Core Drill Machines by Johnson Machine Shop
Core Drill Machines by Johnson Machine are heavy duty electric core drill machines used primarily for granite core drilling, but can be used for any core drill operation. Our special diamond coring machines are constructed of heavy structural steel, and the frame is welded to insure maximum stability and rigidity. Complete water and hydraulic systems are built into the core drill machine and need only be connected to the source. Each core drilling machine is self-contained with motors and controls wired in ready to operate from customer’s fused disconnect. The core drilling operations may be controlled as desired by the operator. All electrical and hydraulics are located for operators convenience with built in controls. Variable pressure assures fast, economical, and clean operation.
