Never heard of one, that is why they have egg beater drills.

Some brace drills will grip a 1/4” hex shaft of a “mini drill chuck”.

Lee Valley sells a hex bit adapter, which is handy when you’re using the brace as a driver; but I’ve never used the adapter with drill bits.

Yes, there are jacobs chucks that have a square shank to go in a brace, but you’re probably better off with an egg beater or breast drill.

Also Mr. Pink’s idea is good, you can put any hex 1/4” bit adapter in many braces. You’d need to buy a set of bits with 1/4” hex shanks that way though. I suppose you can put the 1/4” shank directly in the chuck too.

A brace is not good for very small drills. The small bits can be broken too easily because a brace is hard to keep on a spot while turning it. I don’t know how small a drill bit you want to use, but anything smaller than 1/4” is too fragile for the action of a brace. Besides, small twist drills don’t cut very well at such a slow speed. Were talking maybe 30 RPM with a brace.

A number of higher end braces will hold round bits. Also there are smaller bits that are attached to a brace end. A third option is a drill chuck that mounts in a brace. To Address Ron’s point about speed you could use a small sweep brace (5-6” sweep) to get more speed. The small sweep braces are also good for driving fasteners.
