The concept of using a plunge router for boring shelf-pin holes isn’t revolutionary. But, thanks to plunge models such as Trend’s T4, DeWALT and Porter-Cable, hole drilling is fair game for trim routers too. Make a shelf-pin template with holes sized to fit a guide collar bushing, and install 1/4″ upcut spiral bit in the machine. A router works as well as a drill here, and perhaps even better.
Maybe I’m just one of those guys who roots for the underdog, but I think it’s time for our trim routers to get more credit. Try these techniques with your trim router and see if you agree.
