Dormer Pramet R520 10.10 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 is a 10.10 mm diameter carbide stub drill with a straight DIN 6539 shank. Designed for reliable metalworking across a range of materials, it’s ideal for engineers, buyers, tradespeople, hobbyists, and anyone who needs consistently accurate holes with minimal effort.

This high-performance drill combines a 130° point for self-centering and reduced push force, a Titanium Nitride (TiN) coating to extend tool life and enhance performance on harder materials, and convex cutting edges that promote easier chip breaking and faster material removal. The result is a versatile tool capable of delivering smooth starts, improved cutting speeds, and steady hole quality.

• 130° point for self-centering and reduced push force: Promotes precise hole starts with less effort, improving first-pass accuracy and reducing user fatigue.
• TiN coating for longer service life: Hard-wearing surface lowers wear and extends drill life, particularly when drilling tougher metals.
• Convex cutting edges for efficient chip control: Chips break and evacuate more easily, enabling higher speeds and feeds without compromising hole quality.

With its premium carbide construction, this drill is suitable for drilling steel, aluminium, and stainless steel, delivering high-quality, accurate holes even at higher speeds and feeds. Its robust build and standard DIN 6539 straight shank ensure dependable compatibility with a wide range of holders and setups, helping you finish jobs faster with consistent results.
