Pie Jawssuit CNC Power Chucks
Abbott Workholding, the originator of Pie Jaws®,first developed this innovative workholding solution in 1955.
Abbott Pie Jaws are designed to provide secure, accurate workholding for CNC turning applications, particularly when machining thin-walled, delicate or irregularly shaped components. Their circular, segmented design provides near-continuous gripping contact when machined to suit the workpiece, distributing clamping forces more evenly to help minimise distortion and maintain concentricity.
Available in lightweight aluminium, cast-iron and steel, Abbott Pie Jaws provide increased gripping surface area and improved workpiece support compared with conventional soft jaws. Aluminium versions also offer reduced jaw weight, making them particularly suitable for applications where weight is a consideration.
Available in a wide range of diameters, heights and mounting configurations to suit various chuck models and machining requirements.

Pie Jaws provide increased gripping contact around a workpiece, making them ideal for holding thin-walled, delicate or irregularly shaped components. Their design helps distribute clamping forces evenly, reducing distortion and improving machining accuracy.
Each material offers different benefits depending on the machining application:
- Aluminium: Lightweight and easy to machine, ideal for delicate or thin-walled components.
- Steel: Provides strength and durability for heavier-duty machining applications.
- Cast Iron: Offers excellent rigidity and vibration damping for stable, precision machining.
Yes. Pie Jaws can be machined to match the workpiece profile, providing a larger gripping surface and improved concentricity. This makes them particularly suitable for components requiring accurate, repeatable clamping.
Pie Jaws are available in a range of sizes and mounting configurations to suit various chuck models. Compatibility depends on the chuck size, serration or mounting style, bolt spacing and jaw dimensions. Always confirm compatibility before ordering.
