Review on 🪓 Oregon Grinding Wheel, 4.125 Inch x 0.1875 Inch - OR4125-316A by Eddie Fowler

A quality grinding wheel makes a world of difference to the cheaper wheels found on some smaller chain grinders. This is one of the few 1/4" thick grinding wheels available for many small chain grinders. Used primarily for adjusting the height of depth gauges ("rakers"). However, due to its width, it doesn't fit all grinders, either not the ones with the correct 7/8" bore. Some smaller grinders don't have enough threads on the shaft or enough clearance under the cover for this wheel.
