Where SNMU inserts are used
Square milling inserts are used mainly in face milling cutters.
SNMU is a negative square milling insert. It has a countersunk hole for a clamping screw. It has a chipbreaker on both faces. It can be turned over, so both faces are used: twice the corners of a one-sided insert.
Use the insert format, size and corner configuration specified by the cutter manufacturer; check the pocket and clamping system before ordering.
