Mortising a Door Latch

Dremel helps you make a perfect mortise for the faceplate of a door latch when installing door hardware. These instructions begin after you have already drilled holes in the door according to the manufacturer's instructions included with the door latch or deadbolt you are installing.

Step 1

Slide the door latch into the latch hole and trace the outline of the faceplate onto the edge of the door with a pencil. Remove the door latch.

Step 2

Outfit a Dremel rotary tool with the 650 router bit and 335 plunge router attachment. Set the depth of cut on the plunge router attachment to match the thickness of the faceplate. Test cutting depth on a scrap of wood. The depth of cut should allow the faceplate to align flush with the edge of the door.

Step 3

Using the Dremel router attachment, remove the wood between pencil lines drawn on the door's edge to create a mortise for the faceplate. Fit the latch and faceplate into the door. Use a bevel edge chisel and hammer to square the corners of the mortise if faceplate has square corners.
