Im thinking about getting the jet jat-482 angle grinder but seeing if you guys know of other good affordable 1 hp angle grinders. I use a sp air at work and like it a lot, Im thinking its .5 hp Im not sure if they make 1 hp ones tho.
Reply:
the 3 I’m looking at and open to others. The shorter aircat is 3/4 hp

Reply:Probably a lot of things because of its size and power but I run a wire wheel on the angle die grinder. I’d like a ingersoll rand also but can’t find a 1 hp One. I think the longer ones will work good for cutting. I’m worried the jet is low on rpm for that tho at 12000 rpmThe jet is 3.2 pounds and 5.3 cfm and the aircat 4.3 cfm at 1.8 pounds so it’s a lot lighter.Last edited by motolife313; 02-26-2021 at 01:01 AM.
Reply:motolife313Your pic examples are commonly called '3 inch Die Grinders . . .'There are generally two types: low rpm/high torque - and high rpm/no torque . . .Ignore hp. ratings . . . only torque at rpm is relevant . . .

Reply:This is what I have at work and I have a similar setup at home. 2 Dotco brand, 1 Snap-on, and one that is the company issue. Application is key. The yellow one in the picture is company issued and a POS but it has lasted 11ish years. It is truly a sander not a grinder.

Reply:Here’s what we’re using here. They do have good power. I’m guessing 3/4 hp
Reply:But we see all those pretty organized shops on here, and this is the best I can do. One drawer of the work boxes... they go down hill after that.

i wanna put grease in the grease fitting before using it. Has a pretty good feel to it. A touch big but I think it will run a cut off wheel real good
dang grease gun broke while using it. Got it off the Mack truck too. Definitely a thin crappy casting
Reply:Feels heavier then the 1.8 pounds advertised and then found these papers and feels little closer to this spec lol

Reply:I'd like to know how a 'non stall' motor works
Don't think I've EVER used an air grinder or any other grinder I couldn't stall...
Reply:Don't try to cram a bunch of grease in those things, it makes them sluggish and run hot, just a squirt now and then is all they need.
Reply:Wouldn't grease get sticky and keep any dirt/metal filings in it??? I only use airtool oil in my air stuff... which I don't really use that much these days anyways

I used one extensively to clean welds. I would look like a porcupine when I was done, I have had needles in my eye from it. But if you want to wire brush stuff I don't think anything can beat it. I cannot find any new ones, I looked. But the cable on the one I used was almost 1 1/4" in diameter. The cable was only about eight feet long. But you could run it all day long with a ten-inch wire wheel and it just kept going. If I see my old boss I will ask him what brand it was. Or you could get the Harbor Freight angle grinder. https://www.harborfreight.com/corded...ody-57003.htmlA friend picked one up for me when they were on sale for $69, the only thing that sucks is the swivel handle but I am sure some gorilla glue or tape would keep it from turning by accident, haha. It is a pretty hefty machine, I have not really beat on it as I would have years ago but I did put it under a heavy load and it did not even get hot. It feels rather tight too. I just didn't want to put my Milwaukee through that kind of abuse so I used the Bauer and it worked. I have a composite cup wheel I use on it too and it had no problem spinning it up.

Reply:Those Foredoms were perfect for polishing aluminum truck wheels. What a horrible job commercial polishing is.

Reply:LOL... the guys that polish the big aluminum and chrome wheels off the pull tractors have their work cut out for them. I've never really considered a heavier die grinder before... but I could definitely use more power on the zip discs. Might be worth looking into. I would think the reason for using air with a wire wheel would be so you didn't spin them so fast and end up wearing the wires, but maybe I'm missing out on the latest attire of the best dressed welders. The last grease gun I bought that I really liked came from a John Deere dealer, but they use full size cartridges so substantially bigger than what you had.250 amp Miller DialArc AC/DC StickF-225 amp Forney AC Stick230 amp Sears AC StickLincoln 180C MIGVictor Medalist 350 O/ACut 50 PlasmaLes

although even the 'name brand' is kinda a knockoff these days

Reply:First impression I didn’t think it had that much power but after using it for a minute I started to like it. Tried to bog it down and it didn’t stall or bog down much. Has good torque and is smooth. I like the trigger too, got some cheap bearing in it sounds like because I can hear them ratting and chattering, I’ll just put some nice bearings in it if it goes through the bearings in it now. And it is very quite, I’m not sure if the air flow is all the way up either. Looked half way, I’ll check with a flat head tomorrow

I had gotten a Milwaukee rechargeable cement gun from work to make the hole. It was bigger than I would normally use but the rechargeable part made it seem so sweet and I could not find a 1 1/4" SDS Plus bit, only 1 1/4" SDS Max bits. I believe it was the 1 9/16" Milwaukee rechargeable model. So anyway I start drilling I am above the drop ceiling and not wanting to take out the cross members, I use the tool above my head, which I knew was wrong but I figured I can hold this thing, WRONG thinking. This thing with a 1 1/4" bit locks in the cinder block web and does a 360 and almost knocked me to the ground. It hit me hard the only thing that kept me from getting knocked out was that I moved my head into it so there was no follow-through movement of my head, that is what knocks you out. But I remember standing there laughing at myself, haha. If someone goes to hit you and you cannot block it move your head into it, you might even sprain their wrist and you will not get knocked out, you may bleed but you will not go down.

Reply:I read nothing but good stuff about aircat
Reply:At one time( may still be) aircat was the manufacturer for mac tools. I have a few mac branded die grinders that were,are, aircat. Never an issue. Like any air tool, oil them often. I swear by the PB blaster air tool conditioner oil. What ever you get, I would go with composite construction over metal as the composite cuts vibration and they don't get as cold as the metal housing ones do.
Reply:No probs with my Aircat. Mind you it's not used in a production environment.

Reply:I tested the sp die grinder rated at I think 1/2 hp and it honestly seems to have better power then the aircat. I think Ill look into the sp next time since they seem reasonably priced also. The aircat is nice because its very quite

Reply:They all have 4.5 stars or better looks like.
Reply:Lots of people leave bad reviews when it's their own screwups. I imagine lots of people try to run them on a small compressor. Big die grinders use big amounts of air, can't change that.
Reply:I am never sure about the reviews on Amazon, they never seem reliable to me whether positive or negative. I do know that I have Aircat tools that I can think of and never had any issues with them. They are quiet and still retain good power. I have 1/2 impact that gets used daily and it must be 11 or 12 years old now along with numerous die grinders. Just my experience wiith them.Mike
