Dormer Pramet R520 13.00 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

Meet the Dormer Pramet R520, a 13.00 mm carbide stub drill designed for professionals and hobbyists who demand precise, repeatable holes with high productivity. With a straight shank and DIN 6539 compatibility, it’s built to fit standard holders and deliver reliable performance across common workshop materials including steel, aluminium, and stainless steel.

The 130° point helps start holes with minimal wandering, reducing the push force required and improving initial hole accuracy. The Titanium Nitride (TiN) coating extends tool life and maintains sharpness when drilling harder materials, so you can drill longer between changes. Convex cutting edges promote easy chip breakage and evacuation, enabling higher speeds and feeds without sacrificing hole quality.

• 130° Point for Self-Centering and Lower Start‑Up Force: Improves hole accuracy from the first cut and reduces the effort needed to begin drilling, especially on harder or imperfect surfaces.
• TiN Coating for Extended Tool Life: Increases wear resistance and sustained performance when drilling tougher materials, reducing downtime for tool changes.
• Convex Cutting Edges for Efficient Cutting: Aids chip control and allows higher speeds and feeds, delivering consistent, high-quality holes with less rework.

Designed to deliver reliable results across a range of metals, this drill achieves high-quality, accurate holes with an h8 tolerance at productive speeds. Its premium carbide composition and optimized geometry ensure durability and consistent performance, making it a dependable choice for fabrication, maintenance, and everyday drilling tasks.
