CMT Screw Slot Bit C/Sink 1/2" Shank

Any large panel or table top should be secured in a way that allows it to expand or contract without splitting. These screw-slot bits let you create screw slots so that panels can be held in place but are able to slide back and forth without splitting the wood or breaking the screw securing them. This bit is designed for use with screw that have a tapered or countersunk head. If your screws have a flat or washer type head, consider the 813-601-11 bit.
