Sand Blaster Gun Kit,Sandblaster Sandblasting Gun for Sandblast Blast Cabinet with Boron Carbide Nozzle (8MM)

DID I SAY WOW!!! This is the best tool upgrade I've ever done in 40 years!!! 10 STARS!!! This thing kills it. I have a the big Harbor Freight blast cabinet, the gun that came with it was garbage, I upgraded it to a better one I thougt but it was so slow at cleaning. THIS IS MY THIRD ONE AND IT FLAT OUT ROCKS. I blast with sand, regular kiddy sand from Home Depot, this works so good my compressor has a hard time keeping up, its a 60 gallon, 5 horse, 220 volts, 2 cylinder and I have a 1/2" tube for sand pickup and its always uncovered it has so much through put. So I need to get three bags because two isn't enough! Seriously this is like going from a toy to an adult tool!!! Something that works! Only thing I wish it has was a on/off trigger, but I can install a valve and live with it . WOULD DEFINITELY RECOMMEND THIS!!!

HF blast cabinet. Modified to gravity feed. I was not getting enough performance from the gun that came with the cabinet and I wanted foot pedal control. After looking at all the reviews for other guns on Amazon They seemed to have either marginal performance or a high price. This one is inexpensive and had good reviews. I believe the 1/4" port foot pedals on Amazon do not flow enough air for blast media unless you are just etching glass. I built a foot pedal using a 3/8" ball valve. With this combination I can quickly remove rust, heavy scale, paint and even powder coat.

I just bought this, installed it in my blast cabinet and tried it out. Well nothing happened, So I pulled the gun apart and found that the air nozzle had not been through drilled when it was made. I drilled it out to the diameter of the nozzle end to that size. Once I had it drilled and back together it was a great blasting gun. I have had issues with my blasting media not being lifted up to the gun. I found that there were no issues with this unit and it flows significantly more than my previous $110 gun. I was able to reduce the pressure and had more consistent and uniform blasting patterns, no more streaky lines on the parts. This has saved me lots of time standing around waiting for my parts to cleanup. I am running a deep well blast cabinet with 80grit Al oxide and a twin piston 12cfm compressor. I will say this seems to require a good amount of air flor but less pressure. I think it would do a great job with vapor blast cabinets or even spraying masonry coatings or stucco and plaster.It has a plastic housing for the blasting nozzle which would likely be better for wet operations, but also looks like It can hold a wide variety of nozzle sizes. 4 stars because I had to fix it right away, but otherwise its 5 stars for the price.I would suggest this to a friend or other people Microsoft thinks would enjoy their operating systems.

This nozzle works well for my blasting cabinet (wet blasting). It’s not high quality but it is one of the only options for low-cost builds. It’s a high-CFM consumer, so I have to work in 5-6 second intervals using my 4.7 CFM compressor at 40 psi. The fittings are OK, but the media fitting rotates loosely. This actually helps in my smaller cabinet to get better maneuverability.

Good cheap gun. Recommend to drive a roll pin into the air jet to reduce the volume of air so compressor can keep up.

Be sure you adjust the air nozzle in or out until you get good media flow.Works well. I hope it lasts and I can find nozzles for it.

Upgraded my harbor freight blast cabinet with this gun and it’s a night and day difference

I purchased this gun because the 6 mm tip should be easier on my compressor, but I found that basic performance was not good. Upon investigation I found that the air inlet nozzle diameter was 4 mm, but many of the better performing guns have an outlet to inlet orifice diameter ratio of about 2, so the air nozzle should have been 3 mm to correspond to a 6 mm sand tip, not 4 mm. When I connected a vacuum gage, it only drew -7.5 inches of mercury, not terrible, but not great. So I filled in inlet nozzle with epoxy and drilled it out with a 1/8" drill bit (about 3 mm), and then the gun drew -14 inches of mercury vacuum and worked great. Thinking I simply received the wrong inlet nozzle in error, I contacted the seller. I was told they only have the 4 mm air inlet nozzle, and they do not offer a 3 mm. Conclusion: the gun offered with the 8 mm sand nozzle probably works great (I did not test it), but the 6 mm gun cannot handle all the air it receives at its inlet, so the gun's performance drops off dramatically. I would not advise buying it unless you you intend to modify it to improve performance.
