Dormer Pramet A110 1.50 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 1.50 mm HSS straight shank long series drill, DIN 340 — a precision micro-drill built for accurate, reliable holes in a range of metals. This small-diameter bit combines a robust point geometry with durability you can count on in both handheld and machine drilling environments.

The 118-degree conventional point delivers clean starts with minimal wandering, making it easy to align and re-sharpen for extended tool life. Paired with a steam oxide finish, it reduces workpiece material from sticking to the cutting edge, promotes smoother chip flow, and helps you achieve consistent hole quality even under higher cutting speeds.

• steady starts, precise hole placement, and quick edge refresh when needed.
• Steam oxide finish: lowers friction, minimizes built-up edge, and supports cleaner entry cuts.
• Long length series: exceptional reach for deeper holes and through thicker sections without compromising rigidity.
• Premium HSS material: versatile performance across steel, aluminium, and stainless steel with reliable wear resistance.
• Straight shank DIN 340: broad compatibility with common chucks and fixtures, ensuring stable alignment in both hand-held and machine setups.
• 1.50 mm diameter: ideal for precision pilot holes, delicate fastener clearances, and intricate metalwork where tight tolerances matter.

Designed for a wide range of metalworking tasks, this drill is a go-to choice for machinists, fabricators, and serious hobbyists tackling small, high-precision holes. Whether you’re drilling into steel, aluminium, or stainless steel, the A110’s combination of a strong point, anti-adhesion finish, and extended reach delivers dependable performance where precision counts.

Use cases include: creating pilot holes for delicate fasteners in sheet metal assemblies, drilling through thicker components from accessible faces, and completing tasks where tool longevity and repeatable hole quality are essential. For best results, secure the workpiece, apply light to moderate feed pressure, and use appropriate cutting fluid to manage heat and chip evacuation.
