Quick Summary
- Confirm your rim size range (10"–22.5" or 10"–26")
- Decide if you need lathe finishing (2-in-1 vs straightening only)
- Match machine to your shop volume
- Consider adding a polishing machine for aluminum alloy wheels
Why Repair Rims Instead of Replacing Them?
Wheel replacement costs $150–$500+ per rim. A professional hydraulic rim straightener pays for itself after just a few dozen repairs — and gives your shop a high-margin service that keeps customers coming back. Bent, warped, or curb-damaged rims are among the most common wheel issues, and most can be restored to factory spec in under 30 minutes.
Three Types of Wheel Repair Equipment
Before choosing a machine, understand the three categories of wheel service equipment:
- Hydraulic Rim Straighteners — Repair bent and warped rims using hydraulic pressure. Best for shops focused on structural wheel repair. See the Katool KT-WL69.
- 2-in-1 Rim Straightener & Lathe Combos — Combine hydraulic straightening with precision lathe surface finishing in a single unit. Ideal for shops that want to offer complete wheel restoration. Available in the KT-WL70 and KT-WL75.
- Rim Polishing Machines — Restore oxidized or scratched aluminum alloy wheels to a mirror finish. A high-value add-on service for wheel reconditioning shops. See the Katool KT-RPM80.

Frequently Asked Questions
Can these machines repair cracked rims?
No. Hydraulic rim straighteners are designed for bent and warped rims only. Cracked or structurally compromised rims should be replaced for safety reasons.
What's the difference between a rim straightener and a rim lathe?
A rim straightener uses hydraulic pressure to correct bends and warps. A rim lathe machines the surface of the wheel to remove scratches, curb damage, and surface imperfections. The KT-WL70 and KT-WL75 combine both functions in one machine.
Are these machines compatible with steel wheels?
The KT-WL69, KT-WL70, and KT-WL75 work with both alloy and steel wheels. The KT-RPM80 polishing machine is for aluminum alloy wheels only — not compatible with steel wheels.
How long does a typical rim repair take?
Most straightening jobs take 15–30 minutes. Lathe finishing adds another 15–20 minutes. The KT-RPM80 polishes a rim to mirror finish in 6 minutes.
Do these machines ship from the US?
Yes. All Katool wheel service equipment ships from our US warehouse via LTL freight carrier, with typical delivery in 6–10 business days.
What warranty is included?
