Cutting Aluminum siding
 
I need to cut a circular hole ( approx. 2 inches in diameter) in existing aluminum siding and want it to be neat without tearing it .How do I cut this hole,quickly and surely ?

Use a hole saw (bit) attached to a corded variable speed drill. A hole saw bit is circular, like an empty tin can. Use one with metal style cutting edges. Look in the Drill bit department at your local hardware supplier.
Don't start off going full speed with the drill, try it at about 1/2 - 3/4 speed and adjust it up, once you get the circular cut started...

Good Luck!

Better late than never, and hopefully will help someone else searching....

I like to do as noted above but I simply start the drill bit (slowly as mentioned) to make the pilot hole, then I run the drill/holesaw in reverse to get an accurit start on the actual hole (this will start your trench without skipping around damaging the surrounding soffit or siding).

Again, take your time and watch your drill speed. Once the groove is deep enough (and if your not able to complete the cut in reverse) return your drill to forward and gently finish the hole.
