Amana's V-Groove CNC Router Bits Use a high-grade carbide-insert knife to create perfect signs and miters on your CNC machine. They are available in both 1/2-in. and 3/4-in. shanks and several cutter angles ranging from 22.5 to 80 degrees. The inserts have two cutting edges. When one side gets worn, rotate the insert for a brand new cutting edge. A secure locking screw system ensures maximum safety and cutting accuracy. We used Amana's V-Groove bit (above) in a ShopBot to carve our name in solid oak (below), and to cut a long miter on veneered plywood (top). The bit and the ShopBot performed flawlessly to produce a beautiful sign with crisp lettering with little or no tear out and a flawless mitered edge.
