Dormer Pramet A110 17/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 17/32 inch HSS ST Straight Shank Long Series Drill, a purpose-built solution for deep-hole drilling and demanding workshop tasks. Crafted to DIN 340 standards, this drill pairs a robust geometry with practical design to deliver dependable performance in both handheld and machine setups.

• 118-degree conventional point — a strong, self-centering tip that starts cleanly and re-sharpening remains straightforward, delivering precise holes with minimal wandering.
• Steam oxide finish — a low-friction surface that helps prevent workpiece material from sticking to the cutting edge, reducing heat buildup and promoting consistent chip control.
• Long length series — engineered for deeper holes and applications where extended reach is essential, enabling you to drilling through thicker sections without swapping tools.
• Premium HSS material — versatile across materials such as steel, stainless steel, and aluminum, providing reliable performance and stable hole geometry across diverse projects.
• Straight shank — compatible with a wide range of chucks and spindles, offering straightforward mounting and stable cutting action in both hand-held and CNC/machine drilling contexts.

Use cases that benefit from this drill’s design:

• Deep through-holes in automotive components, fixtures, and jig setups where reach is a limiter with standard drills.
• Long-reach drilling in fabrication and assembly work where maintaining hole accuracy and finish matters.
• Applications that require reliable re-sharp capability, thanks to the 118° point that’s easy to restore with a quick grind.

Practical tips for best results:

• Start with a sharp edge and use a light feed to establish a precise pilot hole before deeper drilling.
• Maintain proper lubrication or cutting fluid to minimize heat, especially when drilling stainless steel or alloys.
• Regularly inspect the flute edges for wear; the long-length design rewards timely re-sharpening to preserve hole quality.
• Leverage the DIN 340 compatibility for straightforward tool changes in mixed-tooling setups, ensuring consistent performance across machines and handheld drilling.

The Dormer Pramet A110 17/32 inch HSS ST Straight Shank Long Series Drill is built for professionals who need depth, reliability, and versatility in a single tool. Whether you’re enlarging or deepening holes in thick workpieces or performing precise drilling on intricate assemblies, this long-series drill delivers trustworthy results time after time.
