The TR420 is a multi-function lathe that allows you to perform the adjustment of the brake discs mounted on the vehicle, without having to disassemble them. In addition, it can also be used as a lathe for the reconditioning of disassembled disks and drums. It can work car disks, SUVs, 4×4 vehicles and vans. The standard version for grinding the disks is completed with a self-leveling and height-adjustable trolley, which ensures a quick and convenient positioning of the machine on the vehicle hub. It also includes 3 adapters for fixing wheel hubs with 4 or 5 bolts. Thanks to the support base provided with feet, the TR420 can be removed from the trolley and placed on any workbench and, together with specific accessories, allows the adjustment of disks and especially dismounted drums.
