The Dormer Pramet A110 2.90 mm HSS ST Straight Shank Long Series Drill DIN 340 is built for precision drilling where depth and reliability matter. This long-series drill combines a robust tip geometry with a versatile shank to tackle deeper holes without compromise.

• 118-degree conventional point – a strong, easy-to-regrind tip that minimizes wandering and maintains accuracy during repetitive drilling tasks.
• Steam oxide finish – a protective coating that helps prevent material from sticking to the cutting edge, delivering cleaner holes and steadier performance across tough metals.
• Long length series – designed for deeper holes and extended reach, reducing the need for auxiliary extensions in both handheld and machine setups.
• Premium HSS material – versatile performance across a wide range of workpieces, including steel, aluminium, and stainless steel, with durability that stands up to repeated use.
• Straight shank – broad compatibility with common chucks and collets, providing reliable grip and straightforward mounting in both manual drills and CNC equipment.
• DIN 340 commitment – built to meet precise dimensional standards for consistent interchangeability and dependable results in professional shops.
• Versatile application – ideal for a variety of metalworking tasks, from fabrication and maintenance to prototype work, where depth and control are essential.

Who benefits most? Automotive and fabrication technicians, machine shops, and serious hobbyists who need to reach through thicker workpieces or fixtures without sacrificing hole quality. The A110 drill delivers clean entry, stable cutting action, and predictable hole geometry across materials like steel, aluminium, and stainless steel, making it a dependable choice for both machine and hand-held drilling workflows.

Practical tips for optimal results: start with a conservative speed and feed to establish a clean cutting zone, use appropriate lubrication or cutting fluid for metals, and re-sharpen the point as needed to extend tool life. The long-series design shines in setups where access is limited or hole depth is critical, helping you complete projects faster with fewer tool changes.
