One of the strongest names in power tools brings this brawny grinder that boaters are apt to use when doing rugged repairs to fiberglass or trailer parts. Strong enough to cut steel or sharpen a mower blade, it can be used with a rubber sanding disk to grind rust from a trailer and prep it for repainting. Its 7.5-amp motor turns 10,000 rpm, making it too aggressive for finish sanding but great at removing excess material quickly. $57.69; acehardwareoutlet.com
