The roller has a taper where the colet sets with 2 allen head set screws. It's a nice item to have for the price compared to others and I'm pretty sure you could make it work. Hope this helps. **Q: Can this be used to cut straight lines** A: Yes I do it all the time take the rod off and use a strait edge for a guide and it works great I love mine use it all of the time. **Q: Will these work on the thermal dynamics sl60i plasma cutters? No they are way way to small.** A: No, it can't. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by M***E on March 3, 2026* Worked good enough I had a buddy machine different length rods to cover a range of applications. Worked very nice ### ⭐⭐⭐⭐⭐ Good stuff *by N***N on January 11, 2026* Fits my arccaptain torch very well. I highly recommend for consistent cuts! ### ⭐⭐⭐⭐ Great product but.... *by N***S on January 8, 2018* This is an excellent quality product. However, it has a center boss that is rather small in diameter and it did not fit my Lotos LTP5000's torch. The ceramic nozzle on my torch (LTP5000) is about 1.040" diameter, which is slightly bigger diameter than the inside of the Mohoo's collar, which is about 0.923" diameter, so it won't go in. But my project won't wait, and the Mohoo took quite awhile to get here, so I don't have time to order a different one. I took off the circlip that holds the collar together with the wheel base, and cut off the top part of the center collar and fabricated a larger collar to press onto it so that I could fit my torch into it... which worked fine, but the cut standoff height was now way too high and there is no way to get it lower... so that meant I also had to fabricate new wheels to go onto it (smaller diameter ones) to drop the cut standoff height to around .100"...this made it work just fine, but it was a lot of work. I see a lot of people also order the Panasonic wheel assembly to go with this, as that one has a much wider center and the wheel height is adjustable for a variable standoff. I think I will just order the Panasonic too, in case I have to adjust my standoff height (it works great now, but I haven't had it long enough to know if I need a closer standoff height for thicker stuff). ## Frequently Bought Together - RIVERWELD L-TEC PT-31 JG-40 WSD-LG40 PT-31 Plasma Cutter cutting Torch Attachments Circle Roller Guide Wheel Compass - RIVERWELD SG-55 AG-60 Plasma Cutter Roller Guide Wheel Spacer Circle Compass Stand Off fit Pilot Arc Starting - RX WELD 64Pcs Plasma Cutter Torch Consumables Electrode Nozzles Cups Kit Galvanized Copper Ceramic AG-60 Consumables --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/21501354-riverweld-pt-31-plasma-cutter-torch-circle-roller-guide-wheel](https://www.desertcart.hk/products/21501354-riverweld-pt-31-plasma-cutter-torch-circle-roller-guide-wheel) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-24*
