Questions & Answers

Can this be used as a cut off tool?

I'm wondering if this tool can also be used for cutting applications.
Asked by: Edmund
I have been using the grinder with a thin kerf cut off wheel for removing 1/2" concrete wedge anchor bolts and just recently cut off a tail piece of 1-1/4" sch 40 iron pipe used for stairway hand rails. I Highly recommend the 5AH battery for this tool to get max performance and decent run time.

Is it varible speed

Asked by: Chub
No. On or off. 0 or 8,500 Max. RPM (I suppose 'Max.' means the tool could slow under load, not that is can be manually controlled)

18-Volt Lithium-Ion Cordless Brushless Angle Grinder is rated 4.2 out of 5 by 71.
Rated 1 out of 5 by from Grinder sucks! I bought with the idea of cutting a metal barrel in half. I used (2) Gen5 batter... Grinder sucks! I bought with the idea of cutting a metal barrel in half. I used (2) Gen5 batteries and proper cutting blade with it as well. It literally took 4 full charges to make the cut. I then grinded down all the sharp edges and it used 1/2 the battery. It did the job but it took 3 hours including charge time to finish the job. Maybe it wasn't meant to cut and just grind but I got 3 minutes run time with it each charge. I don't write many reviews but I don't want to see someone needing a proper grinder and end up losing time on the job because of a similar experience as mine. Just buy a corded one!

I read the reviews before purchasing this tool and based on the positive reviews went down and picked one up. I used it to cut off several 1/2" anchor bolts sticking up out of a concrete floor. Overall the performance is very good and the grinder has adequate power but not as much as a corded type so it takes a little longer. The only problem I had was with the smaller 2 AH battery packs that comes in the drill kit, they are just too small and overheat almost immediately. The larger 5 AH battery pack is necessary for the grinder to operate properly and not have repeated thermal shutdowns. Bottom line, at $119 for the tool & $119 for the battery, it does the job but value is really not that great.

A week after I got my new Ridgid grinder, I needed to replace an exhaust pipe on my truck. I was excited to use this. I took 3 fully charged batteries with be. Knowing if probably go through then pretty quickly. Well batteries were not the issue. Every 3 or 4 seconds of grinding bolts, the grinder would shut down. I was not able to get anywhere with this thing. I went to the the garage. Grabbed an extension cord and my $12 HF grinder. Then I was able to get the job done. I call this thing a disappointing dud

This is perhaps the only ridgid tool I have ever been disappointed with and I own over 30, my use for it was not exactly the use intended for the tool. I wanted something I could put a circular chain saw blade on to girdle trees. Now I have done this with some of my corded tools and they do it with ease, but this tool kept overloading and stopping. It does cut metal quite well if you don't push it, and seems to grind metal, again if you don't push it.

Worked great until the cheap on/off switch broke off trying to turn it on. Contacted Customer Service earlier today for help, but since I didn't register the unit (6 months old-approx 10 uses) we will see if they will fix it or I have to swap it for another at Home Depot. All my tools are Ridgid tools but the last batch I bought from Home Depot is inferior to the set I bought 12 years ago. FYI to get the warranty you must register online, give the code off your receipt, enter all serials from products (battery, drill, charger, etc) mail them your original receipt and wait for them to verify your purchase. A hassle created to keep people from obtaining the "Lifetime" warranty.

Rated 5 out of 5 by from Great tools As for the LSA wait 2-4 weeks to register. If you register immediately after buying Home Depot has not forwarded the information from the register to registe immediately after buying Home Depot has not forwarded the information from the register to RIDGID. After purchasing five sets in multiple separate tools I found holding the receipt setting a reminder in my calendar and registering it 2 to 4 weeks after purchase every time the receipt gives all the information. Once the receipt number is entered registration online is complete in a few minutes and no need to send in all the extra paperwork
