Angle Grinder Usage, Attachments & Safety - Uncle Freddy's Fab Farm

Yes, I know. She should be wearing long sleeves.

When I first started messing with 4x4s and metal, I bought an angle grinder because they are so darn useful. You can cut, shape, clean, notch, prep, and finish metal with a simple angle grinder and a handful of different wheels. In fact, when I was a kid I learned how to use my dad's bench grinder and was even caught cutting wood with that old grinder. Needless to say, Dad was not pleased.

A grinder is simply an electric motor that you attach different wheels to. The motor spins at a given rpm, and the wheel does the grinding. I know guys who built their whole trail rig with just a grinder and a drill, but for this month I'll concentrate on the different types of grinders, the attachments, and safety.

I use a coarse stone wheel (right) for removing old welds or brackets since it cuts with the most ferocity. The thin cutoff wheel (center) cuts metal quickly, but these wheels can damage easily if they get caught while cutting. The flap wheel (left) consists of many small pieces of sandpaper stacked up with a soft backing, and the paper is available in different grit numbers. These are great for cleaning off paint or surface rust, removing deep gouges from the stone wheel, or deburring cut pieces of metal.
