Abstract
An earth cutting tool can include one or more earth cutting devices. Each earth cutting device can include a plurality of inserts positioned within a body of the cutting device. The inserts can be tapered to correspond to a tapering of pockets defined in the body to facilitate insertion and attachment of the inserts to the body to avoid cracking of the body during brazing and/or heat treatment that may occur after the inserts are positioned in the pockets.
