Dormer Pramet A940 5.40 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

Meet the Dormer Pramet A940 5.40 mm HSS-E High-Perf Multi-App Straight Shank Long Series Drill DIN/ANSI—an all‑purpose workhorse engineered for machine shops, fabrication floors, and maintenance teams that demand consistent, commercial‑grade hole quality across a variety of materials. This drill combines precision geometry with robust materials to deliver dependable performance in real-world drilling tasks.

• 130° point — promotes quick self‑centering and lowers the push force required to start a hole, helping you achieve accurate starts even on tough or slippery surfaces.
• Bright finish — minimizes sticking of workpiece material to the cutting edge, reducing built‑up edge and improving chip flow for cleaner holes.
• Parabolic flute design — engineered to evacuate chips efficiently, enabling deeper holes in a single pass with reduced vibration and superior hole quality.
• Premium HSS‑E material — high‑speed steel with enhanced wear resistance, suitable for drilling steel, aluminum, stainless steel, and other common engineering materials without frequent tool changes.
• Long series straight shank — designed for stability in standard drill chucks and milling machines, ensuring consistent alignment and reliable performance at higher speeds and feeds.
• High performance with H10 hole tolerance — delivers precise hole diameters and smooth finishes even at elevated cutting data, reducing secondary operations and rework.
• DIN/ANSI compatibility — built to standard dimensions for easy interchangeability in existing tool lines and fixtures.

Designed for versatility, the A940 thrives in both lightweight and more demanding drilling scenarios. Use it for quick pilot holes in sheet metal, through‑holes in thicker workpieces, or long reach tasks where a reliable, straight hole is essential. It’s an ideal choice for automotive components, general mechanical fabrication, and maintenance environments where durability and precision matter most.

Practical tips for best results: - Select speeds and feeds tuned to the material: faster speeds for aluminum, moderate speeds for steel, and conservative speeds for stainless to prevent overheating. - Use light lubrication or coolant to extend edge life and improve surface finish. - For deep holes, employ a peck drilling approach to clear chips and maintain hole straightness.
