To find the correct chuck and liner size for your cap, measure the outside diameter of your cap and then use the chart to locate the cap range that your cap falls within.  Your cap may fall within the cap range of more than one chuck. When this occurs, choose the larger chuck size for an optimal fit.

Combine strong gripping power with a high tensile strength for excellent wear characteristics. We offer white rubber liners in 55 durometer and 80 durometer. Our standard white rubber liner, 55 durometer, is an excellent choice for most applications. The 80 durometer white rubber liners are an excellent choice for highly abrasive caps.

All chucks are 3/8" square drive; drive adapters are supplied with our electric machines. 

Liner A codes - 55 Durometer

Liner B codes - 80 Durometer

Please note, deep-well chucks and machined liner-less chucks are available, please contact us for information.
