I have for sale a good used Atlas Copco pneumatic screw driver. Model # LUM11PRO077SS. This driver operates by pushing the bit into the fastener and then the motor engages. The button is for reverse rotation. This is a used tool and has wear, but there is s alot of working life left in it. The tool will need the proper nose bushing and extension for your specific use. I am always willing to entertain an offer. Thanks for looking.
