Ideal for deep drilling, this 20 mm extended-length core drill has a 100 mm usable length, perfect for creating passages for conduit and pipes through thick materials like granite countertops, insulated walls, or double-layered tile walls. It uses vacuum-brazed diamond technology for long-lasting cutting performance and has an M14 fitting for a secure connection to an angle grinder. The extended barrel length also helps with heat dissipation during dry drilling, making it a reliable solution for complex installations that require extra reach.
