Rated 3.9 out of 5 by 8 reviewers.
Rated 4.0 out of 5.0 by This product can have an issue. This product is well worth the price. My business has many of them. One thing to watch for is that if it suddenly stops working but has a good air supply, it is almost always internal. It can be taken apart to find a small roll pin has dislodged from one of the bearing end plates. It can be reinserted and will work fine again. March 21, 2012
Rated 5.0 out of 5.0 by Powerful Die Grinder ! I highly recommend this Husky Die grinder, it has a 1/2hp motor vs cheaper units with 1/4hp. I love the adjustable speed control, great for slowing down to buff or speed up to grind. It is rated at 4cfm@90psi but under a heavy load you can easily triple that figure to around 12cfm@90psi for constant grinding. You put this die grinder on a large compressor with high flow fittings and it will sing and nearly get away from you ! June 11, 2012
Rated 5.0 out of 5.0 by I use this guy a lot Once upon a time, many years ago, I did automotive repair for a living. I have a complete set of name brand pneumatic tools such as impact wrenches, die grinders, drills, ratchet and chisel. They're all very old but still function...kind of. Every morning I check Home Depot's site for their "Special Buy of the Day" and these Husky air tools were on special so I bought one of everything. I'm not disappointed, they work great. I didn't realize what sad shape my old tools were in until I began using these Huskys. They're far more powerful, use much less air than my old ones and have a two year warranty. I am very satisfied with this purchase. July 28, 2014
Rated 5.0 out of 5.0 by Good Product This die grinder is much better than some other discount tool supply's product. This one rarely bogs down when cutting 18ga sheet metal. Will definitely buy again. April 30, 2013
Rated 1.0 out of 5.0 by disappointed in the tool all around first job i used it on was some light duty grinding and within five minutes the tool lost power and stopped working. had to move the bit by hand to get it to go. Added some air tool oil to it and made no difference. will be returning product for refund. Very disappointed in this product December 18, 2012
Rated 5.0 out of 5.0 by great value Very happy with this grinder. It has plenty of power and comfortable to hold. For the money you won't find a better deal than this. April 30, 2011
Rated 1.0 out of 5.0 by Good for light industrial, but doesnt hold up for daily use. We bought 4 of these to use at our business to grind off sharp edges off of metal. They are used only 15-20 minutes a day and are oiled daily. After the 1st month, 2 of the 4 were dead and after 6 weeks all 4 of them stopped working. Which comes out to a total of 6-10 hrs of total use before they died. Husky use to make some with a red handle for about $10.00 more and they held up 10-15X longer then these. I wouldn't recommend them. December 5, 2013
