Round Chuck Jaws ( also called Pie Jaws, Full Grip Jaws, Full Circle jaws) are used widely in the wheel industry and other industries where it is necessary for the workpiece to be held in place completely. Irregularly shaped parts, thin walled parts and non-cylindrical parts are common applications where round pie jaws are used. Round chuck jaws are used where increased surface gripping is necessary with minimal part marring. Round Chuck jaws are available in various pie diameters and heights. Oftentimes it is necessary to hold an oversized part in such cases oversized round jaws may be used. For example a 14" diameter part needs to be held on a 10" diameter chuck. In such a case the part may be held with a 15" diameter set of round pie jaws that have been made with the critical dimensions to fit a 10" chuck.

Collet Pads were originally used on Turret lathes - these days they can be adapted to be used on all common jaw chucks. The way it works is as follows: Replace your existing jaws with a set of special collet pad top jaws from U S Shop Tools - made specifically for your particular chuck. These special jaws are made to hold Warner Swassey style turret lathe pads. They have a screw hole bored through them so that you can easily change pads from one size to another without having to remove the jaws. Now depending on the size of your workpiece or the bar that you need to run through your machine you can purchase various sizes and shapes of collet pads. Collet pads are available with the inside bore Round - with smooth or serrated inside surface; Square - with smooth or serrated inside surface; Hex - with smooth or serrated inside surface. Emergency Pads are also available - these are very popular - because they are soft and can be bored by the machinist to the desired shape and size.
