angle grinder wheels

Check to see whether the wheel has something stuck to the hub that's preventing it from seating properly. Place the wheel on a flat surface and sight for "out of flatness."

It seems extremely unlikely that a reputable company could be doing this. I use lots of CHEAP wheels from Harbor Freight, and never have problems.

First, the "big" Makita angle grinder is good quality. Second, Norton wheels are said to be good. We don't have them here (without searching), but their surface grinding wheels are good, so they know what they do.

Now to your wheel: It _sometimes_ happens, that, after some abuse, the wheel gets out of balance. You either dump it, or get it back to run smooth by using it. IMHO Makita wheels are bad. All wheels I got with my Makitas were of low quality.

Hey, you stole this from me. :)

Go to yer local welding supply shop and pick up an aluminum grinding wheel. You'll be absolutely amazed....

I have many Norton wheels. For the surface grinder. I like 'em. ERS

Norton is THE company for real, commercial-quality abrasives. At the shop we grind 99.9% aluminum and use traditional grinding wheels rarely. We have a makita 4.5" angle grinder and go through loads of norton cubic zirconia 80 grit flap wheels. We use fresh ones for rough work and used ones with most of the grit worn off to put a honed finish on pieces.

I guess I just got a bad one. It was doing this chattering, bouncing thing the first time I used it. I just went out and looked at it again. There was a little bit of grit molded over the top side of the metal center. I chipped that off, but that didn't make it ok. If I watch the edge closely as it is spinning down to stop, I can see a little bit of wobble in the plane of the wheel. Not much, but that must be the problem.

It's in the trash now.

Agreed. Norton is the leader in the grinding wheel industry.

One of our guys was grinding a die with a pneumatic disc grinder at a customer's shop. He was *aggressively* grinding between his legs (you conform to the die, not the other way around).

After the disc exploded, he had to be taken out of the plant in a wheelchair as he was so swollen as to be unable to stand up. Not sure if he wanted (more) kids or not.

Definitely not worth it.

I have numerous Norton surface grinding wheels and they run well. But I am not impress with their bench grinder wheels. I bought some 10 inchs ones from MSC and they are thicker on one side than the other and still do not run well after a lot of dressing with a diamond.

Therefore I assume that the wheels are made to differnet specs and probably by different manufacturing plants too.

I picked up one at an auction a couple weeks ago...and didnt realize at the time it has a much smaller arbor than normal. Is there an adapter to run a larger center (standard 5/8") wheel?

Forney sells adapters for them. Be sure to find out what pitch the grinder spindle is since there's more than one pitch made.

Cool. I now keep the grinder and a Weld-pak 100 in the truck. Once my customers have found out I can do quickie weld repairs on guarding and Stuff..Ive gotten enough work to pay for the welder already, as an adjunct to my normal service work. Next time I pull the welder out, Ill make enough to buy another HF autodarkening mask.

I bought the Makita at an auction for $10, from a guy who bid on it and a Milwalkee and got em both for $15..and had no use for either of them, let alone 2.

Auction fever....lol

I have had the highest regard for Norton. Never had a problem with the grinding stones.

I just recently loaded up on a lot of Norton sanding discs for the orbital sander from the local HD. Cannot seem to stop them from clogging and no luck cleaning them. Looked at the box of sanding discs and now I see they are made in Canada (nothing wrong with Canada, just not what I expected). So maybe it is just the company that bought out Norton is just using their name.

Stranger yet the local HD where I got them is about 1/4 mile from the Norton plant that I assumed was making the sanding discs. Go figure.

I think you mean 7/8", no? That's the size my grinder came with. There was a smaller version in the store at the time I bought it. Glad I got this one. Seems good to me. (Except for the problem with the one Norton wheel that I bought at the same time.)

So you buy them one at a time and each shrink wrapped? :-) Lowest quantity I get mine is 20 pcs. But our home-despot[tm]-wannabe sells them a piece. And every single is crap. There _are_ differences! The cheapos aren't even approved by or DSA (kind of welders union).

I think he is taking about the 1/4" thick discs. HD here sells them in singles, never seen them packed. Although I might be wrong. Cut-off discs are another thing altogether.

Just curious the wannabe be do you mean Bauhaus?

Chris

I also only get them in 20's at the dealer who sells good quality. Yes, I could get them in singles elsewhere, but why pay more?

Yes, for example. Also Obi, Praktiker, Hornbach and all the other Chinese crap outlets.
