Dormer Pramet A940 1.00 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 1.00 mm HSS-E High-Performance Multi-Application Long Series Drill. Designed for precision work across a range of materials, this DIN/ANSI straight-shank drill delivers consistent, dependable results in demanding applications.

Why the A940 stands apart

• 130° point geometry engineered for immediate self-centering and reduced push force, helping you start holes with confidence and minimizing wandering in tough metals.
• Bright, non-stick finish minimizes built-up edge by reducing material adhesion to the cutting edge, ensuring cleaner starts and smoother drilling cycles.
• Parabolic flute design enables deeper holes in a single pass, expanding your capability to reach long depths without multiple partial steps.
• Premium HSS-E substrate provides robust wear resistance and toughness, suitable for drilling a variety of materials including steel, aluminum, and stainless steel.
• High-performance drilling supports high speeds and feeds while maintaining h10 hole tolerance for precise, repeatable hole sizes in production runs.

What you can do with the A940

Ideal for sketch-to-production workflows where hole quality and depth matter. Use it for:

• Micro-drilling and precision holes in thin-to-medium gauge steel and stainless steel components.
• Aluminum fabrication where fast chip evacuation and clean edges are critical.
• Prototype development and small-batch production requiring tight tolerances and reliable repeatability.

Performance that translates to real-world results

The A940’s combination of a 1.00 mm diameter, long series length, and straight shank provides a stable, accurate drilling experience even in challenging setups. Its 130° point reduces first-pass deflection, while the parabolic flute accelerates chip removal, helping maintain surface finish and dimensional accuracy at higher speeds. This makes the A940 a strong choice when you need repeatable hole quality with fewer tool changes and less downtime.

Compared to standard drills, this design minimizes your processing steps and improves throughput—particularly valuable in precision engineering, electronics housings, and light structural work where every micron counts.

Accessibility and reliability are built in. The A940 is compatible with common DIN/ANSI holders and can be integrated into existing drilling cells or manual setups without special adapters. With its durable HSS-E construction, you’ll benefit from longer tool life and consistent performance across multiple material types.

To maximize results, pair the A940 with appropriate fixation and rigid tooling, maintain proper speeds and feeds for the material you’re drilling, and use a light lubrication strategy to extend edge life and reduce heat buildup during deep-hole operations.
