The 5000-series mills are Sherline's most economical mills and would be a good starting point for any miniature machine shop. They feature a solid 10" (254mm) aluminum base, precision machined dovetailed slides with adjustable gibs, permanently lubricated spindle bearings, adjustable preload anti-backlash feed screws on the X- and Y-axes, two 1-5/8" (41mm) laser engraved aluminum handwheels, one 2-1/2" (63mm) laser engraved handwheel with thrust bearings, and many other features found only on the best commercial machines.
