Description

The Dormer Pramet A777 9.20 mm HSS-E Straight Shank Jobber Drill (DIN 338) is a robust, versatile tool designed for professionals and hobbyists who work with metal. Built for precision in everyday drilling tasks, it delivers clean, accurate holes across a range of materials when used with standard drill chucks.

Designed for demanding applications, the A777 features a 135° split point for self-centering and easier starting, plus a bronze oxide finish that helps keep the cutting edge from sticking to workpiece material. Crafted with premium HSCO material and a heavy-duty design, it delivers reliable performance when drilling steel, aluminium, and stainless steel, making it well-suited for tough jobs and long runs.

  • 135° split point for self-centering and reduced push force: Starts holes true with less wandering, enabling faster, cleaner drilling and less operator effort.
  • Bronze oxide finish reduces sticking and enhances edge life: Minimizes friction and buildup on the cutting edge for smoother cuts and fewer feed-rate changes.
  • Premium HSCO material with heavy-duty design: Drills a wide range of materials — steel, aluminium, stainless steel — with long tool life, plus a straight DIN 338 shank for broad chuck compatibility.

This drill is designed to streamline metalworking workflows by delivering consistent results, reducing downtime from tool changes, and providing dependable performance across common engineering and fabrication tasks. Its durable construction and versatile material compatibility help you finish more work with fewer tools, making it a reliable choice for workshop, job site, and production environments.
