  • Grinding disc preference

    I would like to ask if there is a preference here for grinding discs to smooth welds. Is there a brand, grit or any certain type preferred?
    I have bought a couple from Home Depot but they seem to grind slowly and don't produce a good result. Thanks

    Why are you smoothing welds? What is the result you are seeking?

      W***er. W***er...W***er. I grind the crap out of things. I like smooth. I use W***er flap discs for smooth and W***er zip cut discs for quick cutting. I didn't post a Flap because I've got a 6" on a 5" with no guard and that's not a good work practice. 35 grit. Once your through the top layer which cuts real quick, it becomes slightly less aggressive, but also gives a finer polish. I posted the stars. Someone else's experience may be different? They do cost more, but they from my experience out perform and last the others available.

        I have 5 cheap 4-5 " grinders each with a different type of abrasive, I much prefer making making welds that do not require any grinding, to using any of them, for anything but prep for painting, or general clean-up. Most last too long to establish a "favorite",

          Northweldor the reason for grinding is I need a smooth finish to paint. It is also going in the house and I just want it to look nice. My first real project is a welding table and I wont worry about grinding those welds. Thanks for your response.

            oldguyfrom56, I appreciate your information. I have already taken the guard off my grinder, seems cumbersome and hard to work with. I have been a woodworker for many years and I never used the guard on a table saw either, seen people get hurt using a saw with a guard. I know its not kosher but I just don't like them...
