193331 - Miller VK-Groove Drive Roll for .045 to 1/16 Flux-Cored Wire

Get a Grip on Your Flux-Cored Welding

If you are running flux-cored or metal-cored wire, you know that standard drive rolls just don't cut it. Smooth V-grooves rely on friction and pressure, which often means you have to crank down the tensioner to get the wire to move. The problem? You end up crushing the wire, turning it into an oval shape that drags in the liner and gets stuck in the contact tip. The Miller 193331 VK-Groove Drive Roll is the solution to these feeding headaches. The "VK" stands for V-Knurled, meaning the groove has small teeth that grab the wire like a gear, giving you positive traction without needing to crush the wire flat.

This drive roll is built to handle the heavy stuff. It covers the most common structural wire sizes: .039, .045, .052, and 1/16 inch. Whether you are welding heavy plate in the shop or doing structural repairs in the field, this roll ensures your wire feeds smoothly and consistently. Consistent wire speed is the secret to a stable arc and a good-looking bead. If your wire is slipping, your voltage fluctuates, and you end up with spatter and burn-backs. Swapping out your old, worn-out rolls for a fresh set of Miller 193331s is one of the cheapest and most effective ways to improve your machine's performance immediately.

Installation is straightforward, but remember: with knurled rolls, less tension is more. Because the teeth do the work, you can back off the tension knob. This saves your feed motor and prevents metal shavings from clogging up your gun liner. These rolls are reversible and durable, made from hardened steel to withstand the abrasive nature of welding wire. Don't let a cheap or wrong-sized drive roll ruin your day or your weld quality.

Designed for genuine Miller wire feeders, this part fits perfectly and aligns correctly with your inlet and outlet guides. When you are pushing 1/16" flux-core all day, you need equipment that works as hard as you do. The Miller 193331 is the industry standard for reliable feeding of tubular wires. Keep a spare set in your toolbox so you aren't caught off guard when the teeth finally wear down after miles of weld.
