The Dormer A108 High Speed Steel (HSS) Jobber Drill is designed for drilling stainless steel and other hard materials. It features a split point to start accurately and reduce walking, and a quick spiral flute to aid swarf removal. The drill is built for durability in both DIY and professional applications, with a blue steam-oxide finish that helps minimize built-up edge. Its 135° point provides self-centering and easier penetration, while the external coolant delivery supports lubrication during cutting. The tool is compatible with standard drill chucks and drill presses and meets DIN 338, BS 328, and ISO 235 standards, making it suitable for a range of metalworking tasks.
