Dormer Pramet A110 5/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 5/32 Inch HSS ST Straight Shank Long Series Drill (DIN 340). This drill is purpose-built for serious metalworking tasks where depth and reliability matter, delivering clean, accurate holes and long-lasting performance in demanding environments.

Key features that matter in real-world drilling

• 118° conventional point — a strong start that’s easy to re-grind, helping you achieve true hole alignment and extend tool life without sacrificing accuracy.
• Steam oxide finish — reduces chip adhesion and heat buildup at the cutting edge, keeping workpieces from sticking and promoting smoother, cooler drilling in a range of metals.
• Long length series — designed for deeper holes and applications where reach is essential, while maintaining rigidity for controlled cutting in handheld or machine setups.
• Premium HSS material — versatile across steel, aluminium, and stainless steel, offering dependable performance from light fabrication to more demanding structural work.
• Straight shank — compatibility with a wide variety of chucks and spindles, delivering stable guidance and reduced runout in both handheld drills and drill presses.

This drill is ideal for workshops and fabrication shops that frequently need to bore deeper holes in metal components, frames, housings, and panels. Its DIN 340 specification ensures consistent sizing and interchangeability with standard tool holders, so you can rely on predictable results across multiple machines and setups.

Why choose the A110 for your projects? If you’re building or repairing metal assemblies that require precision holes at depth, this long-series drill reduces the need for multiple tools, speeds up your workflow, and provides a robust edge that’s easier to maintain and re-sharpen than many standard bits. The combination of a tough HSS core, a clear point geometry, and a finish that minimizes sticking translates to fewer interruptions and more consistent hole quality—whether you’re drilling through steel components, aluminum brackets, or stainless parts.

Practical tips for best results

• Peck drilling in metals with generous chip clearance prevents heat buildup and prolongs edge life.
• Sharpen the 118° tip with appropriate drill-sharpening equipment when performance declines, rather than forcing the bit to work harder.
• Use a steady feed rate and adequate lubrication to maintain edge integrity during deeper hole drilling.
• Pair with suitable drill chucks or collets that accept a straight shank for optimal alignment and minimal runout.

The Dormer Pramet A110 5/32 Inch HSS ST Straight Shank Long Series Drill is a dependable choice for professionals who value depth, versatility, and consistency in metal drilling tasks. Its robust construction and thoughtful finishing turn practical challenges into efficient, repeatable results.
