Royal Products Ultra-Precision ER Collet, ER-16, Round, 13/32" Diameter
Royal Ultra-Precision ER collets are guaranteed accurate to 0.0002" TIR or better. Available from stock in both inch and metric sizes. This is very important because it enables you to select a collet that has been ground to your precise cutting tool size. Using a collet that is perfectly matched to the cutting tool diameter ensures that full surface contact is achieved, resulting in higher gripping force, better accuracy, less vibration, better surface finishes, and longer tool life.
