<human>:  How do I use a router bit on a plunge router?
<bot>: To use a router bit on a plunge router, start by making sure the bit is properly positioned in the router's collet. After that, adjust the plunge router's depth setting as desired. Next, turn on the plunge router and press it firmly against the workpiece. Lock the router into the workpiece by pressing the plunging lever and guiding the bit through the wood until it reaches the desired depth. Finally, turn off the plunge router and remove any material from the cutting edge of the router bit before proceeding with your project.
