Designed for bathroom plumbing, this 32 mm diamond core drill is the standard size for basin waste pipes in porcelain or stone vanities. It uses a vacuum-brazed diamond tip for a fast, chip-free cut and has an M14 thread for a direct fit on an angle grinder. The internal wax coolant allows for efficient dry drilling by reducing heat and clearing debris. This tool ensures a precise, clean hole for a professional, leak-proof installation.
