3 to 4 percent of tool diameter. 45-58 HRC. 2 to 3 percent of tool diameter. 60+ HRC. 1 to 2 percent of tool diameter. These feed rates assume a standard tool length. If an extended-length tool is needed because the hard-milled feature is also hard to reach, then a lighter feed rate is likely to be warranted.
