Meet the Dormer Pramet A110 17.50 mm HSS Straight Shank Long Series Drill (DIN 340) – a purpose-built solution for deep-hole precision in a wide range of metals. This drill packs reliability, reach, and versatility into a single, ready-to-work tool that fits both handheld and machine setups.
- 118-degree conventional point: A robust, self-centering tip that starts cleanly and remains easy to re-grind, reducing downtime and keeping holes true.
- Steam oxide finish: Minimizes workpiece material sticking to the cutting edge, promoting smooth chip flow and consistent hole quality even in tougher alloys.
- Long length series: Optimized for drilling deeper holes and reaching into recessed areas without sacrificing rigidity or accuracy.
- Premium HSS material: Delivers dependable performance across a spectrum of metals – steel, aluminium, and stainless steel – with solid wear resistance for busy workshop environments.
- DIN 340 straight shank: Broad compatibility with standard drill chucks and machine spindles, enabling seamless use in both hand-held drills and machining centers.
Designed for professionals who need a single, capable bit for demanding fabrication, maintenance, and engineering tasks. The 17.50 mm diameter makes it ideal for through-holes and larger openings in chassis, frames, and components, while its long form preserves precision in hard-to-reach spaces.
Real-world use cases:
- Deep-hole drilling in automotive restorations or structural fabrication where access is limited.
- Machining stainless steel or alloyed steels in repair shops where reliability and edge life matter.
- Hand-held drilling on projects requiring extended reach without sacrificing hole accuracy.
Practical tips for optimal results: maintain a steady speed and feed, use appropriate cutting fluid especially on stainless steel, and perform regular re-sharpening to preserve the 118-degree geometry. For deep holes, employ a peck drilling approach to clear chips and reduce heat buildup, ensuring clean, straight boreholes each time.
