The main function of a masonry drill bit is to make holes and cut through solid concrete, natural stone, brick, wood, glass, and plastic. Knowing about the right drill bit is not as easy as you think. Even choosing the wrong bit can do some major damage to both the concrete surface and the bit. There are masonry bits and wood boring bits. First of all, identify the shape of the tip and the style. If the tip is arrowhead-shaped, then it’s made as a masonry bit.
