why can't you find cut off wheels that will fit this particular tool? I have searched in store and online as well. There are no cut off wheels that fit 4 1/2 x 5/8 (arbor size) . there are 7/8. How can this be a cut off tool when there are no blades that will fit?
Asked by: arf
When you remove the round nut, you will see a very shallow area below the 5/8 arbor. That area is 7/8". You put the 7/8" cut off wheel or grinding wheel on and it will slide over the 7/8" area. Then put the round 5/8" threaded round nut on and tighten down and it will lock the disk in place. I have two of these 4-1/2" grinders. If you have issues with the disk spinning while tightened down, you may have to add a washer between the cut-off wheel and the round nut. That depends on how thick the cut-off wheel is. I've seen some that were very thin and I had to use a washer. Make sure the washer has a hole in the middle that fits snuggly over the arbor.

Is this the grinder/ cut-off tool version?

Asked by: Vicki
Thank you Vicki for your inquiry. The P423 is designed to be both a grinder as well as a cut off tool. Make sure to reference the proper sets and safety precautions before beginning any job. ~best regards, Ashley

does this kit come with a free tool?

does this kit come with a free tool?
Asked by: Chester
The AD says that I do, but I haven't received it yet and customer service says that they don't know what I'm talking about. I guess I'll wait and see when it gets here. It could be a Ryobi nail clipper.
