Dormer Pramet A940 5.80 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

When you need precision, reliability, and versatility in metalworking, the Dormer Pramet A940 5.80 mm HSS-E High Performance Multi-Application Straight Shank Long Series Drill is the tool you reach for first. Engineered for engineers and machinists who demand consistent hole quality across a range of materials, this drill bit is built to tackle diverse tasks without swapping tools.

Key features that differentiate this drill

• 130-degree point: A self-centering tip that reduces the starting push force, helping you establish accurate center marks and minimize wandering during entry.
• Bright finish: The bright coating minimizes material sticking to the cutting edge, improving chip control and reducing downtime from built-up edge.
• Parabolic flute design: Special flute geometry designed to evacuate chips efficiently, enabling deeper holes in a single pass and maintaining straight, stable holes even in challenging materials.
• Premium HSS-E material: High-speed steel with enhanced properties for drilling a wide range of metals, including steel, aluminum, and stainless steel, offering extended tool life and tough performance.
• Long series, straight shank and DIN/ANSI compatibility: Designed to fit standard chucks and collets, providing reliable grip and runout control for accurate hole placement.
• High-performance drilling: Capable of high speeds and feeds with consistent hole quality and precision tolerance (H10) for dependable, repeatable results.

Who benefits most from the A940? Job shops, fabrication shops, and maintenance teams that require a single drill that can handle multiple materials and reach deeper holes without changing tools. If you’re drilling steel for structural components, aluminum for lightweight assemblies, or stainless steel for corrosion-resistant parts, this drill delivers predictable results with every pass.

Practical tips for best results: - Match speeds and feeds to material type and thickness; start at moderate speeds and increase as needed while monitoring chip formation. - Use ample lubrication or cooling to extend flank life and reduce built-up edge, especially in stainless steel. - Secure the workpiece firmly and use proper clamping to prevent deflection at depth. - For deep holes, rely on the parabolic flute to maintain chip clearance and consistent hole diameter.

Firmly anchored in the DIN/ANSI standard ecosystem, the Dormer Pramet A940 drill is a dependable, long-term addition to your toolbox—ready to tackle a wide range of drilling tasks with precision and efficiency.
