does this have a speed adjustment?
Asked by: btrib
Says it does in the specification info... Greg says it does not. Anyone willing to verify if, in fact, this grinder has a variable speed option?

Hi Elvisman, Sorry but we cannot give an accurate battery run time for battery. There are too many variables that can change the amount of time it runs a specific tool. Thanks for your interest. Greg

How do you control the speed? Particularly for light sanding or using abrasive 6" cup brushes for log refinishing.

Hi Mac, This is for grinding only and does not have a speed control. Thanks for your interest. Greg

18-Volt OCTANE Cordless Brushless 7 in. Dual Angle Grinder (Tool Only) is rated 3.7 out of 5 by 6.

I am not in the mood to waste my time when the tool breaks i will just toss it in the trash and go buy another one. much cheaper. the tool is 10 stars and the lsa is minus 100 stars have a great day

If I said it once, I said it a million times Ridgid's octane powered line is no joke! I love the dual battery feature able to run one or two batteries for longer run time. This tool will appeal to many including but not limited to Concrete guys, General contractors, Metal Fabricators, and even Automotive detailers. Power, speed, and runtime are its strengths. Balance, grip, and design make up its beauty. The handle has a multi-positional grip giving you the ultimate control and comfort. With its variable speed and removable positional guard, it provides you with an extra layer of protection from sparks and dust. The grinder itself is a tad heavy however I consider this to be an advantage giving you more weight behind the blade, for better cutting, buffing and grinding. I would say that this 7" grinder is not to be used as a replacement to your 4" grinder, but as an addition to your tool arsenal. It is a serious tool that has tremendous power, made for medium to heavy work. Overall I recommend one in every shop, when it comes time to use it you will be glad you have it.

Doesn't matter if its concrete or metal, this grinder absolutely owns it all. The grinder takes two OCTANE batteries, but will actually run with only one installed. The OCTANE batteries send more power to this grinder when its needed, so no issues at all trying to get though the toughest materials. The one thing that I love about the Ridgid grinders is that they have bases that twist to help keep you in the perfect ergonomic position. Now I don't need to worry about twisting my wrists in awkward positions. I also love that you can attach the handle in three different positions (left, right or top of the grinder) The guard is really heavy duty metal, but its Lso very simple to rotate/adjust with the quick release button. The disc is also very simple to change out when needed. As for build, ridgid makes this grinder to hold up in any professional setting. The casing is really solid, and I love the grip that you can get because of the over molding. It's also balanced very well, even with the two batteries in the back. At the end of the day, this grinder is an absolute beast that will go toe to toe with any other grinder on the market. Great job on this Ridgid!

The grip is extra comfortable and the spark cover easily rotates with no tools necessary this is a beast with octane battery's as well You can feel the power and torque when you hit the on button, be ready or it will twist in your hand.
