Which flap discs?

Which flap discs?

What grit for removing mill scale? What grit for finishing?

Cheap ones in ten packs, or expensive singles?

What other essential wheels are liked?

I have a bunch, but having trouble removing mill scale with flap disc on 5" Bosch angle grinder. Maybe wheel is old/plugged? It also takes forever to re-shape tool steel combination wrench with 5" metal grinding disc.

You might try the 3M Bristle Discs on mill scale.

I buy 40 grit and 60 grit mostly but I have a few that are down around 120 or 150 that I keep around just in case.
I have more questions than answers

Where the heck can you get cheap flap disks?
I saw my old boss buy ten boxes (10 per box) of them at one time because he got them for $5 a box. Not sure how he came across that deal but I'd sure like to find a deal like that myself. I just paid $8 for one 40 grit disk at home depot a couple of days ago.

The last ones I bought I got from Harbor Freight. They had a good price on an assortment package. As I recall it had three different grits of flap disks and several cutoff disks all for about the price of one at Home Depot. Harbor Freight has a 25% off coupon sale running starting today also. I got the notification in an e-mail but you can get one if you just go to the Harbor Freight home page. I don't buy much at Harbor Freight but these seemed more than adequate for the task at hand.

Thanks. I saw them online a few days ago but they look like they're no where near as beefy as the one I just bought. I looked to see what they had because I was so pissed about what I had just paid at home depot. Made in chinese should not cost so much.

I ordered a ten pack of Walter flap discs from Amazon for $10 but after a two week delay, they didn't honor the price and removed all traces of the order from my shopping cart with no explanation. Go figure.

How do you like the 40 grit (diablo)? Does it leave a spray-paintable surface or does it require a finer grit to remove sanding scratches.

I haven't tried it yet. I just bought it because my previous disk is wearing thin. It should be a beast on a project that I have coming soon. I can tell you that I prefer the Dewalt hard rocks over the Diablo. The Diablos just aren't as good. And don't cut as cleanly.
That would have been a steal. Here's why they did it:

You should send them a nice little note letting them know that you're gonna report them to the FTC for false advertizing if they do not send your discs for the agreed upon price. They can't erase their internet tracks and a $50 loss will be the least of their worries at that point.

I use the Walter 40 grit flap discs. I also have some 60, 80, 120 discs. They are great and last a long time. As it gets worn down you just have to take off the orange plastic. This gives the edge back and it continues work great. There are three arrows which allow you to refresh the disc. Once the third arrow is gone and it's worn down there is essentially nothing left on the pad side. There are some great youtube videos which explain how these work to get the most life. I fell I get my monies worth and they are a great value. I bought some from harbor freight but they aren't the same as the Walters and don't last as long. Just my .02.

Is the disc you're talking about one of these?
