Fiberglass Bonded Wheels

Say what you wish about fiberglass bonded wheels. I happened on these wheels several years ago. They are actually made for stainless work. I use them on one electric grinder, flap wheel on the other ( small grinders). These wheels can be used down to the nubbins and are handy to keep a small worn one to get in tight spots. They cut steel like a Grizzly and impart a very nice finish. I back ground all the vertical welds ( 1/4") on the big door to get 100% welds. 3 wheels did the entire door project.
