Diamond 20mm Hole Saw Bit For Electric Drills

High-speed drilling and a long lifespan   The vacuum-brazed diamond side protection offers a smooth and clean cut with minimal chipping. This is a more economic version of the hole saw bit tool, but it still delivers great performance.  Calidad high-speed dry/wet diamond core bits are the most effective solution for drilling holes in kitchen countertops, bath /shower walls for faucets, handles, soap dispensers, and others. They easily tackle tough jobs on dense materials like tile, engineered stone, granite, and other surfaces. High-grade diamonds are brazed firmly on the tool, so it bores through hard substances and stays on the intended cutline without the need for a pilot drill bit.
