Dormer Pramet A520 11.10 mm HSS TiN ADX STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A520 11.10 mm HSS TiN ADX Straight Shank Stub Drill is a versatile metalworking tool designed for professionals and hobbyists who demand precision and reliability. Built on a premium HSS core with a Titanium Nitride coating, it delivers longer tool life and dependable performance when drilling steel, aluminium, and stainless steel, achieving high-quality holes with h9 tolerance even at higher speeds and feeds.

The 130-degree thinned point centers itself to start holes cleanly, reducing push force and improving starting accuracy. Coupled with convex cutting edges, this drill promotes easy chip breakup and removal, enabling higher cutting speeds and feeds for productive drilling sessions.

• 130° thinned point: Self-centering starts reduce the push force required and help initial hole alignment for a cleaner, more accurate start.
• Titanium Nitride coating: Extends tool life and enhances performance when drilling harder materials, helping you achieve more holes between changes.
• Convex cutting edges: Improves chip control and allows higher speeds and feeds, delivering smoother cuts and faster material removal.

Designed for reliable, consistent results across a range of metals, this drill helps streamline workflows, reduce rework, and maintain tight tolerances. With its durable construction and precision geometry, you can trust it to deliver repeatable performance across projects.
