Infinity Tools has come out with a new system of insert tooling for router bits to make frame-and-panel doors. Called Insert-Pro cutters, these bits offer three different profiles so that you can cut multiple cope-and-stick patterns with just one router bit. Consequently, this system is more economical than having to buy three separate bits. When I tested the Insert-Pro cutters, another benefit was immediately obvious: Incorporating both the cope and stick knives on the same router bit saves setup time. These are big bits, and it would not be safe to use them in a hand-held mode, only in a router-table setup with an adjustable-speed router. I used them with a 31?4-hp router, set at approximately 13,000 rpm, and they cut superbly clean profiles without bogging down the router.

The cope-and-stick bit sells for $160, and the raised-panel bit sells for $140. Each bit includes one set of knives. Additional pattern sets of knives cost about $30.
