Sealed ER Collets
Royal’s Ultra-Precision ER collets are available in 31 inch sizes ranging from 1/16" to 1" in diameter and 16 metric sizes ranging from 1 to 26 mm in diameter.
According to the company, ER collets are designed to mechanically seal by virtue of the rear slots terminating prior to the annular groove. This completely blocks the path of coolant flow to the front of the collet. Using a collet that is perfectly matched to the cutting tool diameter ensures full surface contact. This increases gripping force, accuracy and tool life while providing quality surface finishes and less vibration, the company says.
