Grinder wheel for handheld grinders

[paul2112]

Ok fig I'd post it here. Started the rebuild of my seadoo trailer and have a lot of old welds I need to grind down, and don't want to spend countless hrs on it. What's a good grinder wheel for handheld grinders to make short wrk of it. Thanks

cut it closer then grind. and any grinder thats huge would make short work on that, say a 9" grinder.

I'd probably try to cut more material off before grinding it. Use a cut-off wheel or sawzal.
After that get a 40 grit flap wheel to remove and finish the rest and you should be good to go.

Yea, I was going to try and get a little closer with the plasma,,,,still learning to is it...So just the regular grinder wheels? But bigger than 4-1/2 ? Ok thanks guys

Use a 4 1/2, I don't even own a big one anymore. Mine died and never got replaced. Its rare but on occasion we got a jonb like that, ground a couple welds last winter and it took an extra wheel and 5 more minutes.

I do a lot of cutting in my garage.

I'd use a thin cut off wheel, 5 or 6" to remove as much as you can. Yes on a 4.5" grinder. (I'm not a fan of a 7" or 9" grinder, I've both)
then add a sanding wheel to your grinder, 36-60 grit. For me they work better than a flap wheel. But if money is no object, I use flap wheels.

I use SAIT A24N to remove a lot of material. http://www.unitedabrasives.com/ProdDescr/grdag.htm

Skip "long lasting" grinding wheels, they take forever to do anything.

I'm with the other guys, take another pass with that plasma before you start grinding. Also to SAIT wheels are great and you can buy them by the box on Amazon.

The subject of wheels comes up on occasion and here is my take. They all work pretty good with the least being the flea mkt ones at a dollar and they aint all that bad.

I bought 10 pack at TSC for 10$, not all bad and now was low and picked up DeWalt from there for a couple a piece and they are fair. The main place a good wheel performs better on a 4 1/2 is very heavy grinding like in the pic, you can notice a little life difference but its pretty much wtf, wear out another 2 $ wheel and the rest of the time you will never notice it.
I do have a sander but you can blend with a grinder to make it only noticed if you know its there and look.

^^ this. The McMaster grinding wheels work great, but there's not a huge difference between those and imports. Also, note that 9" grinders like to kick really hard, and they tend to be at a sensitive height when they do. No loose clothing and arms braced to save your future kids from impact...

+1 for the sanding wheels on a 4.5" grinder. Like others, I also have a big grinder, but only use it for really big jobs.

go to a welding supply store they usually have good quality flap discs there.

From what I have seen, they have about the best prices on the grinding wheels. Sometimes you can get a better deal on an ebay auction if you are willing to go through the hassle to save a buck or two.

I like the Sait disks. They are priced lower than the Dewalt ones I used to get from Lowes, but are just as good.

For flap disc's, I order from Lehigh Valley. Long lasting, great quality, great pricing.
