[Integrated Door Hinge Mortise] Our door hinge installation kit is a great accessory for cutting and installing door hinges with round or square corner hinges, thanks to two removable plastic inserts. [Easy to Install and Use] The hinge router template can adjust hinge length, thickness, rounded corners vs. square corners. In addition, it has a built-in depth gauge on the side for setting the depth, and comes with a self-centering hinge drill bit to ensure the hinge screws are perfect. Angle pieces for laying out hinges of different radius are also great. Note: Only works on doors, not for door frames. [No Hammer and Chisel Required] You only need this hinge template and a router or compact router to install the door hinges. (Router Not Included) Located on the outer wall of the routing area, just use the router depth gauge to set the depth, and then cut the door hinge shape from the template area.
