The Bosch PR011 plunge base works with PR20EVS and PR10E Colt™ palm router motor and greatly expands the router's versatility. It features smooth plunge action and spring-lock plunge control lever. The depth adjustment system includes a seven-step adjustable depth stop turret plus microfine adjustment on depth rod for fast, accurate bit depth setting. The precision centering design allows the subbase to be Afterlock around the bit, which makes it easy to keep the bit on intended outline when using jigs, templets, dovetail fixtures and similar guidance devices. The PR011 plunge accepts several different Bosch routing attachments, including the RA1126 tool-free Templet guide adapter, RA1054 deluxe router guide and PR012 dust hood.
