Dormer Pramet A940 3.60 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 3.60 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI is engineered for dependable precision across a variety of metals. This compact yet capable drill blends a robust HSS-E core with a design that emphasizes accuracy and efficiency in every hole.

Why this drill stands out

• 130-degree point facilitates fast self-centering and reduces push force, helping you start holes cleanly with less wandering.
• Bright finish minimizes material build-up on the cutting edge, promoting smoother cuts and longer edge life.
• Parabolic flute design enhances chip evacuation and stability, enabling extra-deep holes in a single pass without compromising accuracy.
• Premium HSS-E material delivers reliable performance across steel, aluminium, and stainless steel, with solid wear resistance for repeated use.
• High-performance drill capable of maintaining hole quality at higher speeds and feeds, achieving h10 hole tolerance for precise fits.
• DIN/ANSI straight shank, long-series provides rigid guidance and compatibility with standard chucks, ideal for reach-demanding applications.

Ideal use cases

Choose the A940 3.60 mm for consistent, high-quality holes in automotive assemblies, metal fabrication, and machinery housings. Its long-series straight shank is particularly advantageous when drilling deep pockets or reaching recessed areas where shorter tools struggle to maintain stability. The drill’s versatility makes it a reliable workhorse for multi-material projects, minimizing tool swaps without sacrificing hole integrity.

Practical advantages over standard drills

Compared with traditional high-speed steel options, the HSS-E core offers better toughness and heat resistance, allowing higher cutting speeds and extended tool life. The parabolic flute geometry reduces chatter and improves chip control, helping you achieve smoother finishes and fewer reworks. This drill is designed for multi-material workflows, so you can rely on one tool to handle steel, aluminum, and stainless steel tasks with consistent results.

Tips for getting the best results

• Start with conservative feeds to establish stable cutting, then optimize for finish quality and production speed.
• Secure workpieces firmly to prevent deflection on the long-series shaft during deep holes.
• Use a precise center punch to leverage the 130-degree point’s self-centering capability for a clean hole start.
