Meet the Dormer Pramet A940 9.50 mm HSS-E High Performance Multi-App Straight Shank Long Series Drill (DIN/ANSI). Built for serious metalwork, this drill bit is purpose‑built to deliver consistent, high‑quality holes across a range of materials and applications. Its combination of precise geometry, premium material, and enduring finish makes it a reliable workhorse in any workshop or production line.

• 130-degree point for effortless starts — The sharp, self‑centering point reduces walk and lowers the push force required to begin cutting. In practice, you get cleaner starts on challenging materials and less wandering at the entry, which translates to tighter tolerances and fewer re-drills.
• Bright finish for smoother cutting and easier cleaning — The bright finish minimizes built‑up edge and prevents workpiece material from sticking to the cutting edge. That means fewer pull‑backs, smoother chip flow, and less time spent deburring or cleaning the hole after drilling.
• Parabolic flute design for deep-hole efficiency — The parabolic flute geometry enhances chip evacuation and stability, enabling you to reach deeper holes in a single pass. This reduces cycle times, lowers heat buildup, and minimizes the risk of clogging when drilling long depths or through‑holes in thick sections.
• Premium HSS-E material for versatile performance — This drill uses high‑speed steel with enhanced properties to tackle a broad material range, including steel, stainless steel, and aluminum. The HSS‑E construction provides improved wear resistance and toughness compared with standard HSS, delivering longer tool life and dependable performance under demanding speeds and feeds.
• Long, straight shank for compatibility and reach — The straight shank is designed for broad machine‑tool compatibility (DIN/ANSI standards) and ensures a secure grip in chucks and collets. The long series geometry also gives you extended reach for cavities, pockets, and deep recesses without changing tools.
• High-precision, high-speed drilling — Engineered to maintain hole geometry at higher speeds and feeds, this drill consistently delivers accurate holes with an H10 tolerance. It’s ideal when dimensional accuracy and surface finish are critical, such as precision housings, jigs, and assemblies.

Who benefits most from the Dormer Pramet A940? engineers, machinists, and fabricators who need a single, reliable drill that covers multiple applications without swapping tools. It shines when drilling through steel and stainless steel for structural components, automotive parts, and machinery housings, as well as locating or pilot drilling into aluminum projects where chatter and wandering can compromise accuracy. If you’re crafting long pockets, deep bores, or through‑holes in thicker panels, this drill’s flute design and long reach help you complete the job in fewer passes with cleaner results.

Performance you can feel in every hole:

• Consistent hole quality— The combination of a precise tip, robust flute geometry, and reliable HSS‑E material yields clean holes with smooth edges, reducing the need for secondary finishing steps.
• Reduced downtime— Deep drilling in a single pass with efficient chip evacuation minimizes tool changes and interruptions, keeping production moving and improving overall throughput.
• Lower risk of dulling— Premium HSS‑E stands up to tougher materials, giving you longer tool life in busy shops where drills encounter a variety of metals and thicknesses.
• Versatility without compromise— Designed for multi‑use drilling tasks, this drill handles a wide material range, so you can rely on one tool for many projects instead of stocking multiple bits for different metals.

Practical tips to maximize results with the A940:

• Match speeds and feeds to the material: moderate to high speeds for aluminum, and controlled feeds for steels and stainless to maintain a cool cutting zone and preserve edge life.
• Use light to moderate coolant or drilling fluid to control heat buildup and flush chips away from the flute channels.
• Start with a light touch using the 130° point to establish a true center, then bring up the feed rate gradually to maintain calm cutting and avoid deflection.
• Keep the drill sharp and clean; a dull edge increases torque and reduces hole quality, especially in deeper bores.
• Inspect hole tolerance regularly; with H10 tolerance, verify that the bore diameter remains within the required tolerance window for your assembly.

Designed for reliability in job shops and production environments where uptime matters, the Dormer Pramet A940 drill brings multi‑material capability, deep‑hole efficiency, and consistent precision into a single, DIN/ANSI compliant tool. If you’re upgrading your drilling toolkit, this long series straight shank drill is crafted to handle demanding tasks with less fuss and more predictable results.
