The UNASIS Drill Press Cutter Tool is used to cut the v-groove of a bearing, v-groove of a housing, or the retention sleeve. Throughout the process a cut is made on the lip to ensure it is able to be pressed out without harming damaging the housing. The UNASIS drill press cutting tool is manufactured with the outside diameter of the teeth smaller than the housing bore. This is so that it is impossible to cut the housing during the operation. Please review the UNASIS instruction manual, training video, and process control for customer audit purposes.
