The HiKOKI 780137 is a combined drill and tap designed to handle both drilling and threading in a single operation, which streamlines assembly and repair work in metals. Made from high-speed steel (HSS), this tool is built for durability and efficiency when creating M12 metric threads. It features a 1/4'' hexagonal shank that ensures a secure fit in compatible tool holders, while the 18 mm useful length provides the necessary reach for your threading tasks. This 2-in-1 solution is particularly useful for technicians and hobbyists who want to reduce the number of tool changes during their workflow.
