NOTE: YRC = distance from centre line to the crown of the R radius. RCN = distance from centre line to the start of the cutting edge. This dimension can also help determine the minimum circle size when helical ramping. R = the head radius size. R� = the shoulder radius or radius at the corner of the cutter.
