best diameter bit to cut 6061 aluminum

[anothernewbie]

We are cutting small parts out of 6061 aluminum and have both 1/4 an 1/8 O flutes. Both can complete the job. Is there one that you would recommend over the other?

1/4" less chance of breakage. 1/8" are so expensive if you break them.

I always use the largest diameter bit that will do the job... less flex, less breakage

Ha... steve we think alike!

Thanks everyone for the replies, that is what we had assumed.
