Dormer Pramet A110 1/4 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 1/4 Inch HSS Straight Shank Long Series Drill (DIN 340) is a precision tool built for deep-hole drilling with dependable performance in metalworking, fabrication, and workshop settings. Designed to tackle demanding applications, this drill combines a robust point geometry with a finish that keeps chatter and material sticking to a minimum.

• 118-degree conventional point for confident starts, reduced wandering, and a strong cutting edge that stays sharp longer. It’s also easy to re-grind when you need to refresh the edge between jobs.
• Steam oxide finish helps minimize workpiece adhesion on the cutting edge, promoting smoother feeds, cleaner holes, and improved chip evacuation in tough metals.
• Long length series enables deeper hole drilling and increased reach without compromising rigidity. Ideal for manufacturing fixtures, through-holes, and recessed pockets where access is limited.
• Premium HSS material delivers reliable performance across a range of materials, including steel, aluminium, and stainless steel. This makes the A110 a versatile choice for mixed-material projects.
• DIN 340 straight shank design ensures compatibility with a wide range of hand-held and machine-driven setups, providing stable chuck engagement and consistent drilling accuracy.

Who is this drill ideal for? Professionals and hobbyists who need a dependable, long-reach drill that can handle deep holes without wandering. It’s a smart choice for metal fabricators, automotive enthusiasts, and workshop technicians who frequently switch between materials and drilling depths.

Why choose the Dormer Pramet A110 1/4 Inch HSS Straight Shank Long Series Drill? It blends a purposeful geometry with a durable HSS core and an oxide finish to minimize sticking and maximize edge life. Compared to shorter, generic drills, this long-series design reduces the need for multiple tools when you’re working on deep or hard-to-reach holes, helping you complete projects faster with fewer tool changes.

Practical tips for best results: use a steady feed rate and moderate cutting speed appropriate to the material, apply a light cutting fluid to stainless steel or aluminum when the hole depth increases, and regularly inspect the edge—if you notice any dulling, re-sharpen the 118° point to maintain clean starts and accurate hole diameters.
