Dormer Pramet A110 2.05 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 2.05 mm HSS ST Straight Shank Long Series Drill (DIN 340). Engineered for precision, reach, and reliable performance, this drill bit is built to tackle deep-hole work and demanding metal-cutting tasks with confidence.

Key features that matter in real-world drilling

• 118° conventional point — delivers a strong, self-centering tip that starts cleanly and resists wandering. The geometry is designed for easy re-grinding, so you can restore a sharp edge without sacrificing accuracy.
• Steam oxide finish — a smooth, low-friction coating that helps prevent workpiece material from sticking to the cutting edge, promoting cleaner holes and smoother chip evacuation.
• Long length series — extended flute length for deep-hole drilling and applications where extra reach is essential. Perfect for pockets, blind holes, or operations where space is tight.
• Premium HSS material — high-speed steel ensures robust wear resistance across a range of materials, including steel, aluminum, and stainless steel, while maintaining sharpness over repeated use.
• Versatile, straight-shank design — compatible with handheld drills and machine spindles alike. DIN 340 shank geometry provides consistent fit and reliable performance in common chucks and collets.

Why this drill stands out

The A110 drill is purpose-built for professional workshops and serious hobbyists who need to drill deeper holes without swapping tools. Its combination of a grind-friendly 118° point, anti-sandpaper finish, and long-reach geometry delivers repeatable starts, cleaner holes, and fewer tool changes in the middle of a job. When you’re drilling through diverse materials—steel, aluminum, and stainless steel—you’ll notice how the edge holds up under use, yet remains easy to refresh with a quick re-sharpen.

Ideal use cases

Fabrication shops working on sheet metal and light structural steel will benefit from the long reach on thick sections. Automotive repair and maintenance tasks that require deep-hole access or bottoming operations become more efficient with a single high-quality drill bit. DIY enthusiasts performing precision hole drilling in aluminum or stainless assemblies will appreciate the stable starts and cleaner chip removal.

Practical tips for maximum life and performance

• Maintain the 118° point geometry during re-sharpening to preserve centering and cut accuracy.
• Use proper cutting speeds and feeds for the material you’re drilling to extend edge life.
• Clear chips regularly when drilling deep holes to prevent clogging and overheating.
• Store in a dry, organized toolbox to minimize corrosion and protect the cutting edge.
