Hand Hole Grinder

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.

Tire Grinder

This precision heavy-duty grinding machine is another innovative tool from Hydratight DL Ricci designed to help eliminate excessive downtime.

The Tire Grinder provides portable grinding onsite. It is designed to regrind tires, trunnions and rollers on kilns and large vessels, and can resurface any size tire or roller, floating or fixed, while the rotary equipment is running.

Much faster than conventional grinding, our Tire Grinder offers easy set-up with a rigid scissors mount and both an X and Y feed. The belt is easily changed and is wider for greater surface exposure plus its longer length dissipates heat better for longer portable grinding machine life. The servo control is easy to operate and the Tire Grinder is powered by an electric motor.
