Dunham Tool precision R8 Collets are available in both inch and metric sizes. R8 Collets in round sizes are 1/16" to 7/8" in 1/32" increments, or 3mm to 22mm in 1mm increments. Our R8 Collets allow for more rapid tool changes, and provide an inexpensive and accurate tool holding method.
R8 Collets are typically used as holders for tool shanks, and are used in Dunham Tool R8 fixtures and R8 precision spindles. R8 Collets are also used in many other manufacturers' milling machines, machining centers, R8 precision spindles, and R8 Collet fixtures. Our R8 Collets are readily available, typically from stock.
