The JET Tools MDG1 .3 HP mini die grinder has a compact housing intended for work in confined spaces and supports varied applications with a range of accessories. Its construction combines ball bearings, steel inserts in the end plates, a brass collar, a reinforced inlet for air, and a cylinder of higher-quality steel for longer service life. A roller-equipped throttle lever provides speed control, while its self-locking design helps prevent unintended motor starts. Air exits at the rear, and an integrated regulator controls the air supply.
