I work for a city municipality and I'm in charge of the lawn maintenance and street department. Ive been looking at your grinders and believe it will greatly reduce the time spent sharpening our lawn mower and bush hog blades but we also have a Vermeer brush chipper that uses four stainless steal blades about half inch thick. These four blades cost 200.00 per set and they last about one month and we don't try to sharpen them because we haven't been able to use a hand held grinder with any success we only manage to burn them and make them wavy. the machine shop charges 200.00 to sharpen them so we just buy new ones every time. if your 8000 series can sharpen these stainless steal blades then we will save hundreds of dollars per year in wasted blades Ive got 10 sets of these 200.00 dollar blades that were only used one month and are now sitting on a shelf.
