Dormer Pramet A110 2.70 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 2.70 mm HSS ST Straight Shank Long Series Drill (DIN 340) is built for precision drilling where depth and accuracy matter. Designed for professional use in metalworking, this drill combines a robust tip, resilient material, and a long flute length to tackle deeper holes with confidence.

• 118° conventional point — precise, self-centering entry that starts clean holes and remains easy to re-sharpen for repeated use.
• Steam oxide finish — reduces built-up edge by minimizing material adhesion at the cutting edge, promoting smoother cuts and less clogging.
• Long length series — extended reach for deeper holes and applications where access is limited, making it ideal for pockets, channels, and through-holes.
• Premium HSS material — versatile performance across common metals, including steel, aluminum, and stainless steel, with reliable wear resistance.
• Straight shank (ST) — universal compatibility with most handheld drills and machine tools, delivering secure grip and true alignment.
• DIN 340 compliance — ensures interchangeability with standard tool holders and consistent sizing across setups.

Ideal for machinists, fabricators, maintenance technicians, and serious DIYers who need precision holes in metal with extended reach, the A110 drill excels in both handheld drilling and machine-driven operations. Use it for pilot holes, deeper bungs, or finishing passes where accuracy and clean starting holes matter most.

Why choose this drill over others? The combination of a sharp, re-sharpenable 118° point, steam oxide edge protection, and a long flute geometry translates to predictable hole quality, reduced suction and vibration, and extended tool life in demanding materials. Pair it with the right chuck and steady feed to maximize performance in steel, aluminum, and stainless steel projects alike.

Tip for best results: maintain a consistent feed pressure, use proper lubrication or cutting fluid where appropriate, and select a drill speed suitable for the material being drilled to preserve edge geometry and achieve clean, accurate holes.
