Dillon Extruded Aluminum Pie Jaws Are Stronger, Safer Than Castings

Dillon Manufacturing’s pie jaws made from 6061 extruded aluminum are now available up to 28" in diameter and designed to be stronger than cast aluminum jaws. Because they are machined from aluminum barstock, these large-diameter, full-grip pie jaws have none of the porosity inherent with castings, so they are stronger, more reliable and safer than cast aluminum.

These pie jaws are also be made in diameters larger than the chuck, thus increasing the chuck’s capacity. Maximum contact area from the full grip jaws provides a solid gripping surface which yields more friction for drive with reduced part distortion. Custom designs are available with special heights, diameters and configurations, including a matching serration location which is exactly perpendicular to the slots.

Dillon full-grip chuck jaws are made in the U.S. with fast leading lead times, typically two weeks or less. The jaws are well suited for high-speed machining, as well as precision boring, tapping, drilling and finishing across a wide variety of industrial markets. In addition to 6061 extruded aluminum, the Dillon full-grip pie jaws are available in brass, 1018 steel and cast iron.

These wraparound-type top jaws distribute more of the gripping pressure across the workpiece, reducing part distortion. Dillon standard and custom full-grip jaws are available in 1.5 mm × 60-degree, 3.0 mm × 60-degree, 1/16 × 90-degree or 3/32 × 90-degree serrations; American standard or tongue and groove; Acme; and square serrated key-type mounting interfaces.

Dillon chuck jaw products are ISO 9000-2015 registered.
