4.5 grinder recommendation?

I might give them a try. I am still trying to figure out grit. HF does not list 80 grit and I am thinking 80 grit is what we used in MIG class but I don't really remember.

I see nothing wrong with trying HF flap wheels like California posted. At those low prices you have nothing to lose.

Personally I would stay away from other than name brand cut off wheels and traditional hard wheels though. To me it is just not worth taking the risk. JMHO

I'll 2nd that. In general I haven't been to impressed by any HF abrasives. But they are cheap enough it doesnt hurt to try. Except for the hard wheels, especially cutoff wheels. Shrapnel can hurt if those disintegrate on you. Keeping your guards in place is important.

.99 cent flaps are what they are. If you only go through 5-6 a year it's probably the way to go. An explanation of all the differences wouldn't be worth it. Technology changed a couple of years back and some of the newer to the market abrasives are far superior in cut speed and disc life. @ $3.00 ea they will cut faster, smoother and last 4 X longer than the .99 wheels. It's all about grit shape and size and how it is applied to the backing as well as the quality of each piece of grit. I hate grinding.

This is the way I feel about sand paper so I buy 3M sand paper. I gave up on cheap sand paper. I don't really have any experience on flap discs. They are pretty new to me. But I would like to get setup like MIG class.

I agree on sandpaper and buy nothing but name brand - Norton etc. The cheap stuff is frustrating, useless.

But aside from wearing out sooner what differences do people notice with premium angle grinder discs? You might persuade me to step up ...

I just found on eBay some Klingspor flap wheels so I ordered some.

Not that I know for certain of course but I’m confident you will be happy with any of the name brands.

I have been extremely happy with Klingspor. I was fortunate to buy the remaining inventory of metal working abrasives from my friends tool truck at a huge discount.


Plus he gave me all the auto body shop sample packs he had left. (Pics below)

The good thing about Harbor freight stuff is its cheap... The bad thing is you've still got the job to do but its broke or wore out. What's the solution?

I was out today and got 2 ea. of the 60 and 120 grit flap discs. I have plenty of Norton 5" 36 grit for real weld dressing, these are just in case I need to make something prettier. We'll see; they won't be a high use item here.

Their grinders at HF were 9.99 this weekend. Even if they are light duty, at this point, you'd have 8 or 9 for a lower end better quality one. My thought would be to keep them loaded with a different tool each like a brush or cutting disk.

FWIW,
The best product I have found for the price is Pearl Abrasives. Their redline disks last and last and last. Pearl Abrasive Co. Home
