CH10-3J-SCEXT10 - 10-Inch 3-Jaw Chuck External Jaw Set

Expand Your Welding Positioner Capabilities

The Techniweld CH10-3J-SCEXT10 is a specialized set of external jaws designed for use with 10-inch, 3-jaw self-centering welding chucks. In precision fabrication and automated welding environments, the ability to adapt workholding equipment to varying workpiece dimensions is critical. Standard internal jaws often limit the maximum diameter a chuck can grip externally. This external jaw set addresses that limitation, allowing operators to secure significantly larger pipes, flanges, and cylindrical components onto their welding positioners or rotary tables.

Manufactured from high-grade hardened steel, these jaws are engineered to withstand the thermal and mechanical stresses typical of industrial welding applications. The precision machining of the jaw steps ensures that the self-centering mechanism of the host chuck is maintained, providing concentric clamping that is essential for consistent weld quality. Whether you are replacing worn components or upgrading your existing CH10-3J setup, these jaws offer a robust solution for heavy-duty workholding.

Installation is straightforward, designed to interface seamlessly with the scroll mechanism of standard 10-inch welding chucks. By swapping your standard jaws for these external units, you effectively transform the range of your equipment, reducing the need for multiple chuck sizes and improving overall shop efficiency. This set includes all three jaws required for a complete conversion.
