Ideal for installing basin waste pipes through extra-thick vanities or wall assemblies, this 32 mm core drill has a 100 mm usable length for deep drilling. It can cut through a combination of thick stone and multiple layers of backer board in a single pass. It uses vacuum-brazed diamond technology for durability and has an M14 fitting for secure attachment to a high-speed angle grinder. The extended length makes it a reliable solution for professional installations where standard bits are too short.
