5.0 out of 5 stars Solid Grinder
This grinder has all the important features. Safety trigger, brushless motor, uses the older 18V batteries, adjustable guard, and a blade holder with a convenient lever to tighten and untighten with the hand which eliminates keeping up with that wrench. Rigdgid is reputable. Good buy for me!

First of all, I am Korean, and I would like to say to domestic buyers 1. The product seems to weigh about 3kg. Compared to the DCG405 model, it is much heavier and larger. 2. Usually grinder products have buttons on the left for right-handed people, whereas they are located in the middle, so I'm not used to it 3. The blade size is US standard, so the inner diameter is 22mm. The outer diameter is 4 inches and 5 inches, but it is unusually 4.5 inches. 4. The real thing is really beautiful This alone is worth buying. ... show more

1.0 out of 5 stars Disappointed it didn't work
Bought this for a Christmas present. My son just used it and it didn't work. It turned on but when he put it on the metal it shut off by itself. He tried it on other items, still didn't work. It also damaged the battery. My son ordered one to see if it was just a freak malfunction. It wasn't! The one he received did the exact same thing. He was able to return his and get a refund, I wasn't able to as it was a Christmas gift and he didn't use till months later. Do not buy this product. It's a waste of money and will damage your battery. It would be nice if the company would refund my money. ... show more

5.0 out of 5 stars Great if you have octane batteries.
Great for cutoffs when tearing out reinforced slabs that are going to get disposed. I cut everything for #4 to #8 rebar. Work best with the 9 amp octane battery I have 8 of them. Works ok with max batteries too since that all you can get new now.

4.0 out of 5 stars Handy little tool
I'm a scrapper and I like having a cordless for when I'm away from my shop. It will stall out on heavier material if you use too much pressure or the battery is low. They all probably do but this is my first cordless so I don't know.

5.0 out of 5 stars Great tool!
There is nothing I didn't like about this tool! I use it for cutting and grinding, sheath metal and steel pilings!
