Meet the Dormer Pramet A940 4.00 mm HSS-E High-Performance Multi-Application Straight Shank Long Series Drill DIN/ANSI. This compact 4 mm drill is built for precision, efficiency, and dependable performance across a range of metals, making it a go-to choice for everyday machining and demanding fabrication tasks.
Why this drill excels
- 130° point — starts cleanly and centers itself, reducing push force and minimizing wandering even in tougher workpieces.
- Bright finish — prevents workpiece material from sticking to the cutting edge, preserving edge life and delivering smoother cuts.
- Parabolic flute design — optimized for chip evacuation and allows drilling deeper holes in a single pass, boosting throughput and reducing cycle times.
- Premium HSS-E material — a robust high-speed steel alloy that handles steel, aluminium, and stainless steel with consistent performance and long tool life.
- Long series with straight shank — extended flute length provides reach for deeper holes while the DIN/ANSI straight shank ensures solid, repeatable engagement with standard chucks and collets.
- High-precision drilling — engineered to deliver high-quality, accurate holes even at higher speeds and feeds, achieving the specified h10 hole tolerance.
Ideal use cases
Perfect for toolmakers, fabricators, and engineering shops that need a reliable, all-purpose drill for metalworking. Use this drill for cleanly piercing steel, drilling through aluminum components, and creating precise holes in stainless steel without frequent tool changes. Its deep-hole capability makes it suitable for reach-intensive tasks in thin plates or structural members where precision and consistency matter most.
Practical tips for best results
- Pair with appropriate coolant/llooding to maximize edge life, especially when drilling stainless steel or tough alloys.
- Match the feed rate to the material and use a steady, perpendicular approach to maintain hole accuracy and minimize deflection.
- Keep the drill flute clean of chips during long hole drilling to prevent clogging and overheating.
- Use the drill in compatible machines (drill presses or CNCs) with standard collets/chucks designed for straight-shank tools.
