Dormer Pramet A940 9/64 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 9/64 Inch HSS-E High-Performance Multi-Application Straight Shank Long Series Drill (DIN/ANSI) is built to deliver reliable hole quality across a range of metals. With a purpose-built balance of geometry, material, and finish, this drill is designed for everyday production as well as precision work in demanding environments.

• 130° point for self-centering and reduced push force: The sharpened tip starts holes cleanly, minimizes wandering, and makes entry smoother on busy machines where cycle time matters.
• Bright finish: The polished surface reduces built-up material on the cutting edge, which helps maintain a crisp cut and minimizes post-drilling cleanup.
• Parabolic flute design: Engineered to evacuate chips efficiently, it enables deeper holes in a single pass, reducing tool changes and improving throughput on longer workpieces.
• Premium HSS-E material: An enhanced high-speed steel with cobalt content delivers superior hot hardness and wear resistance, extending life when drilling steel, aluminium, and stainless steel.
• Long-series straight shank (DIN/ANSI): Precisely compatible with standard chucks and fixtures, offering stable performance in mills, lathes, and drill presses without needing adapters.
• High-performance drilling with tight tolerances: Capable of delivering high-quality, accurate holes at elevated speeds and feeds, targeting H10 hole tolerance for reliable interchangeability in assemblies.

This drill is ideally suited for machine shops, fabrication shops, and maintenance environments where one tool must handle multiple materials with consistent results. Use it for through-holes and deep-hole applications in steel, aluminium, and stainless steel, where dependable centering, chip evacuation, and surface finish directly impact cycle times and part quality.

Practical tips for top results: maintain proper peed and feed alignment to leverage the 130° point’s self-centering action, apply a suitable cutting fluid to manage heat with HSS-E, and choose conservative feeds at the start of a new material to establish the hole diameter before incremental increases. Remember to clamp the work securely to prevent deflection on longer holes, and periodically inspect the drill for wear to sustain precision across production runs.
