The Pro model upgrades the rollers to 2" diameter, adds the billet aluminum knobs, as well as the 1/2" drive shaft as standard. It consists of a 6061 aluminum block frame with two 6" long, and 2" diameter steel rollers riding on SAE 841 oil impregnated bronze bushings. We use a superior grade of steel (1144 alloy) that is much harder than what is found on most comparable products and should last almost twice as long. The drive shaft, and all the axles are integral to the roller rather than screwed into the ends. This makes it fine to drive the mill clockwise, or counter-clockwise. All the axles are 3/8", with minimal freeplay in the bushings, and the larger 1/2" shaft comes standard.

Includes hopper and base.
