I recently picked up a box of bits from my brace and along with the countersink bits that I was really after, I found a good selection of standard twist drill bits with a square drive to fit in my brace. The sizes are in the 3/16-5/16 range.

My initial thought was that twist drills would typically require higher speed than I can provide with a brace. Perhaps these are to be used in something else.

Anyone out their using this type of bit in their braces? How is it working?

Of course I do realize that I could just pop one of these in my brace and try to drill some holes but I am interested in knowing more of the intended use for this type of bit. Would they typically be for wood or metal etc.

I can post pics if anyone is interested.
