This is one of my favorite tools in the drawer, enough so that I just ordered a second one. I’ve had my old GV5000 for almost 20 years and it hasn’t missed a beat. I use it extensively for metal work, it’s a little finer than an angle grinder but does a great job cleaning up edges. When I worked at a marina I used it for fiberglass work. The $79 price isn’t spectacular, but it’s been ranging for $89 for a while now. Home Depot stopped carrying it in the stores recently, so I figured I should buy a spare.
