The Drill Press Tri-Roller Swaging Tool is one of the most popular tools that we supply. It is used with a v-groove bearing and a chamfered housing. The precision rollers offer a consistent and repeatable mirror finish on the v-groove of the bearing. The rotary swaging process is quick and easily to do with proper instructions and world-class technical support. Please review our detailed instruction manual and instructional video for both training and process control for customer audit purposes.
