2018-12-10 · This means that feeds must be 0.001" ipt or greater with larger diameters and speeds should be kept at 400-500 sfm for most types of materials. As the depth of cut increases the cutting speeds should be reduced to below 400 to minimize heat buildup in the chips. For shallow depths of cut, feeds can be up to 0.010" ipt for 1/2" diameter tools.
