I think I've mentioned this once or twice before. I use my Dremel Motor more than any other tool with the possible exception of my welding equipment. Yes you can "drill" through plates to make garden flowers with a regular drill but with the Dremel motor you can easily drill through curved surfaces (like Bottles) and you can make the hole any shape. The $50.00+/- is well worth the price.
Disclaimer: Nope! I don't work for Dremel nor do I have any investment in the company. The Moto tool at Harbor Freight is too small - in more ways than one.
