The Arrowmax AM-220026-B 6mm Bearing Trimmer is aimed at 1/32 Mini 4WD hobbyists who tune for low drag and predictable handling. It helps tidy bearing faces so hubs and axles rotate with less effort.
Use steady, controlled passes to correct uneven bearing surfaces and remove small burrs. This reduces friction and can stabilise wheel speed, making the car more dependable through a run.
Compatible with standard 6mm Mini 4WD bearings, the trimmer improves how bearings sit and spin, often translating to smoother laps and fewer surprises during races.
