What is a Hole saw?

A hole saw is a tool that can be attached to an electric drill or impact driver to drill holes in wood or thin metal plates. It has a circular and zigzag blade, and it is attached with the blade facing the target. The hole saw also rotates at the speed at which the electric drill rotates to make holes, so work is quick. It can make holes larger than a drill and has a maximum diameter of about 60 mm. Since there is a hole slightly larger than the diameter, it is necessary to adjust it according to the target material.
