A flat wood drill bit has the ability to cut through the material and form a wider, flat-bottom hole with an additional mini hole at the center. The center part of the bit helps us mark the location we want to cut through, while both side parts help us to widen the hole. As a result, this drill bits type is most effective when the screw has a shape that needs to be recessed in the bottom of the hole. At SIDS DIY, we provide you with a variety of flat wood drill bits of different sizes from 12 to 35mm.
