  • Changing Ridged 4.5" Cordless Grinder Guard

    Hello!

    New to the forums and new to the ridgid line of tools. I'm just wondering if anyone has found any 5" guards that I could adapt to fit the grinder to run 5" cutting and grinding disks as that is what's provide at work, or am I stuck with buying a Milwaukee cordless grinder?

    I would be careful changing the wheel diameter. The rim speed of a larger diameter wheel at your grinder's RPM may be exceeded. When that happens KABLAMO!, things start flying apart and it ain't pretty. The guard is sized for best performance when the tool is used with the diameter wheels it is designed for.

    So be sure any wheel you choose to use on your grinder, regardless of it's diameter, is rated for MORE than the Max RPM of the tool.

    This is the main reason these tools use different hub or spindle diameters, so people can't accidently mount the wrong wheel on their grinder. Notice I said accidently because there is always a way to defeat any safety function built into a tool. Just as any lock can be picked. But just like a lock when you defeat that safety function you have knowingly made the decision to do so and assumed all risk for your safety.

      Yep I'm well aware of rpm and rim speed. My question is simply has anyone found a 5" guard(possibly Milwaukee) that fits onto the Ridgid 4.5" cordless grinder.

        Surely there's someone who's done this swap before

          There may be, but you just got here. This place has been pretty slow for the past couple years so you may not realize that the number of members who check in here AND take the time to comment is low. Like fewer than a dozen a day. Everyone is too busy with their own lives I guess. Lots of guest check-ins but they can't comment so not going to help you.

          You'll probably get an answer a lot faster on a metal-working forum or FB group. Or just do some searching online for yourself will probably turn up something.

          Not trying to chase you away just stating a fact.
