Rated 4.7 out of 5 by 18 reviewers.
Rated 5 out of 5 by Great value excellent performance After reviewing the options and other reviews on line I decided on the makita and am pleased I did. This is easy to handle powerful and performs well. It blows away my previous metabo which was more of a problem than a help on most jobs. Cannot go wrong here with the Makita. November 16, 2014
Rated 5 out of 5 by Best grinder I've ever owned!!! This grinder holds up and perfoms well. I use it for steel siding, valley tin, ceramic tile, cement board, patio brick, ect. ect... And there was a blade for every use in the kit to start out.I like the paddle switch as well over the switch on the side. As a remodeling contractor, I sometimes use it daily and have went through several in the last 15 years. This one is 2 yrs old now and still performs like the day I bought it. I blow the dust out of mine with the compressor at the end of the day when I cut cement board, or other dusty material to prevent over heating. When this one breaks or calls it quits, I will defenitley buy another one! September 6, 2010
Rated 4 out of 5 by Makita 4-1/2" paddle grinder The grinder works great. The problem I'm having is that I lost the flat bolts that hold the grinding disk in place. I have to go to a welding supply to buy disk that have the bolt built in for mounting. It's funny that Home Depot sells mostly grinding disk without a built-in mounting bolt. And doesn't sell replacement flat bolts for grinders. If y'all did ,I would buy a new flat bolt with your grinding disk. So I'm having to go to the Welding supply for grinding disk. They also sell a quik flat bolt set. October 14, 2014
Rated 5 out of 5 by Always in use I have this grinder in both of my work trucks. I am a carpenter and a handyman when I'm not at work. This is the one tool that does not get loaned out. I use just about every day. It is balanced, dependable, the paddle button is located perfectly, it is sized just right for extended use and for the money easily the best value of the three big tool guys out there. That's just me............. October 21, 2014
Rated 5 out of 5 by Great Product Bought this to widen the hole in our granite countertop for a replacement top mount sink. Even though the new sink was the same width and height of the one I was replacing it would not fit in the existing hole due to the bowl shape. I've never used a grinder before and I've never attempted any task like this, but this tool made it relatively straightforward to cut the countertop and successfully install the new sink. The tool is easy to assemble and looks well built. I bought a Makita after extensive research online. This tool seems really versatile and I plan to use it to cut tile instead of buying a tile saw for some upcoming kitchen and bathroom tiling projects. August 27, 2014
