DeWalt 20V MAX DCG412B Lithium Ion 4-½” Angle Grinder, First Use, Review, Allen Key Storage

I try out my new Dewalt DCG412B 20V MAX Lithium Ion 4-½” grinder. I review the product, test with different discs, including a chainsaw chain disc. Also I I added a great idea to store the Allen key in the handle. Allen Key Hack for storage.
