Dormer Pramet A110 3/4 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet a reliable workhorse for metalworking: the Dormer Pramet A110 3/4 Inch HSS Straight Shank Long Series Drill, built to tackle deep holes with precision and staying power. Designed to DIN 340 specifications, this drill combines a robust 118-degree conventional point with a long-reach geometry that’s ready for the demands of both handheld and machine drilling.

• 118° conventional point for confident starts and clean, accurate holes. The point geometry minimizes wandering on entry and is easy to re‑grind, so you can extend service life without sacrificing accuracy.
• Steam oxide finish reduces material sticking to the cutting edge, promoting smoother entry and steady chip flow. Less friction means cooler operation and more consistent hole quality.
• Long length series designed for deeper holes and applications that require extended reach. When you’re drilling through thick sections or into hard‑to‑access areas, this drill keeps performance steady from start to finish.
• Premium HSS material delivers dependable performance across a range of common metals—steel, aluminum, and stainless steel—without frequent tool changes. The blend of hardness and toughness supports durable cutting edges and reliable life in real-world work environments.
• Straight shank versatility compatible with a broad spectrum of chucks and collets, ensuring secure grip and minimal runout in both hand-held and machine setups.
• DIN 340 standard ensures consistent diameter and tooling interchangeability, making this drill a dependable choice for mixed fleets and job shops that rely on standard tooling kits.

Who benefits most? This drill is ideal for machinists, fabricators, maintenance technicians, and workshop professionals who need a single, long‑reach solution that can handle multiple materials with predictable results. Use it for deep hole projects in steel frameworks, aluminum components, and stainless parts where clean entry and stable chip evacuation matter most. When you need a drill that combines regrindable performance with extended reach, the A110 long series stands up to daily use without compromising hole integrity.

Practical tips for best results: - Match spindle speed and feed to the material being drilled, following standard HSS drill guidelines. - Use light, steady feed pressure to maintain the 118° point geometry and minimize edge chipping during initial entry. - Apply cutting fluid or light lubrication to reduce friction and extend tool life, especially in stainless steel or thick sections. - For deep holes, rotate the drill intermittently to break chips and prevent clogging, ensuring consistent hole quality from start to finish.
