This machine was purchased used but was in perfect working condition when it was used last about 30 years ago. It still turns on and sounds great! It has a 4000 rpm cutter head. Price includes two extra sets of carbide cutter head knives [two sets of 8 carbide cutting knives per set] and the 4 casters on that are mounted on the machine. This Uniplane has a single phase 110 volt 230 volt switched motor that has been wired for 230 volt. Copies of the Uniplane manuals are also included..
