DAMO Core Bits are designed for high-speed angle grinders with a 5/8"-11 spindle. Using advanced Vacuum Brazed Technology, they offer exceptional cutting performance and can easily drill through 1-1/4" granite or engineered stone countertops. Ideal for faucet-mounting holes in countertops and vanities, they are also suitable for construction tasks requiring holes for water, gas, or electrical piping in stone, concrete, or ceramic tile.

For best results when drilling free-hand, we recommend using a template or locator and clamping a scrap piece of stone underneath to minimize chipping. Available sizes include 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/4", 1-3/8", 1-1/2", 1-3/4", 2", 2-1/2", 3", and 3-1/2".

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

Always use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, helmet, or hearing protection used for appropriate conditions will reduce personal injuries.
