🪓 Oregon Grinding Wheel, 4.125 Inch x 0.1875 Inch - OR4125-316A Review

Some smaller grinders don't have enough threads on the shaft or enough clearance under the cover for this wheel.

This stone comes with 90 degree edges. You will go through several chains and get the edge of the chain to 90 degrees before the wheel becomes almost round. I had to put mine on a grinding wheel to get it closer. After that it works great. The fact that nothing is said about it which is why I only gave it a 3. Now that it's cracked it works like a charm. So either get a shaped stone to keep your first few chains, or save an old worn one to start that stone. I found that unfortunately no one…
