Dormer Pramet A110 1/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 1/32 Inch HSS ST Straight Shank Long Series Drill (DIN 340) is built for precision, durability, and reach in metalworking tasks. Designed for small-diameter work, this drill delivers clean, accurate holes in a variety of materials, from steel to aluminum and stainless steel, with reliable performance in both handheld and machine setups.

Key features that matter in real-world drilling

• 118-degree conventional point – a strong, self-centering tip that reduces wandering and is easy to re-sharpen, so you can maintain accurate starts over many holes.
• Steam oxide finish – a low-friction coating that helps prevent workpiece material from sticking to the cutting edge, promoting smoother cuts and longer edge life.
• Long length series – optimized for drilling deeper holes and accessing hard‑to‑reach areas without repositioning your setup, ideal for intricate or recessed workpieces.
• Premium HSS material – high-speed steel provides durability and versatility, suitable for drilling steel, aluminum, stainless steel, and other common metals with consistent results.
• Straight shank, DIN 340 compatibility – broad compatibility with standard chucks and drilling machines, delivering solid grip and reliable performance across handheld and machine applications.

Ideal uses and practical advantages

The 1/32 inch diameter is perfect for pilot holes, precise holes in thin sections, and delicate work where control matters. Whether you’re assembling small mechanical components, fabricating enclosures, or tackling hobbyist projects, this drill’s balanced geometry — combined with the A110’s long reach — minimizes hole misalignment and reduces the need for rework. It shines in both manual drilling tasks and automated setups, offering predictable hole quality and repeatable results.

Why choose this drill over alternatives

What sets this drill apart is the thoughtful combination of an easily re-sharpened 118° point, a steam oxide finish to cut down sticking and galling, and a long-length design that preserves rigidity and accuracy in deep-hole scenarios. The result is consistent hole geometry, less tool life downtime, and improved productivity for small-diameter metal drilling jobs. Its universal straight shank and DIN 340 specification ensure dependable performance across a wide range of machines, making it a reliable workhorse in any metal shop or home workshop.

To get the best results, use with appropriate cutting fluid or lubricant, start with a light touch to establish the pilot hole, and maintain steady feed pressure. For deeper holes, periodically withdraw the bit to clear chips and prevent binding, and re-sharpen as needed to sustain edge quality and accuracy.
