A 5 6 inch(127 152 mm) clearance is recommended at the area where the grout is to be placed. The vertical form on the exit side (opposite the placing side) should be extended 2 4 inches (50 100 mm) away from the plate so that straps or other placing aids can be
A 45 degree lead angle facemill will produce a finer finish. Use inserts with a larger radius. A toroidal cutter or copy mill can often leave a better finish than other insert geometries. Unless the insert height on your face mill can be individually adjusted, a fly cutter often leaves the best surface finish.
