Hi, defintely new to tractorbynet, and new to many things power tools. Right now, I need to use a #55 drill bit (.520) I think, and it is too small to be used by my step dads drill. I think I either need like a mini-drill for really small bits or some sort of adapter, that will help the #55 drill bit fit into my step dad's big drill. This may be a super elementary question, but you might be surprised at how much research it tookto even find out that I maybe could use and adapter, which would be great. By the way, I don't know y step dad's make and model number, I think its craftsman, but from the little I know about power drills, is that it looks very standard for typical drill bits. Any help?

Welcome to TBN.... good question!
Well, I had to look up a drill bit chart to make sure...here's the chart I used..
Drill Bit Size Chart
size is .0520 inches... the leading zero makes a difference...this is a rather tiny bit.
if you are going to be doing much work with tiny bits and tools, suggest you simply fork over a few bucks and get a tool that is sized for this job...with appropriately sized chucks, etc... look into things like this..
Dremel is the premier standard for such tools.
4000 High Performance Rotary Tool / Model: 4000
Harbor Freight, if you have one in your area, has lower quality tool with similar function.

yep, rotary tool.... has a small chuck that takes small tools, drills, grinders, saws, sanders, etc...
this is the kind of thing that numerous people have... ask a few friends, you may find someone who has one they will lend you for a one time use.

Welcome
I had to use a small bit while ago and no chuck would hold it. It was actually smaller than yours - for carb venturi - but I put masking tape around the shank and used my regular chuck. The bit is flexible and if you are careful you can get away with it.

You might even try one of those small stirring straws you get with coffee and such. Cut it off to about 1/2 " then put the bit in the straw and see if the drill chuck will clamp it tight enough. That small of a bit is going to break if you bend it much at all whilst drilling.

If it's a 1 time thing try the straw or tape, just take your time. Otherwise A dremel tool will work and you can find cheap ones.

If you are drilling something soft or thin, there is a mandrel type tool that is like an exacto knife, that will hold a small bit and rotate it by hand. I have even flattened and sharpened a straight pin and used it as a bit.
Another option would be to take a brass tube, like from a hobbie shop, and split it and use it as a reducer when chucked in a drill.
