Dillon full grip jaws are manufactured from 6061 extruded aluminum bar stock which eliminates the porosity inherent with castings, thus increasing their strength and reliability. Now available up to 28-inches in diameter, they can be modified to heights of 10” and widths that exceed the chuck face diameter for increased capacity.  Maximum contact area from the full grip jaws provides a solid gripping surface which yields more friction for drive with reduced part distortion. They are ideal for high-speed machining, as well as precision boring, tapping, drilling, and finishing across virtually all industrial markets. 
In addition to 6061 extruded aluminum, Dillon Full Grip Pie Jaws are available in brass, 1018 steel, and cast iron.  Custom designs available with special heights, diameters, and configurations, including a matching serration location which is exactly perpendicular to the slots.
Dillon Chuck Jaws can provide both standard and special pie jaws in 1.5mm x 60°, 3.0mm x 60°, 1/16th x 90°, and 3/32 x90° serrations, American standard and metric tongue and groove, and acme and square serrated key type mounting interfaces. 
Dillon chuck jaw products are manufactured in ISO 9000-2015 registered facilities with industry-leading lead times, typically 2 weeks or less.
