Arrowmax crafted this 6mm Bearing Trimmer for the detailed maintenance required by 1/32 Mini 4WD racers. The tool is intended to tidy bearing faces and remove tiny imperfections that cause resistance, and the gray finish keeps it understated yet practical.
The trimmer lets you take off minimal material from bearing surfaces to improve roundness and alignment. That reduction in surface irregularity lowers friction and helps wheels turn with less drag, which is important in tight race environments.
Use the trimmer as part of a consistent service routine: check bearings after practice and before races, perform conservative trimming, and re-evaluate wheel spin to gauge results.
