How a Cutter Works
Understanding how cutters work can help you realize why proper
saw chain maintenance is so important.
1. The depth gauge rides on
the wood and controls the
bite of the working corner.
2. The working corner and
side plate sever the wood
fibers across the grain.
3. The top-plate cutting angle
chisels out the severed
wood fibers, lifting them up
and out of the kerf.
