The 6950 Twin Cutter Tool mounts on the lathe in place of the boring bar. It resurfaces both faces of a brake rotor simultaneously. Each tool holder is individually adjustable (in thousandths of an inch or millimeters) to facilitate precise depth-of-cut settings (Figure 1). 1. Measure the rotor thickness with a micrometer and determine the depth of cut necessary to machine both surfaces.

8. Wrench tighten the stud nut to secure the twin cutter, then set the lathe spindle lock to keep the spindle in position. 9. Turn the lathe on. 10. Loosen both tool holder lock knobs on the twin cutter and turn the depth-of-cut adjusting knobs until the tool bits just contact the face of the rotor. 11. Hold the outer end of each knob and turn the inner micrometer sleeve dial to zero (inch or metric). Always use the safety shield and other protective eye covering when machining a disc brake rotor.
