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.

The included angle on pointed soft jaws is 120°. Centered tongue soft jaws are available for tongue and groove lock type soft chuck jaws, These soft jaws can be machined on both sides because mounting holes are centered. Also useful for large-diameter parts because less soft jaw-material removal is required.Steel Soft Chuck Jaws are made from 1018 or 1050 steel. Aluminum soft jaws from T6061 or 7075 aluminum. 7075-T6 Aluminum is Premium, aircraft grade Aluminum and is used to make soft jaws for longer, repeated runs.

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. U S Shop Tools carries a large variety of Round Jaws in stock for chucks ranging from 4" to 24" in diameter. Round Pie jaws are available made from Aluminum, Steel and Cast Iron. Round chuck jaws made from 6061 T-6 solid bar stock in diameters up to 18" are available.

These hard jaws have ground gripping surfaces where they contact the part providing better concentricity. However, being that Hard jaws are primarily a roughing operation jaw gripping power and not concentricity is usually their main purpose.
