132955 - Miller 1/16 VK-Groove Drive Roll for Flux-Cored Wire

Reliable Feeding for Flux-Cored Welding

Every welder knows that a smooth, consistent wire feed is the foundation of a good weld. If your wire is slipping, stuttering, or birdnesting at the feeder, your focus shifts from the puddle to the machine, and your weld quality suffers. The Miller 1/16" V-Knurl Drive Roll (132955) is the essential upgrade you need when running flux-cored or metal-cored wires. Designed specifically for the unique properties of tubular wire, this drive roll ensures that your heavy-duty welding projects proceed without interruption.

Why V-Knurl Matters

When you are welding with solid MIG wire, a smooth V-groove roll works fine. But flux-cored wire is different—it's a hollow tube filled with powder. If you try to use a smooth roll, you often have to crank down the tension knob to get it to feed, which crushes the wire. Crushed wire creates drag in the liner and wears out contact tips instantly. This Miller V-Knurl roll solves that problem. The groove has textured teeth that grip the wire securely without needing high tension. This means the wire stays round, feeds smoothly, and you get a stable arc without the headache of constant adjustments.

Built for Miller Feeders

This genuine Miller part is designed to fit perfectly into Miller Suitcase wire feeders and other compatible industrial models. Suitcase feeders are often used in tough environments—shipyards, construction sites, and pipeline jobs—where equipment reliability is non-negotiable. By using the correct 1/16" knurled roll, you ensure that your portable feeder delivers the performance it was built for. Whether you are running self-shielded flux core on a structural beam or gas-shielded wire in the shop, this drive roll provides the traction you need.

Maintenance and Installation

Installing the 132955 is quick and easy, getting you back to welding in minutes. Because knurled rolls create positive traction, they can sometimes generate small metal shavings if the wire is dirty or the alignment is off. It is good practice to periodically check your drive roll area and blow it out with compressed air to keep the mechanism clean. Remember, this package contains one single drive roll, so be sure to check your feeder's manual to see if you need a matched pair or a specific gear-driven set configuration. Invest in genuine Miller consumables to keep your machine running at peak efficiency.
