How a Cutter Works Understanding how cutters work can help you see why proper saw chain maintenance is so important.

1. The depth gauge rides on the wood and controls the depth at which the working corner bites in. 2. The working corner and side plate sever the wood fibers across the grain. This is the hardest part of the work. 3. The top plate cutting angle chisels out the severed wood fibers, lifting them up and out of the kerf.
