What else besides this router would I need to make cutouts on new interior doors for hinges. I already have the Ryobi hinge kit. Thanks for answering.

You want a MORTISING bit.

Hi there. You may want to follow the instructions found with your hinge kit. Aside from a traditional router, you may want to consider a cordless trim router. We recently launched our new MultiVolt 18V trim router- model M1808DAQ4M that can accept 18V batteries to go lighter, or our MultiVolt batteries for when you may need to go longer with your applications. Additionally, a cordless drill might be helpful to drill pilot holes and eventually screw in the hinge screws. Definitely check with your hinge kit to ensure you are following the instructions provided. Hope this helps.
