DAMO Wet Core Drill Bit is designed for drilling the faucet-mounting holes in countertops and vanities. It provides the best cutting performance and can drill through the toughest 1-1/4" granite or engineered stone countertop. We recommend a template be used when drilling free-hand and a scrap piece of stone be clamped under the stone to prevent excessive chipping on the backside of the stone. The 5/8"-11 arbor fits on most drills and polishing tools in the marketplace today. Available in 1", 1-1/4", 1-3/8" and 1-1/2" sizes.

You may buy seperately our core bits adapter to use with the normal electric hand drills which take 3/8" shank.
