Hi everyone. I have a 250W, 150mm Ryobi bench grinder from a few years ago, model RBG6G. I am trying to find out if I can replace either of the grinding wheels with polishing/buffer wheels or a wire-brush wheel to improve its versatility. I appreciate it is not very powerful motor so may not have the torque to polish or clean, if anyone has any experience or thoughts, please chime in and let me know before I spend any more money!
If I can fit other wheels then I think the money would probably go towards Bosco products as they have a wide range of polishing wheels and compounds, as well as a selection of wire cleaning wheels and brushes. They also sell tapered spindle adapters, but, as I said, I can't figure out if they can be fitted to my ageing little grinder.
John.
Hello @VulcanJohn
Thank you very much for sharing photos of your Ryobi bench grinder. There might be restrictions on the type of wheel that can go on the grinder. Allow me to investigate further, as soon as I have more information I will post it here.

Good morning Avro @VulcanJohn
"I appreciate it is not very powerful"
I have a 100 watt bench grinder with a wire brush (125mm) and it's worked extremely well for twenty years on small items - but I have no polishing experience.
Hi @VulcanJohn
I've just been in contact with the Ryobi technical department and they have informed me that if you use a polishing wheel, make sure that it is the same size as the grinding wheel, which is 150mm in diameter and at least 20mm thick. It should also be able to take the same rotation speed as the grinding wheel which is 2850 rpm and must have the same diameter mounting hole.
Just to be on the safe side when you purchase the Josco polishing accesorie, please make sure to do a test fit and keep the docket just in case you need to exchange it.
If you need further assistance, please let us know.
Eric
