Install 3M Sandblaster Disk on your angle grinder

In this video I show you how to install the 3M Sandblaster Disc onto your 4 1/2" Angle Grinder. Once installed you can attach various discs without the use of tools.
 I use my Ryobi Angle Grinder in the video but this applies to almost any angle grinder 4 1/2" or 5 1/2" with a 5/8", 11 thread per inch external shaft size.
