With the Spit Wet-X-Force diamond core bit, you drill smoothly and accurately through tough structural materials. Designed with a 65 mm diameter and a 450 mm working length, this core bit is engineered for wet drilling with water cooling in concrete, reinforced concrete, and natural stone. High-grade diamond segments ensure steady cutting performance through thick walls and slabs, making it ideal for creating neat pass-through holes for pipes, conduits, and ventilation ducts. The standard 1 1/4" connection provides a secure, rigid fit and reliable power transfer on your core drilling machine.
