The Laser 420 core bit was developed for small diameter drilling and is specific for wet machines with 1/2 gas fitting, both manual and column mounted. Particularly suitable for anchor bolt holes. 420 mm long, available in diameters from 14 to 132 mm. This is a high-performing tool with superior drilling speed, thanks to the particular chemical composition of the segment and the spiral in the body that facilitates the removal of debris from the hole. To use every diameter to the highest performance, it is decisive to have a machine with the power output and rpm suited to that diameter.
