Amana Tool, manufacturer of industrial carbide-tipped, solid carbide and replacement carbide cutting tools,  nnounced it has been awarded U.S. Patent 7,810,532 for its tambour router bit set.

The set is designed to help woodworkers easily create wood tambours for roll-top desks, breadboxes, kitchen storage areas and a number of other projects.

Amana’s three-piece set, designed in partnership with master craftsman Lonnie Bird, produces tambours that interlock with a ball-and-socket joint, eliminating the need for cloth, glue or wires. The first router bit shapes the face of the wood stock, requiring a cut on each face to complete the contour of the ball. The second bit creates the socket. A third bit in the set shapes the end of the tambour, which provides a place to mount a pull for opening the completed tambour.
