The Dormer Pramet A940 11/16 Inch HSS-E High-Performance Multi-Application Drill is built to elevate metalworking efficiency from first contact to final hole. This long-series, straight-shank drill combines precision geometry with durable materials to deliver clean, accurate results across a range of metals and millwork tasks. Designed to fit standard DIN/ANSI holders, it’s a reliable workhorse for fabrication shops, maintenance teams, and job sites where depth, accuracy, and throughput matter. What makes the A940 stand out - 130-degree point for self-centering starts: The sharp, purpose-built point minimizes wandering and reduces the pushing force required to begin cutting, helping you hit the mark on every hole. - Bright finish for smoother cutting: The polished edge reduces material sticking and built-up edge, promoting steadier cutting action and consistent hole quality. - Parabolic flute design for depth without pecking: This special flute geometry excels at chip evacuation and allows you to drill deeper holes in a single pass, improving cycle times and reducing heat buildup. - Premium HSS-E alloy: The cobalt-enhanced high-speed steel delivers improved hot hardness, enabling reliable drilling through steel, aluminium, and stainless steel with longer tool life. - High-performance, consistent results: Capable of maintaining precise hole quality at higher speeds and feeds, the A940 supports an h10 hole tolerance for tight, repeatable fits. - Long-series, straight shank for versatility: The straight shank provides secure grip in standard chucks and holders, while the extended length reaches into deeper pockets and through-holes without compromise. - DIN/ANSI compatibility: Engineered to work seamlessly with conventional industrial tooling standards, reducing setup time and ensuring dependable performance in familiar equipment. Ideal use cases - Fabrication and repair work requiring deep, accurate through-holes in steel, stainless steel, or aluminum. - Automotive and aerospace components where consistent hole quality at higher speeds matters. - General metalworking where a single drill can handle multiple materials and long reach is advantageous. Why this drill matters in your toolkit - You get a single, versatile tool designed to handle diverse materials with consistency, reducing the need to switch between specialized drills. - The combination of 130° point, bright finish, and parabolic flutes translates into smoother starts, cleaner holes, and faster overall cycle times. - With HSS-E construction and a long, straight shank, you gain reliability and compatibility across common drilling setups, improving uptime and reducing set-up friction. Practical tips for best results - Use appropriate cutting fluid or coolant to extend tool life, especially when drilling stainless steel or aluminum. - Start with a precision pilot or center punch to maximize the self-centering advantage of the 130° point. - Maintain steady feeds and avoid excessive load to keep chips evacuating through the parabolic flute and to preserve hole tolerance. - Secure the workpiece firmly and use proper clamping to minimize deflection during deeper drilling.
