To perform best results of Dremel 8215 Aluminum Oxide Grinding Stone, Dremel recommend users:
• Use the 415 dressing stone to clean the surface of the grinding stone and restore its original shape. You can also use the dressing stone to create a grinding stone with just the right shape for that special job.
• For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collet or chuck to hold onto the bit.
