Meet the Dormer Pramet A940 14.50 mm HSS-E High Perf Multi-App Straight Shank Long Series Drill DIN/ANSI—a purpose-built solution for demanding metalworking tasks. This drill is engineered to deliver consistent, high-quality holes across a range of materials, from steel to aluminum and stainless steel, without the usual trade-offs between speed, accuracy, and tool life.

Key design advantages that matter in real-world work

• 130° point for self-centering and easier penetration: The precision ground point reduces wandering and lowers the push force required, helping you start holes cleanly every time and minimize chatter.
• Bright finish to prevent sticking: The polished cutting edge minimizes built-up material adhesion, promoting smoother drilling and longer edge life—even on challenging workpieces.
• Special parabolic flute design: Engineered to evacuate chips efficiently, this flute geometry enables deeper holes to be drilled in a single pass, reducing cycle times and improving hole straightness.
• Premium HSS-E material: A superior steel of enhanced toughness and heat resistance, optimized for drilling a variety of metals—from straightforward steel to nonferrous alloys—without sacrificing surface finish or tolerance.
• DIN/ANSI straight shank, long-series: Built for dependable alignment and balanced performance in standard drill chucks, collets, and CNC setups, with a longer reach for through-holes and deeper drilling tasks.
• High-performance hole quality (H10 tolerance): Consistently deliver accurate hole diameters at higher feed rates and speeds, reducing secondary operations and part rework.

Designed for precision-focused shops, the A940 drill excels in manufacturing, automotive, and general fabrication environments where you need to punch clean, precise holes quickly and reliably. Its versatile multi-application capability means one drill can handle a spectrum of materials and thicknesses—streamlining tooling inventories and improving production efficiency.

Use cases you’ll appreciate:

• Deep-hole drilling in aluminum fixtures or steel frames where a single-pass approach saves time.
• Piercing through stainless steel assemblies with minimal edge chipping and good surface finish.
• High-speed drilling in factory automation setups where repeatable hole quality reduces inspection overhead.

Practical tips for optimal results:

• Match spindle speed and feed rate to the material and hole depth, and use ample lubrication or coolant to dissipate heat and extend tool life.
• Keep the drill sharp and clean; a dull edge increases push force and decreases hole quality.
• Start with a light pilot hole if the workpiece is particularly hard or brittle to ensure consistent self-centering.
• Securely clamp the workpiece to prevent vibration, especially when drilling long series or deep holes.

For operators who demand reliability, consistency, and efficiency in metal fabrication, the Dormer Pramet A940 drill is a smart, single-solution choice that supports high-speed, high-accuracy drilling without frequent tool changes.
