Ring Sawing
The ring saw has been developed from the grinder, but is powered by hydraulics and is in daily use in our industry. As with the chain saw it is hand held and rather cumbersome, although in the hands of a skilled operative it is very effective. Water supply is needed at all times. It is fairly quiet and vibration free, and the blades are diamond type. This unit can be used to form door and window openings in walls also openings in precast floors.
