This continuous rim core bit is perfect for cutting through hard stones like granite and marble. It offers efficient and precise cutting, saving you time and effort.

To use this continuous rim core bit, first, make sure your drill is set to the appropriate speed for the type of stone you're cutting. Mark the area on the granite or marble where you want to make the cut. Then, start the drill and gently apply pressure to the bit. Keep the drill perpendicular to the surface for a straight cut. When using, always wear safety goggles to protect your eyes from stone chips. After each use, clean the bit with a brush to remove any stone dust. Store it in a dry place to prevent rusting. If the bit becomes dull, it's time to replace it for continued good performance.
