Abstract
A cutting tool having cutting teeth. The cutting teeth are formed on one end of inserts that are seated in slots provided in the body of the tool with the cutting teeth projected outwardly of the slots. The inserts are produced from a resilient material that is preset in a bowed configuration with the slots having substantially straight side walls. A relief opening is provided in the bottoms of the slots and the seated inserts are forced into an open, substantially straight position with a tail section that curls into the relief opening. Flanges provided on the inserts overlap the edges of one side wall of the slots to resist lateral displacement.
