The Infinity Tools Floating Lettering Bit does just what it's name implies. The 1/4" shank of the bit follows existing sign lettering while the carbide edge creates a 1/8" x 1/8" undercut. The result is lettering that "floats" above the surface of your work piece giving you a unique accent on signage. Check out these before and after illustrations. A unique tool that creates a stunning look for your next project!
