There are lots of bit profiles out there beyond the 10 must-have bits. Here are a couple more you might find useful.
Round-nose bits (also called core-box bits) — Because they cut rounded grooves, they’re ideal for sign making, fluting, decorative grooves, finger-pulls, moldings, millwork and more. Typically used with plunge routers, but in a router table with fence or handheld router with an edge guide, they’ll also cut coves.
Raised-panel bits — Create the profiled edges on door and other panels. Single-cutter bits shape only one face, but two cutter bits form the front and back of a panel at the same time. These bits are among the most massive and must always be used in a table setup. They also take off lots of stock, so multiple passes are necessary.
Specialty molding bits — These are use-them-once-in-a blue-moon cutters. They’ll never see daily duty in your shop, but for a special project requiring an intricate edge, they’re well worth their price. The one shown at far right below makes a beautiful table edge.
