• The standard is f=.002", corner R.008" and f=.004" for corner R.016" • For centric boring bar types, the stability limits vary based on the tool’s protrusion length; please refer to the recommended cutting conditions table for round tool types on pg. 531, and adjust the settings accordingly • If tool life is reduced due to interrupted cutting, we recommend low speed conditions or dry cutting
