Rated 4.4 out of 5 by 12 reviewers.
Rated 5 out of 5 by Good grinder to have Grinder starts slow, must be so as not to kick out overload. After that it works great. Is not super powerful, and will not replace your corded grinder, but great for the small quick jobs. Also has a locking trigger, which is a nice touch. As powerful as any of the other cordless grinders out there. November 27, 2013
Rated 4 out of 5 by a nice tool to add to the box real nice grinder here. the guard can be moved for better positioning and so cant the handle. grinds nice and has good control. August 17, 2014
Rated 4 out of 5 by Very nice for a small project. I would buy this again. Received this about two weeks ago. I have used it several times on different items. This grinder will replace my air cut off grinder. Can not see starting up the compressor when this is just a battery snapping in, away from working. It okay as far as power goes, not what you would get from a 120v grinder. I would not recommend it for a large project unless you have a good number of batteries (Goes through a freshly charged 3 amp 18v battery in about 8 to 10 minutes). The cost is fairly high. but it should wash out when you take the LSA into account. It is really to early to give a opinion on durability. I would buy this again. August 21, 2013
Rated 5 out of 5 by 18V angle grinder Run time on the 18V 3AH X-4 lithium-ion battery is quite good. The soft start is excellent. With the battery installed the balance, grip, and weight are comfortable. I only have two complaints. Ridgid neglected to include their infamous nylon tool bag..They include a bag with the corded model! I had to spend an additional $26.00 through E-replacement parts for a storage bag! Also the spanner wrench is cheaply made. The one with this grinder is stamped out of steel and not the quality like the one that comes with the corded model. This will never replace a corded grinder for serious grinding, but for the times you are not close to an outlet this grinder will not let you down. Make sure you register this tool for the LSA program! I strongly suggest you mail in the registration with a signature required and registered mail..this will give you a paper trail should warranty documentation issues occur.
