Description
The Dormer Pramet A777 27/64 Inch HSS-E Straight Shank Jobber Drill (DIN 338) is a premium, cobalt-enhanced drill built for demanding metalworking tasks. Designed for steel, aluminium, and stainless steel, it starts holes cleanly and stays sharp longer, making it a reliable choice for engineers, machinists, tradespeople, and serious hobbyists.
- 135° split point for self-centering: Ensures precise hole initiation with less push force, reducing wandering and speeding up setup for faster, more consistent drilling results.
- Bronze oxide finish for smooth cutting: Helps prevent workpiece material from sticking to the edge, improving chip flow and extending tool life in tough jobs.
- Premium HSCO material with heavy‑duty design: cobalt-enhanced construction delivers reliable performance across a range of materials, including steel, aluminium, and stainless steel, even in difficult, high‑demand applications.
This straight‑shank drill is built to fit standard drill chucks and DIN 338 specifications, offering dependable accuracy and finish quality across multiple projects. Choose the A777 for consistently clean holes, reduced downtime, and a tool you can trust in busy workshops and precision work alike.
