I’ve found that the depth gauges on some plunge routers are tricky to read. For the kind of precision needed when routing inlay recesses, for example, I use as a depth gauge a drill bit whose diameter matches my desired depth of cut. With the router bit zeroed out on the workpiece surface, I trap the drill bit between the router’s turret and its adjustable depth rod, and then lock the rod. Remove the drill bit, and go to work, plunging with precision.
