Dormer Pramet A110 7.75 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 7.75 mm HSS ST Straight Shank Long Series Drill, DIN 340 is purpose-built for deep-hole drilling with reliable performance in a wide range of metals. This long-reach HSS drill delivers a precise, dependable cut from first hole to last, making it a staple for fabrication, maintenance, and production environments where depth and reach matter.

118° conventional point for fast, accurate starts — The A110 features a robust 118-degree point that centers quickly and resists wandering, improving hole location on the first pass. Best of all, the point is easy to re-grind, extending tool life and keeping downtime to a minimum.

Steam oxide finish for smoother cuts — The steam-oxide coating minimizes material adhesion at the cutting edge, reducing built-up edge and chatter. This means cleaner holes, less frequent tool cleaning, and more consistent hole diameters across multiple passes.

Long length series for deeper holes and increased reach — When you’re drilling into thick workpieces or fixtures that require extended reach, the long-series design keeps the flute fully engaged, delivering steady chip removal and stable cutting action without sacrificing rigidity.

Premium HSS material for versatile metalwork — Constructed from high-speed steel, this drill handles steel, aluminum, and stainless steel with strong wear resistance and reliability. Whether you’re drilling structural steel, aluminum brackets, or Stainless components, this bit maintains sharpness longer and tolerates higher cutting speeds.

Versatility across hand-held and machine applications — Whether loaded in a portable drill or a drill press, the A110 enables consistent results in manual operations and automated setups. Its straight shank provides universal compatibility with collets and chucks, simplifying tool selection across different machines.

Use cases span from automotive chassis fabrication and equipment maintenance to metal fabrication and general engineering. For best results, pair with appropriate cutting speeds and lubrication, start with a stable pilot hole if needed, and re-sharpen the point when wear becomes noticeable to maintain optimal chip evacuation and hole quality.
