Dormer Pramet A940 3/32 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Introducing the Dormer Pramet A940 3/32 Inch HSS-E High-Performance Multi-Application Straight Shank Long Series Drill, DIN/ANSI compliant for reliable, versatile metalworking across plates, tubes, and profiles. Designed for precision, speed, and depth, this drill is built to elevate your fabrication or repair projects from good to consistently excellent.

Why the A940 stands out in demanding metalworking

• 130-degree point for self-centering and smoother entry — reduces push force, minimizes wandering, and helps you start holes cleanly in tough materials.
• Bright finish — minimizes material sticking to the cutting edge, promoting faster chip flow and cleaner holes even in reactive alloys.
• Parabolic flute design — engineered to evacuate chips efficiently and enable deep-hole drilling in a single pass, cutting cycle time and reducing tool wear.
• Premium HSS-E material (cobalt-enriched) — hardened for durability across steel, aluminum, and stainless steel, delivering consistent hole quality under high-speed conditions.
• Long-series, straight-shank geometry — compatible with standard chucks and drill presses, offering extended reach without compromising rigidity or accuracy.
• High-speed performance with tight tolerances — designed to produce accurate holes with H10 tolerance even as speeds and feeds climb, making it ideal for precision work and repeatable results.

Ideal use cases

• Fabrication shops drilling through mild steel, stainless steel, and aluminum where accuracy and depth matter.
• Automotive or aerospace fixtures requiring deep, clean holes without multiple passes.
• Machining setups and repair scenarios where a single, reliable drilling cycle saves time and reduces tool wear.
• Shop environments that demand DIN/ANSI standard tooling for interchangeability and traceability.

How to get the best results

• Match speed and feed to material type: higher speeds with conservative feeds for aluminum; slightly slower feeds with generous chip removal when drilling steel or stainless.
• Apply light, steady cutting pressure and let the parabolic flutes carry the chip away from the cutting edge.
• Use a piercing technique with the 130-degree point to establish a clean initiation and prevent walks or walking burrs.
• Keep the drill sharp and well-lubricated to preserve hole quality and extend tool life in tough alloys.
• Peck drilling can help long holes: retract periodically to clear chips and prevent clogging in deep-hole applications.
