Dormer Pramet A110 8.20 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

When your projects demand deep, precise holes with dependable performance, the Dormer Pramet A110 8.20 mm HSS ST Straight Shank Long Series Drill DIN 340 is engineered to deliver. Built for metalworking tasks that require reach without sacrificing accuracy, this drill combines a robust carbide-friendly core with practical features that keep you drilling longer between sharpenings.

Key features that matter in real-world drilling

• 118° conventional point — delivers a strong, self-centering start that resists wandering and is straightforward to re-grind, helping you maintain precise hole alignment across multiple jobs.
• Steam oxide finish — minimizes material sticking to the cutting edge, reducing built-up edge and promoting cleaner hole formation for smoother finishes.
• Long length series — extended flute length provides true reach for deep-hole drilling and through-holes in thick stock, castings, or assemblies where standard drills can’t reach.
• Premium HSS material — versatile enough to handle steel, aluminium, and stainless steel with reliable toughness, improving productivity in mixed-material environments.
• Straight shank — broad compatibility with a wide range of chucks and collets, ensuring stable centering and minimal runout in both handheld and machine-driven setups.
• DIN 340 conformity — standardized sizing guarantees interchangeability and predictable performance across brands and tooling systems.
• Versatility for demanding workflows — suitable for use in hand-held drills, drill presses, and machining centers, making it a trusted choice in workshops and production lines alike.

Who benefits from the A110 drill? Professionals in fabrication, maintenance, and engineering, as well as serious hobbyists who tackle metalworking projects that require deep holes, precise starting geometry, and reliable edge life. The combination of a re-grindable 118° point, steam oxide finish, and long reach translates into fewer tool changes and more consistent results across jobs.

Practical use cases

• Deep-hole drilling in steel brackets, engine housings, or structural components where a standard drill length would fall short.
• Through-holes in aluminum extrusions and stainless assemblies that demand accurate alignment and a clean finish.
• Machine- or hand-held drilling in thick materials where stable guidance and edge life are critical to maintaining production schedules.

Tips for best results

• Peck drilling and steady feeds help evacuate chips when drilling for depth, reducing heat and extending tool life.
• Ensure the drill is true in the chuck or collet to maximize the benefits of the straight shank and minimize runout.
• Use appropriate cutting fluid or lubrication to manage heat, especially when drilling stainless steel or other harder materials.
• Keep the edge sharp; the 118° point is designed for easy re-grinding to restore performance without compromising geometry.
