The Dormer Pramet A940 13/32 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill is engineered for precision, versatility, and dependable performance across a range of metals. Designed to handle demanding drilling tasks in steel, aluminum, and stainless steel, this drill delivers consistently clean, accurate holes even at higher speeds and feeds. Key features that distinguish the A940: - 130° point for effortless self-centering: The sharp, precise tip reduces the pushing force required and helps lock the drill into the workpiece from the start, minimizing walk and chatter. - Bright, non-stick finish: The enhanced surface finish reduces material adhesion on the cutting edge, cutting setup time and improving hole quality in challenging alloys. - Parabolic flute design for deep-hole capability: The special flute geometry efficiently evacuates chips, enabling longer, deeper holes in a single pass without sacrificing accuracy. - Premium HSS-E material: Combines toughness and wear resistance to drill a broad spectrum of metals—from carbon and alloy steels to aluminum and stainless steel—without frequent tool changes. - High-performance, DIN/ANSI-compliant straight shank: Long-series geometry supports stability in longer drilling applications and fits standard chucks and holders with reliability and repeatable results. - H10 hole tolerance capability: Engineered to achieve tight tolerances at typical shop speeds, delivering holes that meet or exceed precision requirements for mating parts and assemblies. Who this is for: - Machine shops, fabrication shops, and job sites that demand repeatable, high-precision holes in multiple materials. - Operators needing reliable performance at higher speeds and feeds without sacrificing hole quality or tool life. - Engineering teams that require a single drill that can tackle steel, aluminum, and stainless steel with consistent results. Use cases and practical insights: - Deep-hole drilling in thick steel sections or aluminum profiles benefits from the drill’s parabolic flute, reducing the need for pecking and re-entry. - When switching materials in a single job (e.g., drilling through a steel frame then into aluminum fixtures), the A940 maintains edge stability and minimizes thermal buildup thanks to its HSS-E composition and bright finish. - For DIN/ANSI-standard setups, this straight-shank long-series drill remains stable at high RPMs, preserving hole concentricity and reducing runout-related defects. In short, the Dormer Pramet A940 13/32 Inch HSS-E High Perf Multi-App Straight Shank Long Series Drill is built for serious metalworking demands. It delivers precise, deep-hole capability across a range of materials, with a design that reduces resistance, minimizes material sticking, and maintains accuracy from initial contact through to completion.
