The Nub Tools CNC Collet Chuck System, also known as a "Master Jaw System", is for CNC power chucks. A cost effective and efficient alternative to a standard collet chuck that eliminates the need to remove your chuck from the machine. This system provides a positive stop-dead length for repeatable part lengths when using a collet workstop. Installation is as fast and easy as installing a set of soft jaws. The ability to switch workholding with standard jaws to running collets in just minutes will skyrocket your shop's productivity. *A total runout average of .001" - .003" can be expected out of the box with a chuck in good condition and quality collets.
Be sure our jaws match your specifications below.
*T-nuts and jaw mounting bolts not included.
*Run out is measured with a 2" long pin, 1" hang out. Proper material support with long bars is crucial. Your collet jaws can be skim cut to be true to your machine for greater accuracy. Instructions provided.
