Rick’s Tip
The AV-56 stump bit grinder uses electro-plated diamond grinding wheels to sharpen the carbide bits. Where as sharpening carbide tipped saw blades you use bonded diamond grinding wheels. This means that the stump grinding wheels have exposed diamond particles coating the wheels. There are a couple things you can do to maximize the life expectancy of plated grinding wheels.
Always use light sharpening pressure when using plated wheels. This will allow the diamond particles to do the sharpening. Using too much grinding pressure will not make the bits sharpen any faster.
Because plated grinding wheels do not have any bonding agents, it is important to keep these wheels clean. A new plated wheel will have a nice grey color to them. After excessive use, the color may turn more charcoal. To clean plated wheels, soak them in acetone or any cleaner/degreaser solution and use an air hose to blow out any debris.
