Is their a metal drill bit that will drill a hole but also be used like a file to elongate the hole.?
Question:ie make an L shape. and if so what is the name of such an item. trying to avoid drilling lots of holes and filing.
Answers:
We call them a saw drill, or rotary rasp.
Try you local hardware store.
there is no such tool.
You can get a "holesaw" bit for an electric drill. It's like a coarse round file designed to go in a drill chuck. Yoy will need s high speed steel (HSS) drill bit to make a pilot hole so you can insert the holesaw bit. Most tool stalls at markets sell them.
sure go to your local home center they'll fix you up . happy drilling
A rat-tail file may be the answer.
Can't remember the last time I saw an L shaped hole saw.
If your L doesn't need to be "pretty" or sized to any accuracy you could put a small end mill in your drill and "carve" the L. You can get the end mill at your local machinist supply house. This will be an ugly and difficult way to get the job done.
If you need accuracy in shape and size. Drill the L at it's three points and finish it with either a file, or jig saw.
There is no tool such as you describe.
I've used unibits for crude solutions to similar problems in thicker metals. http://www.hpiracing.com/graphics/tips/u...
But it sounds like a cutting torch may actually be better for what you want to do.
What you require is called a drill saw - for details please go and have a look at this web page :-

Perhaps those answerers above who said 'no such tool exists' would also like to go and have a look - so they will know next time.
There is one, because I have one, but I can't remember where I got it from.
The set Brian C points out is for wood so no use.
You could always use a Dremel, that would do the job.
depending on the gauge of metal you might consider a nibbler. they are available in pneumatic or electric.
