Northfield Precision Instrument Corporation introduces their Model 700 air chuck. This 7in. diameter, 3-jaw air chuck has special jaws that grip a short diameter of the automotive “hub” shown to drill and chamfer the 5 holes. A special stop mounted to the chuck face has “air detect” holes for part seating confirmation. The stop is contoured and relieved to allow a chamfering tool to break the edge on the banking surface of the work piece.
