Model No. 250TUM

Deluxe Tumbler Features:
  • 3-Way tumbling action

In the first action, the stones (or castings) tumble in the bottom corner of the barrel and criss-cross from side to side. In the second action, the hexagon barrel shape forces the stones to abrade and change position within the mass six times per revolution. In the third action, the slanted back of the barrel moves a portion of the stones gently up and down while rotating. This 3-way action is a CovingtonĀ® exclusive. Unit comes complete with belt guard, instructions and guarantee.
