We've been testing these babies out for about 4 months now and everyone who has seen them or played with them has fallen head over heels in love with them.
The 3M Electrostatic diamond disks are absolutely perfect for grinding and smoothing down smaller surface areas on your glass like jewelry and small scale work. They make short work of the surface and leave a virtually chip free edge even at the 120 grit. Quick, efficient and inexpensive, these disks will revolutionize many smaller pieces that you work on. You can also easily transition from either the 400 grit or 600 grit straight to the 3M Cerium impregnated disks for lightening fast polish. You won't know what you used to do without these.
