Less Aggressive --------> More Aggressive
7445 7448 6448 7447 6444 7446 7440
Finer Finish --------> Coarser Finish

(The CAMI grit value is directly from 3M. The FEPA value inside the parentheses is the equivalent.)

7445 - White pad, called Light Duty Cleansing - 1200-1500 grit CAMI (Talc) (~2500 grit FEPA)
7448 - Light Grey, called Ultra Fine Hand - 800 grit. CAMI (Silicon Carbide) (~1600 grit FEPA)
6448 - Green, called Light Duty Hand Pad - 600 grit CAMI (Silicon Carbide) (~1200 grit FEPA)
7447 - Maroon pad, called General Purpose Hand - 320 grit CAMI (Aluminum Oxide) (~320 grit FEPA)
6444 - Brown pad, called Extra Duty Hand - 240 grit CAMI
7446 - Dark Grey pad, called Blending Pad 150 grit CAMI
7440 - Tan pad, called Heavy Duty Hand Pad - 60 grit CAMI

Blue (pad/sponge combo) Scotch-Brite is considered to be about 1000 grit CAMI (~2000 grit FEPA).
