Expanding 5C Collets

Insert expanding collet in spindle and adjust collet closer (like any 5C Collet) until expansion of mandrel is about .005" when collet closing mechanism is in activated position.
Operate collet closer approx. 25 times to break-in expanding collet for better performance and concentricity.
In expanded position, machine the mandrel .001" or .002" larger than maximum part size.
Expansion of .010" can be obtained but for best results and concentricity, expansion should not exceed .005".
