Sand Blaster Gun with Boron Carbide Nozzle

hi power blaster - crank up the air!

Have a lot of cfm cause this thing requires a lot of air but it works great

The only reason that this gun didn't get 5 stars is because I had to supply my own plastic "stop washer" so that the Black Carbide Nozzle doesn't slip back into the gun cavity. Would cost another penny to include their own. I have a dual stage 60g compressor that works great with the 8mm nozzle. This thing GETS IT!

Thanks to other reviews, I knew I would have to modify this to get it to work. I found a simple hack. Remove the black boron nozzle. Cut down a piece of duct tape to the depth of the nozzle. Wrap it about 3/4 around the dia. of the black boron nozzle. Use a mallet to tap the nozzle down into the threaded plastic retainer. This will keep the nozzle wedged forward allowing media to flow behind it. I normally use 6mm pink ceramic nozzles. This 8mm black boron works a lot better, but had to boost the pressure from 100 to 120 psi. I blasted parts for 2 hours without issue using alum. oxide media. I am going to machine a part out of alum. to replace the white plastic retainer and lock the nozzle forward. The other features of the gun (e.g. compact size, and only 30 deg. separation between hoses) made it worthwhile to me to modify.

Tried out the gun as received. It did not work. The gun came with a piece of teflon rolled into a crude ring (of sorts) jammed in behind the tip and nozzle assembly. It was of no use that I could see. I found that when the gun was activated, the venturi effect pulled the nozzle backwards toward the air orifice, which then killed the venturi effect. The nozzle is a slip fit into the gun tip and there is nothing to retain it from moving backward. I searched through my hardware odds and ends and found a washer that would fit inside the gun tip 0.D. and that also had an I.D. slightly smaller than the nozzle diameter. Now, with the adjustable air orifice in the full forward position, the washer retains the ceramic nozzle insert and the gun works well. In summation, it is ridiculous that this supplier sells an item that is nonfunctional. Either there are part(s) missing, mismatched or wrong parts in the assembly or they just don't care that the gun doesn't work at all.

Item came ontime and package well. I did all my research on this and the results said it work with my sandblasting cabinet as well a replacement sandblasting gun for what came with mine. I got it and checked it before swapping it out with the original. All seemed good and it was simple plug n play.. time to try it out and nothing… no gritz was flowing at all just air… it wasnt picking up at all… so i guess it belongs to the kettle pot sandblasting equipment instead of a sandblasting cabinet… all searches were wrong..

As others have stated this is useless out of the box. But after modifications it's not bad.

After handling the product for less than a minute, I could see why it was so cheaply priced....The quality is very poor. And that is being nice about it. The threaded adapter literally fell out. Could not be tightened in any way, was to loose. Someone in QC took the day off when this was made. Don't waste your time or $.

Used as a replacement for sand blasting cabinet. Works very well but requires a massive amount of air flowing through it. It comes with an 8 mm nozzle which seemed excessive so I tried switching to a 3 mm nozzle but that actually built pressure up in the gun and instead of siphoning sand it actually blew the sand back reverse through the cabinet.

It arrived quickly and the price was good. I have seen complaints that the air jet was not centred relative to the boron nozzle - mine was fine so put it down to a bad Friday or recovering Monday.

Cheap and quickly put together. I bought it as a spare. Machining / air flow inside isn’t optimal but for a cheapie gun, you get what you pay for.

Nosel hole is to big
