Description
Presenting the Dormer Pramet A110 0.90 mm HSS ST Straight Shank Long Series Drill DIN 340—a micro-drill engineered for precision, reach, and dependable performance in both handheld and machine drilling tasks.
The 118-degree conventional point delivers a strong, stable tip that starts cleanly and can be easily re-ground, helping you maintain accuracy without sacrificing productivity. Built as part of the Long Series, this drill extends your reach for deeper holes and hard-to-access workpieces, making it a reliable choice when space is tight or material thickness demands extra depth.
Crafted from premium HSS (high-speed steel), it’s designed to handle a variety of materials with consistent results. From basic steel and aluminum to more challenging stainless steel, this drill maintains tip integrity and cutting efficiency, reducing dwell time and improving hole quality. The straight shank ensures dependable grip in standard chucks and collets, delivering true concentric drilling and straightforward tool changes in both handheld and machine setups.
Why the A110 stands out
- 0.90 mm diameter—perfect for precision, small-feature drilling where tight tolerances matter.
- Long length design—enables deeper holes and extended reach without sacrificing rigidity.
- 118° conventional point—efficient starts and easier re-grinding to extend tool life.
- Premium HSS material—versatile across steel, aluminium, and stainless steel for a wide range of projects.
- DIN 340 compliance—guaranteed compatibility with standard toolholding and machine tools, ensuring reliable fit and performance.
- Straight shank—stable chuck grip for consistent drilling accuracy in both handheld and machine applications.
Ideal for electronics enclosures, precision prototype work, micro-machining, and any project requiring clean, accurate holes at shallow or modest depths, this drill pairings well with both manual drilling and CNC/fixture-based setups. When you need a dependable micro-drill that won’t compromise on depth or accuracy, the Dormer Pramet A110 is a smart, practical choice.
