Looking for collets

[63VDub]

My Rusnok takes DA100 collets, and I'm looking to add a set so I can do stuff. What sizes and brands do I need to be on the lookout for? Do I need 1/32" thru 3/4" by 64ths? Should I pick a few common sizes and call it good? would this be a decent set to start off with:

Thanks for entertaining my questions.

Shanks for endmills don't span that huge of a range for those 3 would get you by for quite some time probably 3/8 1/2 5/8

For drill bits its best to use a chuck.
