Dormer Pramet A940 12.00 mm HSS-E High Performance Multi-App Straight Shank Long Series Drill DIN/ANSI is built for serious metalworking demands. This straight‑shank long‑series drill blends precision, durability, and versatility, making it a dependable choice for a wide range of materials and applications.

Engineered for accuracy and productivity, the A940 features a 130° point that promotes self‑centering and reduces the push force required to start holes. The result is cleaner entry and less wandering, even when drilling challenging materials or tight tolerances.

• 130-degree point for self-centering and lower starting forces, helping you achieve true holes from the first pass.
• Bright finish minimizes built‑up edge and prevents workpiece material from sticking to the cutting edge, improving chip evacuation and surface finish.
• Parabolic flute design enables deep-hole drilling in a single pass, reducing tool changes and increasing throughput on thick plates and blocks.
• Premium HSS-E (cobalt-enriched) material offers enhanced wear resistance and toughness across a broad material range—including steel, aluminum, and stainless steel—without sacrificing edge life.
• Multi-application capability makes it a versatile solution for through‑hole and blind‑hole work across multiple metals, with consistent hole quality.
• Long series, straight shank delivers rigid engagement with common chucks and holders, minimizing runout for more accurate holes in production environments.
• High-precision hole tolerance (h10) ensures consistent diameters, better fit for mating parts, and reliable assembly in engineering projects.

This drill is ideal for workshop and factory settings where reliability and performance matter. Use appropriate cutting fluid to maintain edge life, match speed and feed to the material, and consider pilot or step drilling for thicker workpieces to maximize accuracy and productivity.

Whether you’re drilling into steel, aluminum, or stainless components, the Dormer Pramet A940 12.00 mm HSS-E drill delivers repeatable, high-quality holes with minimal fuss—making it a practical cornerstone for any precision machining toolkit.
