Description
The Dormer Pramet A900 12.50 mm HSS-E High Performance Multi-Application Straight Shank Jobber Drill is a versatile DIN/ANSI drilling tool designed for professionals who need reliable holemaking across a range of metals. Crafted with premium HSS-E, it delivers consistent performance in steel, aluminium, and stainless steel, making it a dependable choice for workshops, fabrication shops, and on-site projects.
Its design focuses on fast, accurate starts and clean finishes: a 130° point helps with self-centering and reduces push force, a bright finish minimizes material buildup on the cutting edge, and a parabolic flute enables deeper holes in a single pass for improved efficiency.
- 130° Self-Centering Point: Promotes clean starts, minimizes wandering, and reduces the thrust needed to begin cutting, boosting first-pass accuracy.
- Parabolic Flute Design for Deeper Holes in One Pass: Enhances chip evacuation and allows drilling deeper with fewer passes, increasing productivity and hole quality.
- Premium HSS-E for Wide Material Range: Versatile across steel, aluminium, and stainless steel, delivering high-quality, accurate holes even at higher speeds and feeds with H10 hole tolerance.
This drill helps you streamline workflows by reducing setup time, lowering the risk of rework, and delivering repeatable hole sizes to tight tolerances. The robust HSS-E construction resists wear in demanding materials, while the straight shank and DIN/ANSI compatibility ensure a reliable fit in standard chucks and holders. Whether you’re tackling soft alloys or hardened steels, this multi-application drill keeps production moving and results consistent.
