stevenjd 21st July 2022, 08:14 PM Hi, has anyone tried using the 3M Scotch-Brite wheels for their 8” grinder. I saw one being used on YouTube and it seemed very impressive. I have 2 grinders, one with 8” grinding wheels and one that is a buff.
i haven’t even turned either of them on yet. But i know I want to change one of the grinding wheels and one of the buffing wheels. After watching the YouTube clip using the 3M Scotch-Brite wheels i was very impressed. Has anyone tried the Scotch-Brite wheels from 3M.
BobL 21st July 2022, 08:40 PM I been using the scothcbrite from ABtools for about the last 5 years.

Usually I buy one 8" scotchbrite wheel about every year alternating between medium and fine every 2nd year.
I like to get the 6 or 8 flap wheels but sometimes they only have the 4 flaps so I buy two and join them together.

I use the medium ones for rust, paint and small burr removal.
The fine wheels get used for brushed finish on Stainless, Al and brass.
SWMBO uses the fine one on some of he jewellery bibs and bobs.
stevenjd 21st July 2022, 09:04 PM Sounds like a plan Bob. The YouTube demos look great…but the Scotch-Brite wheels seem pretty rich. I think your approach looks really good.
I meant to ask….how do you attach them to your bench grinder…mine is i think 20mm dia.
BobL 21st July 2022, 09:22 PM you buy a buffing wheel spindle that has a female thread on one side and screws onto your grinder spindle, and the wheel screws onto the tapered tread on the other end - look at my photos again
stevenjd 21st July 2022, 09:28 PM Thanks Bob I looked a little closer at your pics and worked it out. i have ordered the fine ,med and course x 6 pads..so fingers crossed.
Cheers and Thanks.
China 21st July 2022, 09:40 PM I have not used 3m wheels on a bench grinder, although I have used hundreds of their belts over the years, and discs on angle grinders and polishers never had a problem with them unlike some of the other "top" brands
Tonyz 22nd July 2022, 06:35 PM I was using one whether 3M brand I dont know on my angle grinder removing severe case of rust on stair railings on the sea coast.
I didnt realise what a power job it was doing until I realised I couldnt see anymore, plastic face shield, personal glasses all with a ugly brown haze over them.
The downside was the 'blade cover' wouldnt fit and my finger tips show proof of.
