Inexpensive, but made with aluminum housing, and works as well as a big name pro one.

This cheap little grinder puts my 150$ Brand name ones to shame! I use it for 3-4 hrs every day out of my 10 hr work days and it hasn’t given me any issues since day one. Just oil it every day. Owned it for almost a year now. Will be buying a couple more! Thank you for pricing this affordably. Quick delivery too.

I noticed the chuck becomes loose after alot of heavy grinding, but besides that. It's a great tool

Love this little guy. Well made all metal item. Good lever for speed control and comes with an air hose connector for automotive shop use. We use T fittings here at our location so we had to use our own fitting. The rest is rather simple...

I use it at a bare minimum of 2x a week at work. I'm a full time welder, and this thing comes in very handy with the right bits when you have to make your welds pretty.

The last astro die grinder lasted 300 years. I fully expect the same out of this one

I use it to sharpen my riding mower cutting blade because it's a real pain to lift the tractor up to unbolt the blade. This makes a easy to keep the blade sharp. Haven't had it long enough to talk about longevity, but it looks like a quality product.

Quit working the second time I used it, only using a 2" flap wheel. Was really unhappy since I dont use it all the time. The return window closed because I didn't use it enough .

In my toolbox I have 3 t210 as well as a 1HP dotco and a small 10 series dotco a couple of junk jet grinders (given to me by employer) and a the smaller Astro (would not recommend) as well as some 90,s and a Ingersoll rand pencil grinder. Also a dotco pencil grinder that is my favorite. I use this grinder all the time. It is not as good as a dotco by any stretch of the imagination ($500 verse $35) but a great value. Make sure to do the T series in both 90 and straight. Wish they had a T series in the smaller Astro grinder. I have been using them for 6 months and find them to be not to loud plenty of power and a big value buy. I use them for 1/4 inch carbide bits and stones. Not a fan of using it for 1/8 inch because it is to big. I do have air tool oil in my box and add a few drops every time I take out an air tool for use. I have the T series 90 as well and like it. This tool is a great value. Do note when I use the one at home I do have trouble with my little air compressor pushing enough air for it; but the same happens to any other of my grinders if I use them at home.

I bought one of these a couple months ago for our factory as a substitute for the electrical version. I got a request for 2 more a few days ago and ordered it. Less power than the electrical version but being a full fledged steel fabrication Company I'd say this can satisfy most demands.
