YONBANG Cut Off Wheels 4-1/2 inch 52 Pack Cutting Discs with Storage Box Metal and Stainless Steel Cutting Wheel for Angle Grinders Ultra-Thin Cutting Wheels

Wow these are cheap! They cut metal. If you need the best, these aint them. If you just want some cheap cutoff wheels, this may be them. I had a deck. It was made of, what was sold to me as, treated wood. With in five years it was unsafe to walk on. In seven years it would crumble in your hand. Luckily, the 4x4 post, joist and stringers were made out of much better treated wood purchased from another vender. So I now have a deck with no decking on the joist, but I do have all those screws that held the crumbled old decking. I need them gone. I could try to unscrew all of them, but I thought Id just cut them off flush. And I did. About a thousand times. It took about 3-4 seconds per to cut them off. So about three or four hours, with wheel changes and moving from screw to screw, joist to joist and rubbing my aching back. They cut the screws well enough and I have no complaint on how well and long they cut. For the price theyre not bad. Would I have saved some time if Id bought Dewalt? Would it have cost way more? With out doubt. I have more time than money. Im willing to work more if it can reasonably save money. And thats what these do, save you money at the cost of some time and performance. Im OK with that, you may not be. They come in a closing case that reminds me of those old CD 50 pack spindles. I wonder how theyd play in my old Sony?
