Dillon Chuck Jaws’ 18” diameter boring ring is relatively lightweight and allows soft jaws to be machined precisely and grip the intended workpiece more firmly. These jaw rings are said to provide uniform pressure on all jaws, for a consistent bore.  

The boring ring is available in adjustable or chuck-diameter-specific styles, both with no-tools attachment. The jaw boring ring compensates for jaw lift, even in worn chucks, which results in better parts concentricity. Use of this device will provide a jaw surface true to the machine centerline, reduce setup times, and increase up-times for running machined parts. 

Jaw boring rings are available for 5”, 6”, 8”, 10”, 12”,15”, and 18” chucks, or in adjustable versions for 5”-8”, 6”-10”, and 8”-12” chucks. Self-centering action provides equal pressure on all jaws.
