These parts are replacements for the grinding wheel clamp washers used in the Black and Decker 7900 bench grinder. If you own one of these venerable old grinders but have lost or bent one of the clamp washers, these are the parts you need to get to get it going again.
As stated in the manual, you must NEVER use regular flat washers to clamp the wheels. Use of flat washers can cause the wheels to crack or even explode in use, potentially causing a serious accident.
These washers have been custom made on a CNC lathe out of carbon steel to the original Black and Decker dimensions for true-running wheels and long life. To reduce the risk of corrosion they are plated with zinc (outer clamp washer) or black oxide (inner clamp washer) just like the originals.
They were designed to fit the Black and Decker 7900 bench grinder, but may fit other models. Refer to the drawings below to determine if they will work in your grinder.
