Welding Tips and Tricks

On flap grinding discs for a mini grinder. The company just started to bring them in before they closed, so I don't have much experience at work with them. I found they leave a very nice finish, duh, sanded not ground. However using them around home, retired, they seem to load up and don't bite. I would hope they would last a little better since I have to buy them now. Am I doing something wrong? THX

Try grinding/sanding with the edge of the disc. Also try a courser grit.

There are flap wheels specifically for a given material, aluminum, stainless and steel, wheels for grinding, and for blending.

If your using a wheel designed for steel on aluminum you're not going to be happy with the result.

Whatever material your grinding on, find the wheel best suited for that material

What are you grinding off. If it’s paint then it will load up any grinding wheel even stones.
