Tool Angles
As is the case with all metal cutting tools, single-lip milling cutters require the proper amout of cut-
tingedgerelieforbackrakeangleformaximumstockremovalandhighsurfacenish.Asregards
single-lip cutters, three different tools angles will have to be taken care of these angles being used
in all kinds of cutters.
Angle B applies to end relieved cutters only. Cutters having an angle of less than 20° should be
relief ground at between 25° and 30°
