Abstract
An interiorly located, rotating, self sharpening, replaceable digging tooth device having a removeable cap that fits over and is attached to a shank on an excavating machine, a replaceable digging tooth mounted within one end of the cap and a female socket in the cap for receiving and retaining the tooth and allowing it to rotate therein so that the tooth is self sharpening. The removeable cap is conformable to any sized shank on any excavating machine and has a front portion that is primarily solid within which the digging tooth is inserted. As a result, the digging tooth, much like a human tooth, is much better able to resist shear forces applied to it. More than one digging tooth may be provided per cap and as many caps may be provided as there are shanks on an excavating machine.
