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

Grip Bigger, Weld Better

Every welder knows the frustration of trying to mount a large piece of pipe on a positioner only to find the chuck jaws won't open wide enough. That's where the Techniweld CH10-3J-SCEXT10 External Jaw Set comes in. These jaws are built to swap out with your standard jaws on a 10-inch 3-jaw chuck, flipping the steps outward so you can grab onto much larger diameter workpieces securely.

When you're running a bead on a heavy flange or a large diameter pipe, you can't afford slippage. These jaws are made from tough steel that bites in and holds on, even when the part gets hot. They are designed to work with self-centering chucks, meaning you still get that quick, single-point tightening that saves you setup time. Don't limit your shop's capacity—keep a set of these external jaws in your toolbox so you're ready for whatever job comes through the door.

This kit includes the complete set of three jaws. They are easy to install: just back your old jaws out, slide these in, and you are ready to spin. Perfect for upgrading your benchtop positioner or floor turntable to handle the big stuff without buying a whole new chuck.
