optionally include features such as ribs flutes veins and or dimples for aiding in tool rotation details of a split wear ring section 30 a are shown in fig5 7 in this embodiment two of the split wear ring sections 30 a are used to form the split wear ring 30 however any other suitable member of split wear ring sections may be used such as three sections four sections etc when the split wear ring sections are assembled in the annular channel 19 they may have flat faces which abut each other as shown in the embodiment of fig5 7 alternatively the abutting faces may have other shapes such as tabs or other features which provide a contoured or interlocking connection between adjacent sections in the embodiment shown in fig7 the split wear ring 30 has a cross section with beveled corners forming angles a b c and d in accordance with one embodiment angles a and b are the same and angles c and d are the same such that the ring forms a mirror image and is symmetrical in a plane of the ring such a configuration facilitates assembly of the cutting bit 10 because when the split wear ring segments are mounted in the annular channel 19 they are automatically aligned with the opposing split wear ring segment s in one embodiment all of the angles a b c and d are the same each of the angles a.
