Tool Good grinding disks

[Ironman]

I've been on a search for aggressive grinding disks for my small grinders. For the large ones it's the pipeliner disks at P.A.
So these ones which are made in Whitby, ont are worthy of reordering for me. At least I think they are made here, but could be chinese.
These are soft and always open up fresh abrasive to the cut. They devour metal.
If you want a grinding disk that will last 20 years, don't buy this.

You had me excited for a bit, but sadly, COO = China

Not grinding wheels but Jason, Fireball Tools on YT, has been testing flap discs and flexible abrasive discs extensively for a month or two. Haven't watched any, waiting for the summary but he usually has a good approach to this sort of testing.

The shop I'm working for now buy's a lot of walter products. They're very nice, and much better than the import junk I've always used for hard discs. I don't remember the exact model/grits, but we've recently been doing a lot of re plating jobs lately using HR/CR and AR, and they've ate it up no prob. They don't last long, so I'm glad I'm not the one buying them, but they sure chew through steel very fast, exposing new grit as you're looking for, and not glazing over.

I've spent good money on flap wheels and zip wheels, and see the value there (import flap wheels have come a long way though, but I don't trust cheap cut off wheels....), but I don't use enough hard grinding discs at home to have ever justified shelling out for expensive ones. I have a lifetime supply of various makes some name brand, most import I've picked up here and there at yard sales/auctions etc, but might realistically only burn through 10-20 a year at home. The walters were noticeably better that any of the other stuff I ever used, but looking up the price guarantees they'll never find a home in my shop....When time is money though.....

Well, it works for me.

I've tried them all (mostly) over the years but always go back to Walter. Yes they cost more but last significantly longer than PAuto or Amazon stuff, they blend nicer and use better abrasives. Same with zip cuts but I recently bought 2 boxes of Klingspor zip cuts that I'm pleasantly surprised with. Made a whole lot of cuts (2pcs of 43"x43") in 3/16" sheet steel with no issues. Lasted as long as the Walter's and didn't fly apart. Good quality.
3M quick change is my go to for my die grinders. So many options for the twist on system.
Money really does talk when it comes to consumable abrasives. Cheaper does work, but typically don't last as long and don't blend as nice.

I do not like an abrasive that lasts too long, and I'll return it if it does. I do a lot of fabrication and I'm grinding 1/4 to 3/4" steel. Rarely 1 inch as I don't like to deal with it and I'm not required to. As far as cut off disks go, I bought a box full of 200 Dewalt .049 disks for .80 each last year. They do well unless the grinder is dropped on the floor.
Quick change stuff is for removing rust and paint in my world. I bought into it and ended up leaving it on the welding table for months.
Just finished a project yesterday that used 3/4 and 1/8 plate. My shop is getting empty now and I can finally get back to converting that 98%AFUE furnace to 'pane.

So today I had to go to the shitty for an appointment with my Arthritis specialist. On the way home I had steering trouble and found myself in Princess Auto parking lot. Just wanted an oil can and a couple of widgets like windshield washer fluid, and bungee straps...big sale day.
Holy crapadoodle, the prices are way higher now. We feel hard done by if we spend 200 a month on food, and I had a little handful of stuff and went out 255 bucks lighter.
I know the dollar is junk, but it was a shock. I wanted a box to put all my Vevor grinder parts and grinding wheels , 20G chuck and E25 collets, etc. that was $12 a couple months back and now is $15.

PA and Costco have policy of not letting you leave until you spend at last $100. I don't think they have ever had to use it though.

Good discs don't vibrate as much. It is noticable.
