Dormer Pramet A110 9/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 9/32 Inch HSS Straight Shank Long Series Drill DIN 340 is engineered for serious metalworking needs, delivering efficient, precise drilling with a focus on reach and reliability. This long-series drill bit is purpose-built for deep-hole work and applications where extended access is essential, all while fitting securely in standard chucks thanks to its straight shank design. Key features that matter in real-world drilling: - 118-degree conventional point: Starts clean, penetrates smoothly, and remains stable even in tough materials. The point geometry minimizes wandering on initial contact, helping you hit your mark on the first try and reducing rework. - Steam oxide finish: A practical coating that reduces built-up material on the cutting edge, promoting freer chip evacuation and easier entry. This finish also helps minimize friction, extending tool life in demanding jobs. - Long length series: Specifically chosen when you need added reach without sacrificing performance. Ideal for deep holes, cavity drilling, and through-holes where standard-length bits struggle to reach. - Premium HSS material: High-speed steel delivers strong cutting performance across a range of metals, including steel, aluminum, and stainless steel. The bit stays sharp longer, tolerates heat well, and remains dependable under heavy use. - Versatile in both handheld and machine setups: The straight shank provides compatibility with a wide array of drill presses, milling machines, and portable drills, making it a flexible choice for workshop layouts and on-site work. - DIN 340 specification: Built to precise standards, ensuring interchangeability with other DIN 340 tooling and consistent performance across brands that meet the same spec. How this drill bit solves common challenges: - Deep-hole drilling without frequent bit changes, enabling faster jobs with fewer interruptions. - Drilling in mixed metals where heat and friction can cause edge buildup; the steam oxide finish helps maintain smooth cutting action. - Tasks that demand a robust, re-sharpenable cutting edge, so you can refocus on precision rather than premature bit replacement. - Workflows that mix handheld operation with machine tooling, thanks to the universal straight shank that fits most chucks and adapters. Practical tips for optimal results: - Use appropriate speeds and feeds for the material you’re drilling; start with conservative speeds and increase gradually as you monitor bite and chip formation. - Apply light cutting fluid or oil to improve lubrication, especially when drilling stainless steel or aluminum, to extend tool life and achieve cleaner holes. - Begin with a light, steady entry to establish the hole, then increase feed rate as the bit seating stabilizes. - For extremely deep holes, consider peck drilling techniques to clear chips and maintain consistent cutting conditions. Designed for professionals and serious hobbyists alike, this drill bit delivers dependable performance in metalworking projects—from fabrication and repair tasks to prototype development. The Dormer Pramet name brings decades of engineering know-how to your workshop, pairing precise DIN 340 specifications with practical, real-world usability. [Logo image]
