Dormer Pramet A940 9.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 9.00 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill DIN/ANSI is built for precision and versatility in modern metalworking. Designed to tackle a range of materials with one reliable tool, this drill combines advanced geometry with a tough HSS-E substrate to deliver clean, accurate holes—from steel to aluminum and stainless steel—even at higher speeds and feeds.

• 130° point for self-centering and reduced push force: The precise point geometry minimizes wandering at entry, helping you start holes confidently and maintain true alignment through the cut.
• Bright finish to minimize sticking: The polished cutting edge resists material buildup, which means fewer interruptions for cleanup and longer tool life between regrinds.
• Parabolic flute design for deep-hole drilling: Engineered to evacuate chips efficiently, this flute geometry enables extra-deep holes in a single pass without clogging or binding.
• Premium HSS-E material: A robust substrate optimized for drilling a variety of metals—steel, aluminum, and stainless steel—while offering improved wear resistance and long-term rigidity.
• Long series, straight shank (DIN/ANSI): The extended length and standard shank provide compatibility with a broad range of chucks and collets, delivering dependable rigidity in deep-hole work.
• High-performance with H10 hole tolerance: Delivers consistent hole sizes with tight tolerances, reducing finishing steps and enabling precise fits in assembly or subsequent machining.

Ideal use scenarios include fabricating multi-material assemblies, machining automotive components, and setting up repetitive production holes in steel plates, aluminum panels, or stainless workpieces. The A940’s architecture supports deep-through-hole tasks, long reach in confined spaces, and reliable performance at industrial speeds, making it a trusted choice for workshop professionals and shop floors alike.

What makes this drill stand apart

Unlike general-purpose drills, the A940 combines a 130° self-centering point with a parabolic flute that keeps heat and chips under control during deep cuts. The bright finish minimizes material adhesion at the cutting edge, while the HSS-E composition delivers durable performance across diverse metals. The DIN/ANSI long-shank design ensures compatibility with common drilling setups, so you can reach deep into tight cavities without compromising straightness or accuracy. For operators who depend on consistent hole quality and reduced deburring, this drill sets a new standard.

Practical tips for best results: choose speeds and feeds aligned with your material and machine capabilities, use proper lubrication or coolant to minimize tool wear, and monitor edge condition after extended use. When you need a single-tool solution for multiple metals and deep-hole projects, the Dormer Pramet A940 9.00 mm drill is ready to perform with precision and reliability.
