I've been grinding welds with the aluminum oxide wheels I get in a bulk pack from HF and always dread doing it. It's slow and it's a drudgery. A buddy showed me one of these wheels and it is amazing by comparison. Knocks the welds down extremely fast and runs cool - no discoloration in the metal. Is anyone else using these?

In our production shop we use Zirconia resin fiber disks. Cheap and replaceable.
A small disk lasts about 2 days and a big disk about a week. We use a 36 grit on a 7" disk to knock down a 2" weld and then a 50grit on a 4.5" disk to give it the final finish before an 80grit DA. I find that this is the best and fastest way to grind down a weld with minimum heat absorption to the panel. For my house I have a cutoff wheel and then a 60grit flap disk which I should change to a 36 grit. I find the flap disks to be the most universal for grinding/finishing as they are very forgiving and great for when im one handed upside down or whatnot. I typically go through one a year. |
