8 .0090 (0,23) NOTE: For cut-off inserts with a lead angle, maximum feed rate should be reduced by up to 40%. Maximum Feed Rate Values

Data above is for P and K material groups.Maximum feed rates should be adjusted by multiplying max feed rate values by following factors for shown material groups.Material Group M N SFeed Factor 0.8 1.2 0.8I.D. and Face Grooving For I.D. and face grooving applications, reduce feed rate by 20%.
