Wagon drill with D73H drifter drill and MA3 air motor chain feed mast. I added handles on the drifter head so it can be operated independent of the wagon and mast. Includes a quantity (probably 20) of new and used carbide and tool steel bits and adapters from about 1.375" to 3.5" along with various hex drill stems and rope thread sections and adapter. 1" hex shank. I used a 175 CFM compressor. I wouldn't use smaller. Hasn't seen much use and I'm too old to provide it. It's a beast in rock.
