Small Drawer Lock Bits
This bit is ideally suited for use on material
to 1 / " thick and should be used only on a router
2
table with a fence – not free hand.
This bit can be used to create two styles of drawer lock
joint, either blind or through (see Figure 1). There are
a few considerations when selecting either blind joints
or through joints. Getting the bit set up for cutting blind
joints is a bit easier than for through joints, but blind
joints require thicker stock and the routing removes
more material.

Cutting Blind Drawer Lock Joints
1. Prepare the drawer sides, front and back. The length
of the front and back pieces should be equal to the
desired outside width of the drawer. The length of
the side pieces should be
depth of the drawer. Prepare some trial pieces of the
same thickness (length and width unimportant). The
thickness of the front and back may be different than
the thickness of the sides.

3. Using the test pieces, create an end-grain and a face-
grain cut representing the front/back and sides of the
drawer, respectively. Note that each piece is to be
routed with the fence in the same location, as shown
in Figure 3.
