Meet the Dormer Pramet A110 17.0 mm HSS ST Straight Shank Long Series Drill (DIN 340) — a purpose-built tool designed to tackle deep-hole work with precision and reliability. Engineered for metalworking, this drill combines a robust 118° conventional point with a long flute length to deliver consistent hole quality across a range of materials.

• 118-degree conventional point: provides a strong, self-centering start that minimizes wandering and remains easy to re-sharpen when needed.
• Steam oxide finish: reduces friction and prevents workpiece material from sticking to the cutting edge, promoting smoother swarf evacuation and cleaner starts.
• Long length series: engineered for deep holes and situations where extra reach is essential, enabling extended drilling without multiple tools.
• Premium HSS material: a durable high-speed steel solution capable of drilling through steel, aluminium, and stainless steel with reliable edge life.
• Versatile for handheld and machine applications: designed to perform equally well in drill presses, CNC machines, and handheld drills, offering flexibility in workshops and on-site work.
• DIN 340 compliant: built to DIN 340 standards, ensuring compatibility with common tool holders and dependable performance in standard metalworking setups.

Practical tips for best results: use appropriate cutting fluid for metallic work, maintain steady feed pressure to preserve hole diameter, and secure the workpiece to prevent deflection. Regularly inspect the drill tip for wear to maintain clean starts and consistent hole dimensions, especially when drilling thicker sections.

Designed for shop technicians, fabricators, maintenance professionals, and ambitious hobbyists who need a long-reach drill that doesn’t compromise on durability or accuracy. From mounting holes in steel brackets to deep through-holes in aluminum panels, the A110 long-series drill delivers reliable performance across a spectrum of metalworking tasks.
