The actual depth-of-cut may be a little deeper or shallower than what appears on this table. Since vendors use
different manufacturing tolerances on bit dimensions, use the manufacturer’s advertised bit dimensions only as
a guide. Remember that a small amount of variation within tolerances can have a large impact on the final depth-
of-cut.
