Positive Depth Stop

One of the most overlooked features of a miter saw is the adjustable depth stop. This feature comes in handy when you need it and when you know how to use it. When making redundant cuts that do not penetrate the wood, engage the adjustable depth.

Flip down the stop, and adjust the socket screw by loosening the wingnut first. That allows you to adjust the cutting depth. When you are ready to make through cuts again, raise the stop. That keeps your adjustment where you want it, and you can flip the stop down to re-engage the saw stop.
