Covington - Bead Mill

1/3hp 110V, 60Hz Motor Small Portable Size Mounted in a Heavy Gauge Powder Coated Steel Housing Grinds up to 20-1/2" Beads at a Time Dual Speed model runs at 380rpm and 250rpm Dual Speed is Not available in 220V, 50Hz The Bead Mill makes beads from 5/16" to 3/4" in diameter. The 4-1/2" x 1/2" aluminum head has a 3/8" recessed ring in the ceiling which provides a trough for the beads to follow. Milling action is achieved by rotating the chamber while the head controls the beads location. The chamber head removes quickly for easy cleaning. This machine is best suited for producing beads from hard materials such as agate, jasper, and jade. *Please note that the Bead Mill is NOT recommended for gemstone material softer than a 5 on the Mohs Scale as this machine is very aggressive. The Two Speed Bead Mill operates at 380rpm and 250rpm. The faster speed is best suited for finishing beads after an initial grind. The slower speed reduces the abrasive action and should be used when milling softer materials such as malachite, rhodochrosite, and turquoise. These materials require light head pressure and finer abrasive grit. This unit comes complete with instructions and product guarantee. Please note that there is NOT a 220V, 50Hz model available in two speed.
