Drawer lock joints made using a drawer lock router bit are a GREAT way to put drawers together. Once the setup is right the joint can be cut very fast, and the mechanical interlock the joint provides makes it very strong. What’s not to like? Well, in all honesty the getting the setup just right can be fussy.

MAKING THIS WORK
For a drawer lock joint to fit correctly, the height of the bit AND the fence position must both be perfect. If either one is off, you’ll have a lousy fit, which compromises the joint. Bit height is especially critical. It’s definitely very handy to have a router lift in your table for making these fine height adjustments.
