- If you have drilled a piece of wood and came up short or had to somehow line it up from the other side and attempt to correctly drill, then this drill bit set is for you. Each bit in the set is approximately 12" long and they are made from high speed steel. Typically brad point drill bits are perfect for drilling wood, plastic and some composite materials. Brad points have a sharp point on the tip, which prevents the bit from "walking" like standard twist bits tend to do.
