4" Onyx Magnetic Tumbler

Magnetic Tumbling is an automated polishing process that nearly eliminates the need for cyanide bombing, stripping, and thrumming. Tiny steel pins are driven at high speed by powerful rotating magnets at the base of the finishing bowl. Most finishing operations are completed in under 30 minutes. Just place your jewelry pieces, the steel pins, water, and special burnishing compound in the bowl, set the timer, and press the "ON" button. Shuts off automatically. Designed for polishing intricate details, tiny crevices, and multiple settings, but not flat surfaces.

The Onyx Mag 4 is an upgraded, more versatile design than Raytech's previous 4 inch dia. finisher, because it has programmable functions. This model has a variable speed control and the timer (up to 3 hours) has a digital readout. The rotation of the fan-cooled motor is reversible. Provided with a durable plastic bowl with cover and 250 grams of burnishing pins. As a detergent, we recommend our no. 910 Tumbling Soap Powder (see related products below).
