The HYCON ring saw has a unique design and state of the art drive mechanism that will give you many hours of use and long lasting wearing parts that will ensure you low operating cost. Investing in a ring saw is investing in more work because it will cut 11-3/4” deep compared to common gas or hydraulic circular hand saws that only cut up to 5-5/8 It is also investing in higher efficiency because it will cut 11-3/4" deep resulting in less work afterward (e.g. a doorway) and less after work means job done faster and much cheaper!
