1/4 in. Angle Die Grinder-DISCONTINUED is rated 3.5 out of 5 by 16.
Rated 5 out of 5 by from It works great and has good power for the money I have about 20 hours on this die grinder and I must say that I'm very happy with it. It has done all that I ask of it and never gives me any problems. I had to return the first one I bought because after I opened the box it looked like some one drove over it with a truck. So I went back to home depot and got another one. This time the product in the box was in great shape. I installed the air chuck, oiled the tool and I put it to use. I use the tool for removing build up on mower blades and other rusty surfaces. I only use sanding wheels and wire wheels on this grinder so I can't tell you how it would work with a grinding stone. The trigger has good speed range and the tool over all is easy to control and handle. It has some weight to it which is a good thing. I bought this tool because I also have the Husky 1/2 inch impact gun (350 foot pounds) and the 3/8 impact gun. both of those guns have been in almost constant use for about 3 months now and all I do is clean and oil them at the end of the day. I think that all of the problems that people are having with this product is that they don't oil them everyday like there are supposed to. If you don't oil any air tool it will wear out or break in no time. The seals will also dry out which will make the tool leak over time. If I had to buy this tool over again I would the same goes for my 1/2 inch and 3/8 impact guns.

Rated 5 out of 5 by from Great value, but an air hog. I've only put about 12 hours on this tool, but it saved me a lot of money to be able to do the project I needed to get done. In case you're as ignorant of air tools as I was a few weeks ago, this thing is an air hog. I bought the Husky 20 gal compressor rated to deliver 4.3 cfm @ 90 psi and it can't keep up with this tool. I get about 1 minute of use at full RPM, followed by about 3 minutes of tank recovery on the compressor. If you want to be able to use this continuously without having to twiddle your thumbs for 3 out of every 4 minutes while the tank refills, you'll need a 60-80 gallon tank compressor to feed this tool. I don't have a lot of money to throw at a compressor or air tools right now so my $179 compressor and this $50 tool did what I needed to get done. It took me longer than it would have with a workhorse of a compressor, but I stayed in my budget for the project. All in all, I'm extremely pleased with this grinder, especially for the money. At $50, this is one of those tools that pays for itself in about an hour of use if it saves you from having to pay someone to knock out the project for you.

Rated 5 out of 5 by from Great tool, smooth and easy. This was a good purchase. The tool was ready to go when I got it home and accepted the disk I already had. It has been working great. The tool this replaced was 10 years old and failure was my fault. I would suggest this tool to anyone looking for good quality.

Rated 2 out of 5 by from Locked up as soon as air was hooked up After disassembly and reassembly ,it seems to be working fine though.

Rated 3 out of 5 by from Not bad for the price. Good for small jobs or homeowner Light weight, inexpensive, and good enough for minor jobs around the garage. Cant beat the price but you get what you pay for. Good for a back up or for a spare to use at the vacation cottage for quick clean up jobs on outboard motors or when removing thermostat from boat every year. Pleasantly pleased.

Rated 5 out of 5 by from Great little grinder! This is a really nice grinder, except it is a SCREAMER! must wear ear protection.

Rated 5 out of 5 by from Very useful tool 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.
