The D.L. Ricci Corp.
Hand Hole Grinder combines speed and ease of set-up to give
you the ultimate portable grinding tool for repairing existing
worn, abraded and leaking hand hole surfaces. The unique roller
arrangement permits 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.
