Combine our core drills with drilling machines that you are already using every day – for materials such as structural steels, chrome-nickel steels and non-ferrous metals, such as aluminum or CuZn alloys. With the thread holder M18 X 6P 1.5 the carbide-tipped Alfra specialists for special tasks are also fitting on Hitachi machines. You profit from all advantages of this series: For example the Alfra- chip breaker system with pre-, middle- and re-cutter against jamming. Further unique selling points: High concentricity, immediate centering, no 'running' of the bore and the fast core removal by means of ejector pin. In addition, the carbide-tipped drills convince with their very low energy consumption.
