1-1/4" x 4" Stone Countertop Diamond Core Bit

ITM's stone countertop cores are vacuum brazed, which means the diamond is bonded to the steel rather than sintered into a segment — you get diamond on the face and down the side wall, so the core will plunge a hole and then open it out or correct a line without binding. They are ground for sink and faucet cutouts in granite, marble, porcelain and engineered stone, with a 2-1/2" cutting depth that clears any normal slab thickness, and a 5/8"-11 thread that runs straight onto an angle grinder. This is the 1-1/4" core: 3 diamond teeth on a 4" body, 2-1/2" of cutting depth. Dust: Dry cutting stone releases respirable crystalline silica. Run a HEPA dust extractor and the respiratory protection your silica exposure control plan calls for.
