Designed for dependable performance across steel, aluminium, and stainless steel, this drill delivers high‑quality holes with tight H8 tolerances and reduced downtime. The combination of a precise starting point, wear‑resistant coating, and chip‑friendly geometry makes it a reliable choice for engineers, machinists, and tradespeople who value accuracy, speed, and durability in everyday drilling tasks.
