Dormer Pramet A110 9.80 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 9.80 mm HSS Straight Shank Long Series Drill DIN 340 is purpose-built for precise, deep-hole drilling in metalworking environments. Designed to handle demanding tasks with reliability, this drill bit blends a robust point geometry with durable HSS core to deliver consistent performance from first cut to last chip.

• 118-degree conventional point — a strong, self‑centering tip that reduces wandering and promotes accurate hole starts. The point is straightforward to re‑grind, helping you extend the life of the tool between sharpening sessions.
• Steam oxide finish — a low-friction surface treatment that minimizes workpiece material from sticking to the edge. This improves chip clearance and reduces built-up edge, leading to smoother drilling and fewer interruptions.
• Long length series — optimized for deeper holes and applications where additional reach is essential. The extended flute length maintains rigidity and straightness, so you can drill through thicker sections or into recessed areas with confidence.
• Premium HSS material — crafted from high-speed steel to withstand heat and provide versatile performance across a range of metals, including steel, aluminium, and stainless steel. The material combines durability with predictable cutting action in everyday workshop tasks.
• Straight shank — compatible with a wide array of hand-held drills and machine spindles. The straight shank offers stable gripping and consistent alignment, reducing runout during heavy drilling.
• DIN 340 compliant — built to standard specifications for reliable interchangeability with compatible holders and tooling systems, ensuring you can integrate this drill into existing setups without hassle.
• Versatile application — ideal for general-purpose drilling in machine tools and portable drills alike. Whether you’re fabricating steel frames, fabricating aluminum components, or doing maintenance on stainless assemblies, this drill handles a variety of projects with a single, dependable bit.

Why choose the A110 9.80 mm drill for your shop?

• Consolidate your toolkit with a long-reach drill that delivers accurate starts and clean holes in a range of metals, reducing the need for multiple drill sizes.
• Rely on a dependable grindability profile: the 118° point is easy to re-sharpen, helping you maintain peak performance without frequent tool replacement.
• Benefit from improved chip evacuation and reduced sticking thanks to the steam oxide finish, which translates to smoother operation and less downtime.

Practical use and care tips

To get the most from this drill, clamp the workpiece securely and use appropriate feeds and speeds for the material being drilled. Apply a suitable cutting fluid when drilling steel or stainless to minimize heat and extend tool life. Start with a pilot approach if drilling thicker sections, maintain steady pressure, and withdraw the bit periodically to clear chips. When signs of dullness appear, re-sharpen or replace the bit to preserve hole quality and prevent excessive wear.

Ideal for metalworkers, machinists, and serious hobbyists who need a reliable, long-reach drill that performs consistently across steel, aluminium, and stainless steel. The Dormer Pramet A110 drill is a smart choice for deep-hole tasks and long-reach drilling scenarios where every cut counts.
