We all know that attaching table tops made from solid wood can be tricky. Wood expands and contracts so you must allow for movement of the top while still holding it securely to the table. There are two new types of router bits to make this job easy. They are called screw slot cutting bits and are available for either flathead or trusshead wood screws. These bits are available from CMT for $41 each with 1/2" shanks and Rockler for $21 each with 1/2" shanks. I expect to see other manufacturers selling them soon.
