DeWalt611 Drillbit Collet?

Is there such a thing as a Dewalt 611 Drillbit Collet? If so what is it called?
I want to use my drillbits for drill patterns, not the endmills.

Thank you for the reply, I did see the jeweler drill bit set however 1/64-3/64 isn’t big enough for what I want to do. I’m looking for 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64, and 1/4 in. I picked up this set:"+shanks but the 1/4" shank is larger than 1/4" on the corners of the shank. It doesn’t fit my 1/4" collet.

@RobertCanning I’ve used 1/8" and 1/4" regular bits with better success than endmills.
