Pistol Grip Needle Scaler WP WORKPAD 19 needles air needle scaler 5000bpm,exhaust front suitable for rust removal

The trigger gun system materials are too weak for the job this tool is meant to be used on. Just couple hours of work and the trigger failed. Upon opening the entire gun, I notice that the seat where the valve opens and closes was sumerge on a rubber type material that simple wore off. This gun requires a major upgrade.

Works great, I just wish my compressor could keep up!

Once I figured out how to use the three Allen set screws properly the tool worked very adequately. Tighten those Allen screws down very securely. Dont be shy. The instructions that came to the package were slim on details and could use more explanation for people unfamiliar with pneumatic tools. That was not a problem for me but could be for other people. Make sure you lube on the first use and once every day thereafter. I will say that the needles appear to be softer than the needles that come on an Ingersoll Rand. This is a good intermediate duty tool and thus far has performed as well as an Ingersoll Rand that costs $232 on Amazon. I believe this tool was based on a pneumatic hammer and I suspect that you could also use pneumatic Hammer attachments on it although I am not certain.
