The Best Drill for aluminum sheet metal

What is best in an air drill for aluminum work on an airplane? #1 Speed, #2 User friendly, #3 comfort, #4 quiet, #5 reversible. For aluminum 2000+ RPM is needed. A drill that is user friendly will accept the drill and accessory sizes you need to use and will be easy to change bits/tools. A keyless chuck is the best way to accommodate this. A drill should be comfortable in your hand. A drill should be quiet. Some air drills like the Sioux palm drill are very quiet. Many builders are going to high speed battery operated drills which are also quiet. Reversible -- well, I threw it in but have never owned one myself. That's why it's at the end of the list. I've never seen a worn out reversing trigger on a used drill.
