Features: This tumbler is for a new 5-kilo rotary tumbler, jewelry polisher & finisher, super finishing, and it will be a great hobby for beginners and great tool for experts. This equipment utilizes iron beads or steel balls to work on the surface of workpiece. This machine can not only improve the specification precision of the workpiece and geometrical shapes of the workpiece, but also it can make the surface of workpiece smooth and gloss. Sometimes it is used to eliminate the gloss (extinction). Bidirectional rotation can be timed, optional five-speed. Excellent for studio and small jewelry projects. The time of processing is longer than vibratory finishing, but a distinct advantage is that the surface of work pieces get work hardened. The barrel, made of tough polycarbonate, is multi sided and will not corrode or rust, used with all types of media including steel shot.
