The Annular Hole Cutter HSS 60 x 30mm Weld Shank 19.05mm is a high-speed steel (HSS) cutting tool designed for creating precise, clean holes in metal materials. The 60 x 30mm dimensions refer to the outer diameter and cutting depth of the cutter. The weld shank means the cutter is mounted onto a shank that is welded, offering greater durability and stability during use. The 19.05mm refers to the shank size (approximately 3/4 inch), ensuring compatibility with most machines and drill presses. This tool is often used in industrial applications, especially for tasks requiring large, accurate holes in thick metal.
