Dormer Pramet A110 1/16 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Meet the Dormer Pramet A110 1/16 Inch HSS ST Straight Shank Long Series Drill DIN 340—a purpose-built, long-reach drill designed for dependable metalworking where depth and precision matter. This is the core tool you reach for when you need to drill deeper holes without compromising accuracy or stability.

• 1/16 inch diameter, long-series design — a straight shank drill with extended flute and overall length, crafted for deeper holes and increased reach. DIN 340 conformity ensures compatibility with standard chucks and machines, making it a reliable choice for both handheld and benchtop drilling setups.
• 118° conventional point — a robust, easy-to-reground tip that starts true and resists wandering, helping you achieve clean entry and consistent hole geometry even in tough metals.
• Steam-tempered finish — the steam oxide surface minimizes material sticking to the cutting edge, improves chip flow, and supports steady performance across multiple holes in steel and other alloys.
• Premium HSS material — engineered for versatility across common metals, including steel, aluminum, and stainless steel, delivering reliable cutting action and reasonable wear resistance for everyday fabrication tasks.
• Versatility in use — ideal for a wide range of applications, from workshop repairs to production setups, where a long-reach drill that maintains rigidity and edge life is essential for keeping workflows smooth.

Practical tip: for steel, pair the A110 drill with appropriate cutting fluid and maintain a steady feed rate to minimize heat build-up. When drilling aluminum, moderate speed and consistent chip evacuation help prevent built-up edges. If the cutting edge dulls, follow proper re-grinding steps to restore the 118° point and extend the tool’s life, keeping your projects on schedule without frequent tool changes.
