Our Hand Hole Grinder combines speed and ease of set-up to give you a high performance portable grinding tool for repairing existing worn, abraded and leaking hand hole surfaces.
The unique roller arrangement enables effortless contouring of "out of round" hand holes by following the existing shape. Truing the hand hole surface repair machine to an existing hole is accomplished by turning the four adjusting screws and aligning the stone to the adjacent sealing surface. The thumb wheel Micro feed adjusts the proper depth-of-cut, so that a minimal amount of material is removed during the grinding process.
The grinding machine power originates from a quiet, lightweight pneumatic motor, with an operating spindle speed of 5200 RPM, delivering up to 2.4lb./ft. of torque.
