You can also drill the holes in two stages - the first close to final size and the second at final size. This will reduce the tear out substantially because you’ll be cutting most of it away as the hole gets to final size. It doubles your drilling time but depending on your application, it might be good enough. “Good enough” here doesn’t imply low quality or hacky, it means good enough for the requirements of the design, the material, the time you want to spend on a specific operation, all that; everything is a tradeoff
Following @EricH advice of a reduced feed rate will help but it’s very difficult to prevent this problem when you are drilling unsupported like this but if you need really clean insides, you’re going to have to debur the insides in just about any case).
As you get very close to completing holes like this, the behavior of the material you are cutting gets unpredictable - some holes will be close to perfect and some will end up with burrs not matter what you do.
Finally, do you really need every hole there? Like the entire pattern? That’s a lot of time, electricity, tool wear or breakage, etc. I’ve rarely found it worth it to make things like that which are sort of “stock” parts - if you need a series of holes in a specific area, you might be much better off overall just making the holes there and leaving the rest solid. Think about whether you are making a part for a specific design or making parts that have a lot of “just in case”. It’d be a shame to spend all that effort and find out when you use it, you really need spacing that’s offset by a 1/2 or 1/3 from the existing hole pattern.
You could even make the parts with just the holes you need for the mechanism and later do a second operation for specific hole patterns once you’ve got a specific scenario in mind.
Sometimes “can” needs to weighed against “should”. I’ve spent time and money making general parts that I thought would be “good to have” and then when it really came down to it, they didn’t fit my specific scenario and I thought about all that time and material…
