265255 - Miller .035 Aluminum U-Groove Drive Roll Kit (4-Roll Set)

Smooth Aluminum Feeding Starts Here

If you have ever wrestled with a bird-nest of aluminum wire at the feeder inlet, you know that feeding soft wire requires the right tools. The Miller 265255 Drive Roll Kit is designed specifically to solve the headaches associated with MIG welding aluminum. Unlike standard knurled or V-groove rolls that can chew up soft wire, these rolls feature a smooth U-Groove that gently grips the wire without crushing it.

Why the Polished Finish Matters: Aluminum is sticky and soft. Rough drive rolls can shave off tiny flakes of metal as the wire passes through. These shavings accumulate in your gun liner and contact tip, leading to erratic feeding and frustrating arc instability. This Miller kit features a high-polish finish that eliminates those sharp edges, allowing the wire to feed cleanly and consistently. The result is a steady arc and less time spent clearing out your liner.

This kit is built for 0.035-inch wire and fits Miller 4-roll drive systems. Using a 4-roll system with these U-grooves gives you the best possible grip with the least amount of drive roll pressure, further protecting the wire from deformation. Whether you are fabricating aluminum trailers, repairing boat hulls, or working on custom automotive parts, upgrading to the correct U-groove drive rolls is the single most effective upgrade you can make for your aluminum setup.
