Review on 🔪 10 Pack of 4.5-Inch x 0.125-Inch x 0.875-Inch Cut Off Wheels for Precise Cutting of Ferrous and Stainless Steel by Josh Goldsmith

My 5 star rating comes with a caveat. First, the circles do their job very well. No complaints. I didn't want to cheat the wheel manufacturer. Second, the wheels will fit the Ryobi Wireless Corner Machine (Ryobi P421) but not as intended. The Ryobi angle grinder OEM wheel has a recessed center with metal discs on both sides. The OEM disc is centered on the shroud and the grinder drive shaft is protected by washers. The premium cutting wheels in this test are flat and only have a metal disc on one side. The disc is not centered in the angle grinder body. Does not rub, but closes. The absence of a metal disk on the back of the disk means that the grinding wheel rests on the drive shaft of the grinder. Over time, the drive shaft wears out. I went to a hardware store and bought a large washer with a 7/8" hole for about $1.00. I install a new washer on the shaft and then mount the wheel. It makes me happy. The shaft is protected, the wheel mounts are secure and it's a bit closer to center in the shroud. So the wheels work well and they fit the angle grinder they are recommended for. I used the wheel to cut the metal rod and it works.
