Dormer Pramet A110 7.10 mm HSS ST Straight Shank Long Series Drill DIN 340 is a purpose-built drill bit designed for professionals who demand reliability, reach, and precision in metalworking. This long-series, straight-shank drill is optimized for deep-hole tasks while remaining compatible with standard chucks and drill presses, making it a versatile choice for shop floors and fabrication benches alike.

Key features that matter in real work

• 118° conventional point delivers a strong, self-centering bite that starts holes cleanly and reduces wandering. The geometry is also easy to re-grind, extending the life of the tool between sharpenings.
• Steam oxide finish minimizes material buildup on the cutting edge, promoting smoother chip flow and reducing the risk of gumming when drilling sticky metals or alloys.
• Long length series provides increased reach for deep holes and applications where access is limited. The extended flute length preserves rigidity so you can maintain hole accuracy even when drilling hundreds of millimeters into a workpiece.
• Premium HSS material (high-speed steel) offers solid wear resistance across a variety of materials, including steel, aluminium, and stainless steel. This makes the A110 drill a reliable general-purpose choice in mixed-material environments.
• Versatile for handheld and machine drilling with a straight shank design that fits securely in most collets and chucks, delivering consistent performance whether you’re using a drill press, magnetic drill, or a handheld unit.
• DIN 340 compliant construction ensures consistent dimensions and compatibility with standard tooling setups, simplifying replacement and ensuring predictable results across jobs.

Who benefits most

• Machinists and fabricators carrying out deep-hole tasks in steel, aluminium, or stainless steel components.
• Workshops that require a dependable drill for both handheld operations and machine-based drilling without swapping tools.
• Engineers and technicians who value a re-sharpenable point and a finish that promotes smooth cutting and reduced workpiece sticking.

Practical tips for best results

• Pair the A110 with appropriate speeds and feeds for the material being drilled; start with moderate engagement and increase gradually while monitoring chip formation.
• Use steady, light feeds to prevent overheating, which can dull the 118° point or cause workpiece galling, especially on stainless steel.
• Maintain clear chip evacuation on long holes—peck drilling in short intervals can help prevent clogging and extend tool life.
• Keep the cutting edge sharp; the re-grindable point makes it economical to refresh the tip rather than replacing the bit frequently.
• Lubricate or cool when drilling ferrous materials to prolong edge life and improve hole quality.

In environments where depth, consistency, and versatility matter, the Dormer Pramet A110 7.10 mm HSS ST Straight Shank Long Series Drill DIN 340 delivers dependable performance across a range of metals and applications. Add it to your toolkit for deeper holes, reliable starts, and a tool that stays sharp longer between re-grinds.
