Summary: Nice but very heavy for continued hours of use. Lots of power too. But the weight is a killer for me. So I bought the Ridgid R20102 instead at 8# that's 4# less weight, yea it was almost as expensive but you can't beat life time service, especially for this kind of tool. If you need the depth of cut buy the Makita it's a great tool, otherwise...
Summary: This grinder works okay but is brutally heavy. I guess that's just the nature of the beast. Unless you have some really big stuff to grind, buy a smaller device. I'm a big strong guy, but this thing kicks my butt in about an hour.
Makita 9-inch grinder works well for Flagstone work
14 November 2012
Summary: I orginally was helping a friend work on his vacation villa in Spain. This friend rented this very same grinder and we used it for cutting stone facing material and cement blocks. A month ago, I decided to purchase this (on Amazaon.com) to help with my hobby projects of building flagstone walks/steps. Together with the Bosch diamond tipped blade, I was able to cut through 3 1/2 inch flagstone slabs in a matter of a few minutes. I thoroughly love this product.
Summary: I bought this in order to cut compound miters on brick that I was using to build a mailbox pillar to match my house. Being from Europe I was a little skeptical that a 120V tool would be powerful enough to do this, but matched with a nice Gila diamond blade I was able to do clean straight cuts with minimal breakage in a very reasonable amount of time. Overall I'm very pleased with this tool.
Summary: Lot of power in this grinder, very good at cancelling vibration, quite heavy, but then, it's a 9 inch, what can you expect. I gave it a beating even at cutting up concrete and brick, and it works like a charm. Definitely worth the money.
Summary: Bought this to cut some limestone, I cut through about a slab four foot long and three inches thick with no problems, but on the next cut the rpm's started to die and it took a long time to do the cut, I bought a new blade as I thought this might be the problem but the same thing happened, it seemed to die as soon as it went a 1/4 of a inch into the stone, my 4 inch Makita angle grinder will do as much work as this 9" inch with half the labor.
