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 SDS end, it is possible to use the drill for many devices; no reduction is necessary.
The SDS end does not carry the impact, so working with devices where it is not possible to turn off the impact will not damage the crown.
After the drill wears out, it is possible to replace it. Yato offers guide drills YT-43995.
Usage warnings:
Use of hand tools may be dangerous! Always use personal protection equipment at work. Use only proper undamaged tools. Select the type and size of tool according to intended application. Do not overload tools. Keep tools away from children. Use tools with proper care.
