Abstract:

A dustless hole saw includes a compressible dust catcher surrounding a saw blade removably affixed to a rotating circular frame. The generally cylindrical compressible boot has an end plate at the end furthest from the saw blade. One end of a generally cylindrical sleeve is affixed to the end plate and the other is attachable to a drill motor. The boot encloses the chuck of the drill motor and has an access opening in its sidewall to permit adjustment of the chuck. The end plate may be at least partially transparent to permit the operator to align the pilot drill of the saw. As the hole saw cuts into the work surface, the boot is pressed against the surface outside the perimeter of the cut catching the dust and debris created by the cutting operation.
