  • Portable adjustable cutting apparatus for cutting and shaping sink holes in stone countertops
    Patent number: 9533430
    Abstract: Three portable apparatus are operative sequentially to cut and shape sink holes in stone countertops, each adjustably engaging with the same prior art sink template to control reveal. A first apparatus makes linear cuts in stone using a disk-shaped saw blade while adjustable flange wheels follow the template. A lift biases the disk-shaped saw blade out of the stone when not cutting. A second apparatus cuts inside corners and curves using a contour saw blade while adjustable guide fences follow the template. The spindle shaft angle can be varied to leave a finished side vertical. A third polishing apparatus uses an abrasive drum and an adjustable rotating rub collar around the drum abrasive that operatively changes a distance between the drum abrasive and sink template to adjust for different diameter drums and adjust as the drum abrasive diameter changes due to wear.
