Meet the Dormer Pramet A940 11.00 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill, designed to tackle a wide range of materials with consistent precision. This DIN/ANSI-standard drill brings together durability, accuracy, and versatility in a single, reliable tool for professional workshops and production environments.

Key features that matter in daily drilling

• 130° point — delivers fast, self-centering starts and reduces push force, helping you maintain control and minimize wandering when starting holes in tough or reactive materials.
• Bright finish — a satin-bright surface that helps prevent workpiece material from sticking to the cutting edge, reducing built-up edge and improving chip flow.
• Parabolic flute design — engineered to evacuate chips efficiently, enabling deep-hole drilling in a single pass and reducing re-drilling or exit burrs.
• Premium HSS-E material — high-speed steel with enhanced toughness and wear resistance, suitable for drilling a broad spectrum of metals, including steel, aluminium, and stainless steel.
• Long series with straight shank — optimized for stability in longer drill operations, compatible with standard drill chucks and tools while preserving rigidity at higher speeds and feeds.
• High performance and precision — designed to deliver clean, accurate holes with H10 tolerance, making it a dependable choice for precision work and production runs.

This multi-application drill excels in environments where you need one tool that can handle diverse materials without swapping bits. Whether you’re fabricating steel components, machining aluminium enclosures, or finishing stainless parts, the A940 maintains hole quality, reduces tool wear, and speeds up setup times.

Who benefits most

• Machinists and toolmakers who require a reliable, single-drill solution for mixed-material work.
• Manufacturing shops looking to optimize tool inventories with a versatile, long-series drill capable of deep-hole drilling in a single pass.
• Maintenance workshops that value consistent hole quality at high speeds and feeds, with reduced chip buildup.

Practical tips for best results

• Match the drill to a rigid setup and a well-balanced spindle to maximize the A940’s deep-hole performance.
• Use appropriate coolant or cutting fluid to sustain edge life and control heat, especially at higher speeds.
• Start with a light feed to leverage the 130° point’s self-centering action, then increase the feed as the hole engages fully.
• For deep holes, ensure steady pecking or continuous threading is avoided to prevent chip clogging; rely on the parabolic flute to maintain smooth chip evacuation.

In short, the Dormer Pramet A940 11.00 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill is a robust, one-tool solution for professional metalworking. It’s built to deliver precise, repeatable results across multiple materials and applications, saving time, reducing tool changes, and helping you achieve consistent hole quality from the first pass to the last.
