Brass Pie Jaws

Brass Pie Jaws Hold Delicate Materials Securely Without Marring or Distortion

Dillon Manufacturing presents brass pie jaws which firmly grip delicate workpieces without marring or distortion.  Maximum contact area from the full grip jaws provides a solid gripping surface which yields more friction for drive with reduced part distortion, while the brass provides a softer surface without marring or marking of the workpiece surface.  Standard parts available to 32-inches in diameter with custom designs available with special heights, diameters, and configurations, including a matching serration location which is exactly perpendicular to the slots. Ideal for components fabricated from brass, aluminum, bronze, and other softer, malleable alloys.    

Dillon full-grip chuck jaws are made in the USA with industry-leading lead-times. They are ideal for high-speed machining, as well as precision boring, tapping, drilling, and finishing across virtually all industrial markets.  In addition to brass, Dillon Full Grip Pie Jaws are available in 6061 aluminum, 1018 steel and cast iron. 

These wrap-around 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 serrated, tongue & groove serrated, Acme serrated, and square serrated designs.

Related Glossary Terms

  • alloys


    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • boring


    Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

  • chuck


    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • tapping


    Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
