Ring Sawing
A cutting edge sawing methodRing saws were developed as a more cost-effective alternative to chain sawing for when it comes to making corner cuts.
Ring sawing is done with a ring-shaped blade which is not limited by an arbor & collar in the center. The blade is attached to the saw at the very end by an eccentric drive. This leaves the entire blade diameter available for cutting, which allows deeper cuts using a smaller blade.
