Dormer Pramet A940 6.20 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 6.20 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill. Built for modern metalworking, this drill delivers consistent hole quality across materials and applications, making it a dependable choice for demanding workshops and production floors. The combination of precise geometry, robust carbide-like wear resistance, and a long reach means fewer tool changes and more productive cycles.

Why this drill stands out

• 130° point for self-centering and reduced push force: The pointed tip helps the drill start exactly where you intend, minimizing drift and making starter holes reliable even in tougher metals. This feature is designed to improve hole location from the very first contact.
• Bright finish to prevent sticking: The polished edge reduces friction and guards against built-up edge, helping maintain a clean cutting edge and smoother chip flow.
• Parabolic flute design for deep holes: The flute geometry provides extra space for chips to exit, enabling deeper drilling in a single pass and reducing the need for multiple pecking cycles. This is especially beneficial when working with longer hole depths.
• Premium HSS-E material: An advanced cobalt-based high-speed steel formulation delivers durability and consistent performance across a range of metals, including steel, stainless steel, and other alloys encountered in everyday fabrication.
• Long, straight shank for versatility: The straight shank and extended reach are designed to fit standard chucks and holders, enabling deeper access in bulky workpieces without compromising rigidity.
• DIN/ANSI standard compatibility: Engineered to integrate seamlessly with machines and fixtures used across global shops, ensuring reliable performance in mixed-tool environments.

What this means in practice

• High-speed, high-accuracy drilling: The A940 line is designed to produce precise holes at elevated speeds and feeds, targeting tight hole tolerances such as H10 in a variety of materials. This makes it suitable for production runs where consistent hole size and finish matter.
• Multi-material capability: While optimized for tough steels, stainless steels, and similar alloys, the A940 drill is built to perform reliably in mixed-material environments common in fabrication and machine shops.
• Deep-hole efficiency: With its parabolic web and long flute length, you can achieve deeper holes in a single pass, reducing cycle time and improving process reliability.
