Hole saw apparatus

摘要

The hole saw apparatus cuts a hole in an existing work object such as drywall, for example. Floor and ceiling cuts as well as other hole cuts are also provided for. The apparatus enables a hole to be cut in the existing work object while guarding against electrical wire damage. The shank may be hexagonal and is chucked into an existing drill. Any existing wire is pulled through the guarded cylinder and even inserted into the sleeve if needed. The apparatus is then free to rotate around the wire and cut the desired hole. Upon completion of hole cutting, the apparatus is pulled away from the work object without damaging the wire. After cutting, a plug usually stays within a hole saw. The sliding mechanism of the apparatus provides for easily removing the cut plug from the hole saw.
