ABSTRACT:
A dry-wall cutting tool is described. It has a block-like configuration and is designed to slide over the edge of the drywall and to cut both sides of the drywall to the same distance from the edge and at the same time as it does so. The depth of the cut (i.e. distance from the edge of the drywall being cut) can be controllably varied considerably and it will typically be between 1/8 inch and 6 inches deep from the edge of the drywall that is being cut. The cutting tool has vertical threaded shafts upon which are mounted cutting wheels and rubber or nylon rollers, with ball bearings between the shafts and the cutting wheels and rollers. Due to its construction the twin cutting can be done quickly and with little manual effort or force.
