Diamond Core Drill, 1800W 4'/110 mm, 1700RPM Variable Speed Core Drill Rig

4 inch Max Drilling Diameter: 1880W powerful motor of the handheld core drill rig is designed for wet drilling in reinforced concrete, stone, asphalt, marble, ceramic, walls, floors, and more. With a 4"/110mm max drilling diameter and 1700RPM stepless speed, you can drill with less effort.
Durable Steel Output Shaft & Copper Inlet: As the machine will work upside down, water will unavoidably flow on to the drill machine. In this case, our drilling rig has a rustproof steel forged output shaft and waterproof copper water inlet for a long-lasting water supply.
Over-current Protection: We also provide an overload protection system and an upgraded cooling system. They are designed for avoiding burn-in and prolonging the service lifespan of the drilling press machine.
Comfortable Shoulder Rest & Handle: The upgraded shoulder rest is designed to save your energy. The slip-proof rubber handle greatly enhances friction and reduces vibration to completely control the hammer with comfort. Besid
