Dormer Pramet R520 10.20 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 10.20 mm carbide stub drill is engineered for reliable holemaking across a range of metals. With a DIN 6539 straight shank and a 130° point, it starts holes accurately and reduces the push force required, helping you maintain speed and control whether you’re working with steel, aluminum, or stainless steel.

Designed for professionals, engineers, tradespeople, and serious hobbyists, it delivers consistent, high-quality holes even at high speeds and feeds, achieving tight H8 tolerance with minimal runout.

• 130° Point for precise starts: The 130° point design helps with self-centering and reduces push force, improving accuracy and reducing operator effort.
• TiN Coating for longer life: Titanium Nitride coating increases tool life and enhances performance when drilling harder materials, extending time between tool changes.
• Convex Cutting Edges for efficient chip control: Convex edges help break chips, aid removal, and allow higher cutting speeds and feeds for faster production.

In practice, this drill delivers consistent hole quality in steel, aluminum, and stainless steel, with tight H8 tolerance at higher speeds and feeds. The combination of premium carbide, a durable TiN coating, and optimized geometry minimizes wear, supports quick setup, and keeps production moving with dependable, repeatable results.
