Multipurpose Hole Cutters
Multipurpose hole cutters are used on single or mixed materials, such as wood, metal, plastic, and nail-embedded wood. Hole cutters have a hollow center and a number of cutting teeth similar to those found on a circular saw blade. They cut holes by removing a section of material while leaving the core whole. This speeds drilling and allows larger holes to be made using a handheld power drill than is possible using a standard drill bit.
