Dormer Pramet A940 3.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 3.00 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill is engineered for precision drilling across a range of materials, with a design that prioritizes accuracy, depth, and reliability in every hole. This is a DIN/ANSI standard drill built for demanding workshop environments where consistency matters as much as speed.

130° point for confident entry — The sharp 130-degree point self-centers as soon as it touches the workpiece, dramatically reducing the push force required and promoting clean, true starts. That means less wandering, quicker setups, and fewer rework cycles—especially on thin-wall sections or difficult-to-centre features.

Parabolic flute design for extra-deep holes — The special parabolic flute geometry is optimized for chip evacuation and straight-line progression, enabling you to drill deeper in a single pass without sacrificing hole quality. This makes it ideal for applications where hole depth exceeds the standard drilling reach, reducing the need for multiple pecking passes.

Bright finish to minimize sticking — A polished surface finish reduces built-up material on the cutting edge, helping to prevent workpiece material from sticking and galling. This results in smoother cuts, less stopping for cleanup, and longer tool life in aluminum, steel, and stainless materials.

Premium HSS-E material for versatility — The HSS-E composition delivers enhanced hot hardness and wear resistance, making the A940 suitable for drilling a variety of materials including steel, aluminum, and stainless steel. Whether you’re producing prototype parts or running a high-mpeed production batch, you’ll get consistently reliable performance.

Long, straight shank for extended reach — The straight shank design provides secure clamping in standard collets and chucks, while the long-series geometry offers increased reach without compromising rigidity. This makes it a practical choice for deep cavities, blind holes, and components with crowded geometries.

High-speed, high-accuracy drilling with h10 tolerance — Built for precision, the A940 maintains tight tolerances (h10) at elevated speeds and feeds. Expect crisp hole diameters, smooth surface finishes, and minimal rework when machining parts that demand tight control over dimensions and finish.

This drill is an excellent fit for machine shops, engineering workshops, automotive and aerospace components, and any operation that requires dependable multi-material drilling with depth and precision in mind. Its multi-application capability means you can deploy it across steel, aluminum, and stainless workpieces without swapping tools, saving time and reducing inventory complexity. With the A940, you’re choosing a long-series drill designed to deliver repeatable results, even when you push speeds and feeds higher to meet tight production schedules.
