Dormer Pramet A940 8.70 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 8.70 mm HSS-E High Performance Multi-Application Drill with a straight shank and long-series reach. Built for pro workshops and production floors, this drill blends precision, durability, and versatility to simplify deep-hole tasks across multiple materials.

• 130-degree point for effortless self-centering and reduced thrust. Start holes cleanly with less effort, even in tougher materials.
• Bright finish minimizes galling and prevents workpiece material from sticking to the cutting edge, delivering smoother starts and cleaner holes.
• Parabolic flute design optimizes chip evacuation and enables deeper holes in a single pass, reducing tool changes and improving cycle times.
• Premium HSS-E material provides enhanced wear resistance and heat tolerance, making it suitable for drilling steel, aluminum, and stainless steel with consistent results.
• Long-series, straight-shank design delivers extended reach without compromising rigidity, while DIN/ANSI compatibility ensures reliable fit in a wide range of holders and machines.
• High-performance precision capable of delivering high-quality, accurate holes even at elevated speeds and feeds, achieving tight tolerances (H10) when paired with proper tooling setup.

This drill is ideal for applications where depth and accuracy matter—think automotive components, fabrications with thick sections, and aerospace-grade workpieces where reliable hole quality at depth is essential. The A940 excels in multi-material environments, enabling you to tackle steel frames, aluminum blocks, and stainless assemblies with a single, capable tool.

Practical tips for best results: match spindle speed and feed rate to the material being drilled, use appropriate coolant to manage heat, and clamp securely to minimize tool deflection during deep-hole operations. The parabolic flute and long-series profile help you reach recessed features or through-holes without sacrificing finish or dimensional accuracy, making this drill a dependable workhorse in metalworking shops.
