R8 collets are one of the most common ways to securely hold a tool in a milling machine. The R8 system was introduced by Bridgeport Machine Company for use in its milling machines. It is now one of the most common ways to hold round shank tooling in a manual vertical mill regardless of origin.
Colton Industrial R8 collets are made using high grade tool steel and are hardened and polished. These collets are also extremely high precision with a best in class 5 year warranty and are yet another example of how Colton Industrial Tools is “Helping Makers Make Better.”
