Ths makita grinder was used in concrete work, the signs are there. This tool works perfect. No internal flaws but does have cosmetic wear. The grinder is missing the flange nut and gaurd but I plan to get the flange nut soon if not sold yet. I will leave the price as is without the flange nut. But will raise the price just a bit if I provide 1 as they are not that hard to get a hold of.
