Pilot drill with 5/8" thread designed for crown drills with a diameter of more than 38 mm (large drill diameters require pilotós having shanks. Their absence, with high torque, can cause the thread to break). Thanks to the use of a pilot drill with an HSS tip, it is possible to drill in wood and metal.
After the drill wears out, it is possible to replace it. Yato offers guide drills YT-43994.
