Dormer Pramet A520 7.10 mm HSS TiN ADX STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A520 7.10 mm HSS TiN ADX Straight Shank Stub Drill (DIN 1897) is a versatile metalworking drill designed for professionals and hobbyists who need dependable, precise holes across steel, aluminium, and stainless steel. With a straight shank and compact stub length, it’s ideal for tight spaces and general drilling tasks where consistent results matter.

Its 130-degree thinned point enables self-centering with minimal start-up push, helping you begin holes cleanly and with less effort. The Titanium Nitride coating extends tool life and improves performance on harder materials, while convex cutting edges promote easier chip breaking and allow higher speeds and feeds for faster production without sacrificing accuracy (H9 hole tolerance).

• Thinned 130° point for self-centering: Reduces push force at start-up and helps you begin holes accurately with less drift.
• TiN coating for longer tool life: Enhances wear resistance and consistent performance when drilling harder metals, improving overall uptime.
• Convex cutting edges for efficient chip control: Aids chip breakup and enables higher cutting speeds and feeds for faster, reliable hole production.

This drill delivers reliable, accurate holes quickly across a range of metals thanks to the optimized point geometry, coating, and edge design. The combination of a robust HSS core and TiN coating reduces rework and tool changes, supporting smoother workflows, shorter cycle times, and better overall hole quality with tight H9 tolerances for dependable assemblies.
