Product name:Diamond core drill bits for stone
Size(inch):1-38"
Segment height:10mm
Our diamond stond dry core bit fit on a high-speed angle grinder.
It provides the best cutting performance and can drill through the toughest 1-3/8" granite or engineered stone countertop at the job site without using water. Not only is this convenient but it also increases productivity by cutting down on the amount of clean up needed when using water.
