Dormer Pramet A110 8.80 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 8.80 mm HSS ST Straight Shank Long Series Drill, DIN 340, is a purpose-built drilling solution for engineers and technicians who tackle deep-hole tasks with consistent results. This long-series design offers extended reach without sacrificing accuracy, making it ideal for working through thicker materials or when access is limited.

• 118-degree conventional point — a robust tip that starts holes cleanly every time, minimizes wandering, and is easy to re-sharpen to extend tool life in demanding production or DIY environments.
• Steam oxide finish — engineered to reduce friction at the cutting edge and prevent workpiece material from sticking, which translates to smoother chip flow and quieter cutting action.
• Long length series — specifically recommended for drilling deeper holes or reaching into recessed areas where standard drills can't reach, without compromising rigidity or control.
• Premium HSS material — high-speed steel chosen for durability and wear resistance, capable of handling a variety of materials from steel and stainless to aluminum with reliable hole size integrity.
• DIN 340 compatibility — standardized form and geometry ensure consistent fit in common chucks and machine spindles, reducing setup time and improving interchangeability across tools.
• Versatile performance — suitable for a wide range of applications, whether you’re drilling with a handheld drill for on-site tasks or using a machine drill in a workshop setting.
• Regrindable edge geometry — designed for multiple regrinds, letting you refresh the cutting edge to extend life and maintain precision across production runs.

In practice, the A110 8.80 mm drill shines in fabrication, maintenance, and general engineering workflows where deep-hole capability and dependable performance matter. The straight shank provides secure grip in standard chucks, while the long-series geometry delivers consistent hole diameters and clean finishes even in tougher materials. Whether you’re preparing mounting holes in steel frames, drilling through extrusions, or creating access holes in housings, this drill delivers predictable results with less rework.

The Dormer Pramet tooling philosophy centers on reliability and repeatability. This 8.80 mm HSS drill is designed to be a workhorse in your toolkit—easy to sharpen, resilient under heat, and capable of delivering steady performance when the job demands extended reach and steadfast accuracy.
