i own quite few 18v lithium ion makita tools and this grinder is one that i really appreciate. after reading other reviews, i wonder who would buy this with expectations of it performing on the same level as a corded model? i do a lot of interior steel stud framing and i use this grinder to cut the heads off of concrete anchors and to notch light gauge steel. this cordless grinder is GREAT for that and has a lot more torque than i expected. keep in mind that i understand tools and i know that having cordless convenience means some trade offs. it will stall out if i get stupid with it...but i use it for convenience and i know to take lighter cuts with it and to go slower than i would with a big corded unit. this thing is impressive and it will do a lot. i used it to sharpen lawn mower blades and it was great for that. i can also use it to cut thru chain links and small bolts and items that are away from electricity and would be difficult to run an extension cord to. it's a grat tool that can do a lot if you take your time and go slow on bigger tasks.

This is a very handy tool. Works great. I use it very often and can't really complain about it. It kind of goes through the batteries a little quicker than most of the LTX tools. Or maybe what I should say is that it requires a more charged battery. In other words once the battery is down so far it doesn't run this tool very well. But please understand that I usually am grinding off 3/4 inch stainless steel bolts or something of that nature. It's still awesome and great for just about any job.

This is a very handy tool indeed. It will consume batteries fairly quickly, so you would want the 3.0ah cells for extended use. Of course any cordless tool that is run continuously will chew battery power, so I can't say this is a negative at all. The tool itself I find very comfortable to hold and use and it is well balanced front to back when battery pack installed. Indicator lights will even tell you when a battery is running low so you can take it off and recharge before it completely depletes itself. I have only used it so far for small cutting tasks but the included grinding disc seems to power through most thinner metals at great speed. Thicker metal takes a little longer of course.

This was something that is a great tool for tile guys! So glad I was able to get this addition to my Makita stuff! JoeC

Great product, very fast shipping. I was able to purchace it on Amazon cheaper than on ebay. I find makita tools to be very reliable and have a better feel than other brands. I have been an electrician for 24yrs. And an electrical contractor for 9yrs. I love the new lithium ion tools from makita I have tried the for myself this past year and will be switching from dewalt to makita for my employees.
