          Is the arbor threaded? (Do I need to use threaded or unthreaded disks?)
          ByAug 14, 2025
          2 Answers | 
          Answer This Question

          The grinder accepts wheels that have a 7/8" arbor hole. The wheel is held in place with a nut that is provided with the grinder. Alternatively, you can remove the nut and mount things like a wire brush that have 5/8-11 threads.

                Answer This Question

                Hello, Lisa - Use ONLY Type 27 depressed center grinding wheels. Never attach a Type 1 straight or cut-off wheel to this angle grinder. Use of any other wheel is not recommended and creates a hazard, which will result in serious injury. If you need further support, then feel free to ask another question.

                    This is an excellent grinder that exceeded my expectations. I initially used a cordless one, but the batteries were not lasting. My “Tool Buddies” recommended I use a corded angle grinder vs cordless one because the project involved grinding concrete. I did not want to spend a lot of money so I decided to purchase this one due its cost and the positive reviews from past customers. The other reason why I purchased it was the Lifetime Service Agreement through Ridgid. This is A+ in my opinion.

                    Guard lock failed on two units
                    First grinder guard lock popped off after a 1 hour of 1st time use. The 2nd grinder guard lock arrived without a spring so the lock fell off before the first use. The box was beat up and not enclosed in a mailing box like the first. Looked like a return. The on/off switch was difficult to move on the first grinder. Okay on the second. I will exchange one last time though my project is delayed by the guard lock defect. Nice grinder when it works. HD customer service consistently outstanding.

                      Corded is GREAT again
                      Ridgid 4 ½ inch Corded Angle Grinder After purchasing a large number of the battery powered grinders, I have found those tools to be of great value when working in the field. That being said when working in or around the shop the use of a corded tool is preferred. This Ridgid 4 1/2-inch grinder gives you all of the power and versatility you need. The corded tool still does the job and if that's what you began with it actually gives you the reliability you want. The improvements in the tools design learned over time are all included. The self-locking button, to change cutting, grinding, or wire brushing attachments is easy to use. Basically, you'll find that those corded tools, that most of us started with, have gotten better over the years, while the industry has moved farther and farther to battery driven tool market the corded tools have gotten the same improvements.

                        Would need to own it little longer to have better idea of how long it lasts, but so far so good.

                        The grinder works well. The registration IS HARD to complete because I bought it on line. I Am still trying to get it registered it at this time. If I can’t register it when my 90 days is up, I will return it!

                        Exactly the tool I needed to accomplish project at a reasonable price.
                        This angle grinder was priced reasonably and more than sufficient for an occasional user. I used it for grinding rust, old body sealer, and cutting old sheet metal out in preparation for installing new floor pans as part of old Jeep Cherokee restoration.
