Professional, quick, and clean cutting on a variety of materials, including cement board, fibreglass, and hard porcelain tile and stone, is possible with the CorePlus Diamond Holesaw.
Modern vacuum brazing technology guarantees that the diamonds will remain attached for a very long time. Cutting hard tile, stone, and glass requires very little water cooling. On other materials, use completely dry. Smooth, snag-free cutting eliminates the need for secondary finishing. Low torque produced by the incredibly tiny kerf allows for quicker cutting and longer battery life.
