Hello
I would like to buy a dremel or similar to file the ends of my earwires but are not sure what tool and drillbit I need. I saw this one from cookies - Dremel-300-Tool-In-A-Tube-Dremel-300-With-Speedclic-prcode-999-3209.

Can someone please tell me if it has the bit I need to file the ends, or is there another tool that would be better for me to use. I make around 50 pairs a week. Thank you, Meli
