Dormer Pramet A110 1.00 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 1.00 mm HSS ST Straight Shank Long Series Drill, a precision small-diameter bit designed for tight-fitting holes and extended reach. With a 1.00 mm diameter, this drill is engineered for clean starts and dependable performance in demanding metalworking tasks, whether you’re in a workshop or on the shop floor.

• 118° conventional point — delivers a strong starting bite that resists wandering and creates true, accurate hole entrances. The geometry also makes re-grinding straightforward, so you can extend the life of the tool between sharpenings.
• Steam oxide finish — a surface treatment that minimizes material adhesion to the cutting edge, helping chips clear smoothly and reducing built-up edge for steadier cutting action.
• Long length series — designed for drilling deeper holes and for applications where extra reach is required. The combination of long flute length and a rigid straight shank maintains stability in challenging setups.
• Premium HSS material — versatile enough to drill a range of metals, including steel, aluminium, and stainless steel, while delivering consistent performance and reliable edge life.
• Straight shank, DIN 340 — compatible with a wide array of chucks and holders in both handheld and machine-driven drilling, with standard dimensions that ensure dependable interchangeability.

Who benefits most from the A110 1.00 mm drill?

• Machinists and fabricators tackling precision, small-diameter holes in steel, aluminium, or stainless steel.
• Hobbyists or students who need a reliable, long-reach drill for metalworking projects, prototyping, or electronics enclosures.
• Prototypers and technicians performing handheld drilling or job-site machine work where depth and accuracy matter.

Use cases and practical insights

• Deep-hole tasks in components with limited access where a standard-length drill wouldn’t reach—perfect for chassis, housings, and thin-walled parts.
• Precision pilot drilling in small-diameter channels where burr-free entrances improve subsequent operations.
• Applications across multiple materials make this drill a versatile choice for mixed-material projects.

Optimization tips for best results

• Use appropriate cutting fluid or lubrication to minimize heat and extend edge life during small-diameter drilling.
• Start at a conservative spindle speed and steady feed rate, then adjust as the cut progresses to prevent deflection or chatter.
• Secure the workpiece firmly in a vise or drill press to maximize accuracy and reduce drift, especially when drilling deep holes.
• Inspect and re-grind the edge when you notice gradual dulling to maintain clean entry and hole quality.

Engineered for reliability, the Dormer Pramet A110 1.00 mm HSS ST Straight Shank Long Series Drill (DIN 340) delivers precise starts, deep-reaching capability, and broad material compatibility in a single, dependable small-diameter drill. Add it to your toolkit for meticulous metalwork that demands accuracy from first touch to final depth.
