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

Meet the Dormer Pramet A110 1 Inch HSS ST Straight Shank Long Series Drill, DIN 340—engineered for professionals who demand depth, precision, and reliable metal removal in demanding work settings. This isn't a one-trick bit; it's a durable solution designed to tackle thick materials and extended drilling tasks with consistent performance.

• 118-degree conventional point delivers immediate bite and strong start, making entry clean and predictable. The geometry is also easy to re-grind, helping you extend tool life between sharpenings.
• Steam oxide finish reduces build-up at the cutting edge, improving chip control and minimizing workpiece sticking during prolonged cuts—especially useful when working with steel and other alloys.
• Long length series provides increased reach for deeper holes, helping you access recessed areas, through-holes in frame members, and components with limited access without compromising rigidity.
• Premium HSS material offers strong wear resistance across a range of materials, including steel, aluminium, and stainless steel, ensuring dependable performance in everyday fabrication and production tasks.
• 1 inch diameter with straight shank (DIN 340) ensures compatibility with standard drill chucks and collets, delivering stable, straight cutting notes and minimizing runout in handheld or machine drilling setups.
• Versatility for handheld and machine applications—whether you’re outfitting a CNC, drill press, or a portable drill, this long-series drill bit maintains balance and cutting efficiency across applications.

Designed for professionals who drill deeper and work harder, the A110 long-series drill bit reduces tool changes and delivers predictable results across a range of materials. Its robust construction makes it an ideal choice for fabrication shops, maintenance teams, and DIY enthusiasts tackling ambitious projects that demand accurate, clean holes every time.

Practical tips for optimal performance: start with a centered mark or pilot hole to guide the bit, use cutting fluid or light lubrication when drilling steel, maintain a steady feed rate to prevent wandering, and periodically re-sharpen the point to preserve edge geometry. With proper use and regular maintenance, the Dormer Pramet A110 drill becomes a dependable workhorse in your toolkit, ready to handle deeper holes and challenging applications with confidence.
