RemGrit 2" Hole Saw can be used to cut ceramic tile, marble, slate, fiberglass, laminates, and composites. It features a patented design that does not require a separate mandrel or pilot drill. The tungsten carbide grit cutting edge and continuous edge design produce exceptionally smooth cuts, and there are no teeth to dull or chip. The saw has a 1" depth of cut and is perfect for do-it-yourself ceramic tile projects.
