Which Scotch Bright wheel?

[Larry$]

I just ordered a new bench grinder and want to use my old 8" one to debur and/or polish. Looking at all the different Scotch Bright wheels available I have no idea which one(s) to order. Help!

I have the same question... I ordered one back in Dec 2021, and more abrasive than I wanted...

This is the one I am using now... but strictly for deburing... if not careful, it will remove material quickly...

3M 64900 General Deburring Wheel - Max RPM: 6000, 6X1X1", Grade: 9S FIN

This is the one I use. Expensive, but it holds up well and does a great job.

I remember buying my first one for $25, several years ago, and being surprised by $75 price tags more recently.

Now it's $83. How old is this thread, an hour? Man, this inflation!

This brochure from 3M may help in deciding which type of deburring wheels to purchase. Personally, I use their Scotch-Brite convolute "Light Deburring Wheels".

They are soft so they don't grind away the square edge on aluminum and do take off the burrs with light pressure. I also use them on 316 stainless. Stainless takes a little more pressure but still produce a nice crisp edge. They probably wear faster than the EXL or EXL Pro's, but mine are going on 10 years old and have barely any noticeable wear. I would avoid the more aggressive wheels. They tend to dig in and ruin a crisp edge if uneven pressure is applied.

I bought a 3M 6" wheel maybe 6 months ago, called a "medium deburring", and it's been just about perfect. Around $50 as I recall.

Anyone had experience with these?

Because I use it on aluminum, it seemed like silicon carbide was the preferred abrasive.
