#250 A2-5 Work Locating Stop
The Sure-Grip Expanding Collet has true part length control built into its design. The workpiece locates against the face of the arbor or the face of the work stop to ensure no longitudinal end movement. All expanding collets (except the Model #100) take a machineable work stop that bolts directly to the expanding collet arbor or the machine's spindle, ensuring no end movement of the workpiece. The #400 and #500 5C-style Work Stops are bolted to an optional threaded or taper-nose spindle mount. The work stop is machined by the customer to the location requirements of the workpiece.
