  • Flap wheel help

    Want to know if anybody might have an idea on how to get more life out of flap wheel disks. We have been buying them lately from Lehigh Abrasives, the blue zirconium ones for steel and are having them load up quicker than they wear down. Just lookin for some help.

    Not familiar with the Lehigh ones, but have used several different brands and have not had the issue with loading. What grit are you using? Is the a surface coating such as paint or rust proof?

    I use different grits, 36/40, 60, 120 and stainless coarse twisted steel wire. Sometime I don't seem to get the cutting I want then I go to a different grit or the steel wire.

      I use Edge lube from MSC and get alot longer life from them...

      Seems crazy to think lubing a grinding wheel would be a good idea, but after a guy that worked for me brought it to my attention I'm sold 100%

        We are using them on new structural tubing that's welded with either 5p+ or .35 mig wire. Nothing exotic at all. First grinding down to the surface with a rock, then finishing out with 80 grit.
        I will look into the lube thing. Doesn't sound reasonable but most things dont anymore in this world.

          It's the excessive heat buildup. Can you move your grinding to a slightly different area to allow the first area to cool down. With this spot you are grinsing getting so hot, it is effecting your flap disc. Just as you would while sanding on wood, the abrasive disc/belt will gum-up and wear quickly if too much heat build-up happens too quickly. I can imagine that this "Lubricant" will help in that heat build-up. But you might try the cool down method first.

            I never was impressed with the flap disc from the day they came out 1960’s or 70’s?
            Dementia is jerking my chain now days!
            I would much rather use a grinding wheel first, then start with a 36 grit sanding pad, then to 50 or 80 depending on the finish I want. I feel the flap discs are over priced for the life you get out of them.

                I looked this over and I am not convinced that its good for sanding wheels...It is or appears to be useful for metal only???????????? Or so it appears.

                  I thought the same untill I bought some for the employee...

                  Now I use it on many different things, and on flap wheels I've found through personal experience that they last a whole lot longer.

                  I'm not putting a sales pitch out there for the product, but at 3-4 dollars per wheel, give it a shot, I get almost double the life from 60 and 80 grit cheapo flap wheels.

                      We used to use a stick product from walter for drill bits. We also tried bees wax it worked ok but not as good as the walter stuff. I think it was called cool tool or something like that. Jef

                        Checkered Flag or anyone else for that matter. I thought I would give it a try so I placed an order for two tubes to see how it works out. The web site is one that doesn't post shipping charges in advance. You guessed it. To ship to me at standard UPS rates a distance of 85 miles, two tubes weigh 26 ounces, the shipping and handling was $16.04 and each tube was $15.55.

                        Just thought I would let anyone else dumb enough to go through a blank order, this is what you get. Got to love shipping and handling.

                          Leefy I’ve got to the point when a website doesn’t tell me the shipping and handling up front I move to another one that does. Couple times I paid more for shipping than the actual item.
                          Never again!

                              I'm thinking that reggie maybe doesn't believe in buying on line. Where I live I don't have any welding supply within 65 miles and I do hate to buy online specially when I get hung with extreme shipping but sometimes you got no other choice unless you want a long drive.

                              I do like the resources of the internet and all of the help on this site to direct me to products that work for someone. Being newly retired and new to tig, I am always looking for help and can depend on getting it here. I will just be very cautious about shipping charges in the future. I did email the company above to complain about the charge but I'm sure it's water over the dam.
