That is a 5 inch but the very best deal on small grinders bar none is the B&D 7750 from Walmart for 30$. Worth 10 of the HF ones and almost as good,,, maybe better considering the cost as expensive ones. Other tools I buy up, this particular one its all we use anymore.
I can say this about this tool without blowing smoke out my ***. I can see some part timers being wide eyed at the HF stuff, but they have 3 or 4 units, split the use on a Saturday morning, of course it lasts a long time, light load, low hours. If a guy would put an hour meter on one you would be surprised how low, only in professional shops do they see real use. Doubt a guy could wear one out on a car, usually isn't outright wear that kills them **** a fault combined with heat. Most operators are not strong enough to overload it and most home/diy types are timid enough they don't pick it up and bear down on it hard enough and definitely not long enough to overload it.
I stood on ladder the other day, ground about 3/4 inch weld off on a crane about 2 ft long, smooth in about 30 mins. It was getting warm, so has every other grinder in this class, if I wanted to could overload it for about a minute but this wasn't minute job, at some point a guy is only strong enough for so long.
Point is, over 30 yrs, maybe more have field tested a lot of grinders, not every one, haven't wore every one out, some broke, some damaged, nothing smarts like your new grinder being rolled over by a pipe, ha.
This grinder resembled an industrial model, it was the 2750 with paddle switch, had several, even bought 3 at once when use was hi the brushes were a weak spot. , anyway am stumbling thru Walmart, had heard these were good, picked one up and was impressed by the weight and feel, I like paddle but thought wtf, it ran nice, tossed it behind my pickup seat bought another and said, lets put this pos on the bench. I got another one there, used about 10% when we cant find this one but told my men, use this one. We use a lot of used materials working on well used machinery. Not only is it not used as a "part time" tool it is used by multiple operators.
I got some Makitas, I got some red, yellow, blue and a few black. Will trade any of them even up for this. 5 years as near as I can figure, thousands of cycles, probably sharpen brush hog blades 75 times alone which if I didn't do anything else would have made the raw tool cost about a quarter a use, but thousands, some easy but some heavy weld removal too, never overheated it, not a problem including,,,, cord, had first problem at 5 yrs with a switch and was going to toss it, my guy says, let me take a look, turns out it was repairable and the brushes still look 50%, another couple years it died again, didn't smoke, just quit, I figure its the switch, didn't look, replaced it in about 30 minutes, had someone near a store.
I usually remove broke tools, this one still here gonna play with it if I can remember. I want to drag out box of old 2750's, DeWalt 402 the chassis looks identical, I wanna take back plastic and paddle switch and stick on this cheapo.
Not all cheap tools are good but I think here was a case they copy an existing line in the industrial, they try to make it cheaper, due to technology, improvements in materials and a little design that worked in their favor the consumer version turned out way better than the original ever was minus the paddle switch feature,,,, which I am used to, not perfect but not a deal breaker.
I am almost in about a year and a half on its replacement, so far its running me about 5 dollars a year for a power tool we use daily.
Even if a branded deal for 150 would have lasted twice as long,,,, which hasn't been my experience with this particular tool, would have cost 4 times as much.
