132961 - Miller 3/32 V-Knurled Drive Roll for Flux Core Wire

Stop Slipping and Start Welding

If you are running 3/32 inch flux-cored or metal-cored wire, you know that feeding issues can ruin your day and your welds. The Miller 132961 V-Knurled Drive Roll is the solution to common feeding headaches like wire slippage, bird-nesting, and inconsistent arc starts. Designed specifically for hard-shelled cored wires, this drive roll features a textured, knurled groove that bites into the wire just enough to push it through the gun cable smoothly, without crushing it flat.

Using the wrong drive roll is a rookie mistake that leads to frustration. Smooth V-groove rolls are great for solid wire, but they rely on pressure to grip. If you crank down the tension on a cored wire to get it to feed with a smooth roll, you risk deforming the wire into an oval shape. This increases friction in the liner and contact tip, causing drag and erratic feeding. The Miller 132961 uses teeth (knurls) to grab the wire, meaning you can run with lighter tension settings while still getting a powerful, consistent feed. This extends the life of your liner and contact tips and keeps your arc steady.

This package includes one single drive roll, sized perfectly for 3/32 inch (2.4 mm) wire. It is a genuine Miller part, so you don't have to worry about fitment issues or poor machining. It drops right into your compatible Miller wire feeder and gets you back to work immediately. Whether you are welding thick structural beams or repairing heavy machinery, reliable wire feeding is the foundation of a good weld. Don't let a worn-out or incorrect drive roll compromise your quality.

Keep your beads looking good and your downtime low. Swapping out your drive rolls when changing wire sizes or types is a quick maintenance task that pays off in smoother operation. With the Miller 132961, you get the traction you need for heavy cored wires, ensuring that every trigger pull results in a smooth, continuous feed. It is an essential upgrade for any welder tackling heavy-duty projects with 3/32" wire.
