Dormer Pramet A110 2.25 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 2.25 mm HSS Straight Shank Long Series Drill DIN 340 is purpose-built for precision metalworking where tiny diameters demand serious reach. This long-series drill combines a robust 118° point with a steam-oxide finish and a straight shank, delivering reliable starts, cleaner holes, and extended reach for deep-hole work in steel, aluminium, and stainless steel.

Designed to bite quickly and hold its edge, the 118° conventional point is easy to re-grind, helping you extend tool life without sacrificing accuracy. The point geometry minimizes wandering on initial entry and creates a precise entry kerf, even in challenging materials.

• Steam-oxide finish: reduces workpiece material from sticking to the cutting edge, yielding cleaner holes and steadier feeds in ferrous and non-ferrous metals.
• Long-length design: overall length around 90 mm with a flute length near 59 mm, giving you extended reach for deeper holes without compromising rigidity in small-diameter work. This long-series geometry is purpose-built for applications where depth matters.
• Premium HSS material: high-speed steel construction provides dependable cutting performance across a range of materials, including steel, aluminium, and stainless steel, with good wear resistance for everyday metalworking tasks.
• DIN 340 / straight shank: manufactured to the DIN 340 standard with a straight shank that fits a wide array of chucks and holders, making it compatible with both handheld and machine drilling setups.
• 6× D drilling depth capability: designed for drilling without pecking up to typical depths dictated by the 6×D guideline, helping you maintain steady feeds and consistent hole quality on longer projects.

This drill is ideal for technicians, small machine shops, and hobbyists who need a tiny-diameter tool that can reach into recessed features, boss pockets, or confined fixtures while still delivering dependable hole quality in a variety of metals. Whether you’re fabricating thin-walled components, setting pilot holes for assemblies, or creating precise micro-holes in prototypes, the A110 long-series drill keeps your workflow efficient and predictable. Its straightforward re-sharpen capability and compatible shank design reduce downtime and help you maintain tight tolerances across multiple projects.
