Dormer Pramet A520 12.50 mm HSS TiN ADX STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A520 12.50 mm HSS TiN straight shank stub drill (DIN 1897) is a versatile drilling tool built for reliable, precise hole-making across a range of metals. With a straight shank and standard DIN 1897 designation, it fits standard drill chucks and setups used by professionals and hobbyists alike.

Its 130° thinned point promotes self-centering and reduces the push force at the start of cutting, helping you achieve cleaner starts with less effort. A Titanium Nitride coating extends the drill’s service life and boosts performance when drilling harder materials. Convex cutting edges aid chip breaking and removal, enabling higher cutting speeds and feeds for consistent, productive hole production. The tool is made from premium HSS, suitable for drilling steel, aluminium, stainless steel, and other common materials, delivering high-quality holes with h9 tolerance.

• 130° Thinned Point: Self-centering start with reduced push force for smoother, cleaner holes.
• Titanium Nitride Coating: Extends drill life and improves performance when drilling harder materials.
• Convex Cutting Edges: Aids chip breaking and removal, enabling higher speeds and feeds for faster hole production.

Designed for high performance in production and precision work, this drill helps you achieve consistent, accurate holes quickly. The combination of self-centering geometry, wear-resistant TiN coating, and robust edge design supports reliable results across steel, aluminium, and stainless steel, reducing downtime and the need for rework while delivering tight tolerances (h9) at elevated speeds and feeds.
