Why cannot it be used as a cut-off tool (as per manufacturer's manual)?? Very disappointing, since cutting-off is the main use for cordless tools.
Asked by: Neil
Hmmm. I used it with an 1/8 inch cut off wheel with no problems.

18-Volt OCTANE Cordless Brushless 4-1/2 in. Angle Grinder (Tool Only) is rated 4.5 out of 5 by 106.

I do a lot of wood carving, and this is the only grinder I reach for when starting a job. The first thing that stands out when using this grinder is the OCTANE power. I can cut, grind or carve through anything without the loss of power as the smart batteries constantly supplies what it needs. Not only is it extremely powerful, the comfort of this in the hands is amazing. It allows for a solid grip in the tool because of the textured handle, and I don't have to worry about it slipping. It also conforms around the palm very nicely. Another awesome feature that is simple, but appreciated is how easy it is to adjust the guard. I am constantly working at different angles, so to be able to push a button and adjust the guard position in seconds is awesome for me. One other thing I really like is the the lock button, and how easy it is to use when you tighten/loosen the disk I really love this grinder, and it the only one I use now. Even carving with a King Arthur's chain wheel is awesome. Definitely give this a try!

Been doing some renovations lately and adding some new tools to the arsenal. Had heard good things about the Ridgid brand and the Lifetime Service Agreement as well. This is now the 6th Ridgid tool I have bought in the last several months and I have been impressed with all of them: build quality, features, tool performance and value proposition. This grinder and a JobMax multi-tool were part of an Octane promotion and was free with the purchase of two drivers and two batteries. Just started using the grinder, but really happy with my purchase and the knowledge that the LSA is there if needed going forward. Definitely recommend!

I'M CURRENTLY REMOVING THE PAINT FROM A LARGE DECK USING ABRASIVE PADS. MY WIFE SAID IT'S TOO BAD YOU ONLY HAVE ONE GRINDER BECAUSE I WOULD HELP YOU !!!!!!!!!! I WAS IMMEADIATELY ON MY WAY TO HOME DEPOT I HAVE BEEN WANTING TO TRY ONE OF THE NEW OCTANE TOOLS. THE 40% MORE POWER IS NO JOKE HOWEVER IT COMES AT A PRICE SHORT BATTERY LIFE! THE NEW GRINDER WILL BURN A BATTERY IN HALF THE TIME THE OLD ONE DOES ! ALSO WHEN I REMOVE THE BATTERY, IT IS TOO HOT TO CHARGE ! SO I HAVE TO WAIT FOR IT TO COOL DOWN. WHEN I BOUGHT THE NEW GRINDER I NOTICED THE FINE SCREEN ABOVE THE THE BATTERY FOR COOLING .....IT DOES'NT WORK. THIS IS NOT MY FIRST EXPERIANCE WITH RIGID I LOVE THEIR TOOLS AND MOST GUYS ENVY MY COLLECTION, BUT ON THIS THEY NEED TO GO BACK TO THE DRAWING BOARD

I have not used it for more than a few minutes per battery charge, but plenty of power for the jobs so far. I was concerned about battery power and life, but it seems comparable to a 120V unit that I've had for years. Again, convenient and does the job intended.

You don't have to keep your finger or hand in one position, on the trigger. You can adjust how your holding it for comfort. I can hear a power change as the battery gets depleted. It does stop when it needs charged. Grinding at a descent rate and no slowing down to a crawl before battery dead. Battery may last 45 min. to an hour at best, if you have to use it a bit. Overall I like it! Corded grinders are better and will remain my first choice, but there are times no cord is convenient and handy to use. Rated it Good, because there's always room for improvement. If there's no room for improvement, then it's perfect and can only go down hill from there!

Rated 5 out of 5 by from Maybe the best 18v grinder ever I needed a new grinder for a roofing job on a metal roof and used it with a knoted wire brush head. Anyone using one of these know it takes a lot of torque and a 18v cordless is probably not the right tool however I really didn't want to deal with a cord so cordless Is what I got and it absolutely works like a charm. I do recommend the octane battery if you need xtra torque you can definitely tell the difference and it will rip through material. I like the warning light which tells you if you are putting too much pressure on the tool and I never overheated the tool or battery because of this, and I found that I needed a rest before the grinder needed a rest. Now a bit about the features of the grinder. The handle can be placed in 3 locations which I found nice when using the cut off blade and the guard is easily adjustable to keep sparks off of the user. My only complaint on this tool is it doesn't have a place to store the spanner wrench. I think the guys at ridgid could look at the old ryobi grinder and find a way to store it in the handle securely.

Rated 1 out of 5 by from I give in 1 star because of the bogus warranty claim. Ridgid claims that the warranty can be done... I give in 1 star because of the bogus warranty claim. Ridgid claims that the warranty can be done online but they still require you to snail mail in an original receipt. No receipts were given with my order. I had uploaded the order confirmation/receipt online with my application. They sat on it for almost 2 months so the LSA warranty time limit submission would lapse. I argued with the customer service representative and told her that they should put on the website that the LSA can't be done online and she insisted that it can even though they are not allowed to review the updated receipt. So it really only deserves one star.
