The Dormer Pramet A777 15.50 mm HSS-E Straight Shank Jobber Drill (DIN 338) is built for dependable hole making in a wide range of metals. Ideal for engineers, machinists, tradespeople, and hobbyists, it delivers precise starting holes and consistent finishes in everyday and demanding drilling tasks.
Designed for versatile use, this drill features a 135° split point for quick, self-centering entry, a bronze oxide finish to minimize sticking and built-up edge, and a robust cobalt-based HSCO composition that can handle steel, aluminium, and stainless steel. The heavy-duty design ensures it stands up to challenging materials and applications, making it a reliable choice in any shop.
- 135° Split Point for Self-Centering and Easy Start: Reduces wandering at initial entry and lowers the push force required, helping you drill cleaner holes with less effort.
- Bronze Oxide Finish for Reduced Build-Up: Minimizes material adhesion to the cutting edge, improving hole quality and reducing downtime from rework.
- Premium HSCO Material with Heavy-Duty Design: Offers versatility across steel, aluminium, and stainless steel, while the rugged body is built for demanding materials and long-lasting performance.
This combination of precise starting action, anti-stick coating, and durable cobalt-based construction helps you complete projects faster, with smoother operation and consistently accurate results—whether you're running production drills, performing maintenance, or tackling precision fabrication.
