Description
Description: Core Drills are best suited for a drill press and are great for hollowing out the inside of stone ring shanks, as well as making large bead holes. These are diamond plated, and all hollow tube. I like this variety, because when the stone cores break off inside the bit, its no big deal. I push them out from the opposite end with a welding rod and the tube stock is cleared to keep drilling.
