Corner Radius Configuration

CNMG and WNMG wiper inserts create a true corner radius on the workpiece, just as a standard insert does.

DNMG and TNMG wiper inserts do not provide an exact corner radius on the workpiece. The radius produced falls within a ±.0025" (0,06 mm) tolerance band. (blue lines)
