Grit equivalents for 3M abrasive pads

[Dan Gaylin]

[Apologies to all of this is a no-no: I posted a similar question in the “Finishing Forum” but no one seemed to know the answer so I thought this would be a better place as I suspect someone on this site does know the answer]

I have found the grit equivalents of the 3M “hand pads” as follows:

7445 - White pad, called Light Duty Cleansing - (1000) 1200-1500 grit
7448 - Light Grey, called Ultra Fine Hand - (600-800) 800 grit.
6448 - Green (?), called Light Duty Hand Pad - (600) 600 grit
7447 - Maroon pad, called General Purpose Hand - (320-400) 320 grit
6444 - Brown pad, called Extra Duty Hand - (280-320) 240 grit
7446 - Dark Grey pad, called Blending Pad (180-220) 150 grit
7440 - Tan pad, called Heavy Duty Hand Pad - (120-150) 60(?)
Common Green Scotch Brite Pad is 600 grit

The above list doesn’t cover the grit equivalents for the smaller 3M pads that are labeled more like steel wool with the 3 coarse , 2 medium, 0 fine, 00 very fine, 000 extra fine, 0000 super fine. These go green, green, grey, grey, grey, white. There are some color gradations in the greys I think.

Anyone know the grit equivalents for these?

Thanks!
