Place your small parts (nuts, bolts, screws fitting etc) into the basket, turn on the air and set the timer and it will bead blast them like a little mini bead blasting dish washer
Perfect for restoring all kinds of production, machine shop, cool old stuff, cars, boats, planes, firearms, antiques etc
Very nicely made in PA. Requires a 2 hp air compressor and 110V.
I have a stand alone dust collector for a little more.
Have three 25 KG packages of Zirblast B40 Ceramic Media I can include for a little more as well
