Description
The Dormer Pramet A777 4.40 mm HSS-E straight shank jobber drill (DIN 338) is a reliable metalworking tool designed for precise holes across steel, aluminium, and stainless steel. With a straight shank that fits a wide range of chucks, it’s a dependable choice for engineers, machinists, contractors, and hobbyists who need consistent results in demanding materials.
- 135° Split Point for precise starts: The 135-degree point self-centers at entry, reduces wandering, and lowers push force, helping you start holes cleanly and move quickly through tough or slippery materials.
- Bronze oxide finish for smoother cutting: The anti-stick coating minimizes material buildup on the edge and promotes smoother chip flow, contributing to steadier cuts and easier finishing.
- Premium HSS-E (HSCO) material with heavy-duty design: cobalt-enriched high-speed steel delivers greater wear resistance and heat tolerance, enabling reliable drilling across steel, aluminium, and stainless steel in demanding applications.
This combination of accurate starts, protective finish, and durable construction helps you complete projects faster with fewer re-drills and better hole quality, making it a trusted choice for daily production and precision work alike.
