I just received an order from lehighvalleyabrasives.com. I ordered a few grinding disks, wire wheels, and 2 each of all of their brand, flap disks. All of my welding gear is in storage at my side job. I've been so busy with my day job, I don't have time for side work. So, I just bought a 6" Dewalt for cutting, a 4.5" Dewalt for grinding, wire and flap, and a Dewalt straight die grinder. I needed these for doing shtuff around the house. Like I said, all my grinders are locked up.When I grab a flap disk, I don't think much about it. If I'm cutting dirty metal or bevelling, I grab a course one. If I'm sanding or smoothing, I grab a fine one.I would like to know other's opinions on grit for various uses? If you prefer conical v. flat, advantages v. disavantages? I don't particularly want to discuss brands, as that has a lot of previous discussion. And until they do me wrong, I will pretty much buy from Lehigh Valley."Where's Stick man????????" - 7A749"SHHHHHH!! I sent him over to snag that MIC-4 while tbone wasn't looking!

Reply:I think 60 grit is the best trade-off for aggressiveness vs life. The coarser grits seem to have short life. I don't really buy any finer grit ones, I use a worn one to get a finer finish. The saucer shaped ones seem to perform better but are generally harder to find and more expensive.
Reply:I buy the same stuff. I have found the 40 git works well as a coarse cut disk that leaves an acceptable finish. I only buy the conical, the flat wears too much and too quick on the outer edge. FWIW, I spend the extra buck for the nut on each one, well worth it.
Reply:I use flap discs frequently and like the angled ones since it seems the angle is more natural. I try to buy the ones that allow you to trim the back side to use more of the disc. I also use both coarse and finer grits on my sculptures. The big thing for me is to remember not to use the flap disc on freshly welded or very hot metal since that seems to glaze or burn the disc.Millermatic 252 MIGMiller Dynasty 200DX TIGMiller Spectrum 625 PlasmaAltas 12x36 Metal LatheBridgeport Milling Machinewww.psacustomcreations.com

Reply:I use the Lehigh I think they are 40 grit but I get the xl { I think } they are the thick one and they are flat but I grind a lot of rusty pipe heavy rust and they grind it off faster then grinding wheels the thick ones last pretty well even on heavy grinding
Reply:Been tempted to try those lehigh valley ceramic flap discs, but each time I use my 3M Cubitron 967A #56475 reminds me I don't need to be switching brands

Reply:Price wise I think they are a good value i don’t do a lot of finish work so grinding pipe saddles and paint $ for $ I think they are a good deal
Reply:I have been buying Klingspor 60 grit by the box of ten since the late 80s. But I have a grinder with a hard whell on it, right next to the grinder with the flap.Hit it first with the hard wheel, take away the bulk of it, then use the flap wheel for the finishing and contouring.

Reply:I went over this whole thing with a flap wheel a thirty-six grit from these guys. https://www.empireabrasives.com/flap...and-polishing/I had a lot of weld-spatter inside that thing, the #29 style 36 grit 4 1/2" Zironcium flap discs not only tore it off, but one disc did all the grinding, and then I went over everything and the flap is still good. Worn but still cutting like new. The metal feels as soft as butter now.

To hear her say Jack me off to the main lounge was too funny. Once in the sixth grade, there was an older woman a handwriting expert who asked us to write our name on a piece of paper, it was a rain day auditorium event. I signed Dick Hertz. She analyzed it and started saying "Who's Dick Hertz?" again and again, only interrupted by "what is so funny" finally a person from the school suggested it was a joke, haha, she turned red and reprimanded everyone.

Reply:This is the beeswax I use, it comes in a pellet form. I melt it down in an aluminum chafing dish in the oven at 325 degrees. It has almost no smell at all. Just support the chafing dish it gets flimsy. When I see that most of the pellets have melted about 10 minutes I shut off the oven and let it stay in there, the rest melt in about 20 minutes. If you break it apart instead of cutting it, just be careful it can actually cut your skin, with sharp broken edges just like glass, despite the fact it is a rather soft wax, weirdest thing.

Reply:Just got done watching a vid from Ron Covell and he mentions using bars of soap to lubricate the aluminum when he's sanding it. Weirdest thing I ever heard of, but if there's anyone who knows about getting a nice finish on metal.... it'd be him!Started using one of those diamond-edge all-steel cutting disks and love how they perform. The only downside is that you need to have another grinder with a flap disk mounted so you can knock off the very large burr they leave behind. Razor edge and just aching to find some flesh to sink into!Anyone pulled the trigger on one of those fancy all-steel versions with the diamonds on the face as well as the edge? I can see them being decent for carving in bevels when you're welding, but not much else. If they last a good while, they might be worth it... but I have a hard time imagining they'd last long enough to justify the cost.

Reply:Blue 60 grit. I like flat if I'm blending outside corner / tees. Conical for the everything else. Where I see a lot of folks waste a good disc is using it as a grinding wheel. I keep a griding disc on one and flap on the other grinder and wire brush on another. Grind it down pretty close with the wheel, then grab the flap and finish it. Use the wire wheel to get the smoke and dingleberries off."You can't out puke a buzzard"
