Hole Saws








Additional Information

HOLE SAWS

A hole saw drills large holes for installing door hardware or creating a pass-through for wiring. It also creates a plug of waste material; a cut-out in the side of the saw cylinder allows you to push it out. Typically, a hole saw attached to an arbor or mandrel, which includes a shank. The arbor also holds a pilot bit for centering and steadying the cutting blade. Some smaller hole saws have a built-in shank and don't use a pilot bit. A bi-metal hole saw cuts through wood and metal. A hole saw with a carbide edge works on heavier materials such as ceramic tile and masonry. A hole saw with a diamond edge also works on tile and masonry but cuts faster than carbide models.
