About this product
This Irwin step drill bit is designed for precise drilling of round holes in thin materials such as sheet metal, offering 13 hole sizes ranging from 5mm to 35mm (5, 7.5, 10, 13, 16, 19, 21, 23, 26, 29, 31, 33 and 35mm) from a single tool. It features a single flute design for maximum control when drilling sheet metal, ensuring perfectly round holes. The fluted shank helps prevent the bit slipping in the chuck, while a self-centring point avoids walking across the material and removes the need for centre punching. Constructed from industrial grade M7 high-speed steel for durability during use.
