Extend the life of your zero clearance inserts.
Drawing of putty to fill inserts

My drill press table has replaceable inserts. To get more life out of them, I use auto body filler to fill in the holes and restore a flat surface. After mixing the components according to the manufacturer's instructions, I apply it to the insert using a putty knife. Once the filler dries, I sand it smooth. I've found this also works for my table saw inserts to maintain their zero-clearance characteristic.
