personally, make the slots with something else, then finish with a file. Or get an end mill and use that in the drill press. You need to cut on the side, and drill bits aren't meant for that.
a solid carbide one would flex the least.
If not, DEEP center drills, pilot drill, then drill to size. If possible, retain some meat so that it's not a finished slit and remove that later. It should help with the bending of the drill.
clamp it tight, and minimize quill extension.

I have the drawings done.
Just have to convert to some useable format for you to print out accurately.
Do you have Sketchup or e-drawings viewer?
If you do, it will be more accurate than bmp, jpeg or png file conversions.

A single ended HSS 4 flute endmill works great for this job even if you don't have a mill. Might be on the pricey side but you don't need a high quality one, just one with a same size shank. High speeds and light feeds. Aluminum should be a piece of cake to do this to even for a novice.
I finshed drilling 2 month and 4 hours ago so it dosent matter i than powder coated the aluminum and it looks great also alot of people dont apreciate when you post in a dead topicOxbreath wrote:Why are you drilling those ?
Just use a hacksaw and then a round file.
dont play with airsofter with 1000$ gun and play with a 5 dollar pair of glasses

Someone else might find this thread in a search, and appreciate an easier way to get those slots cut in the barrel.
No one minds if a 'dead topic' is posted to... If something constructive is posted.
If you can't fix it, you don't own it.
So why not show some pictures of the end result?twizi wrote: I finshed drilling 2 month and 4 hours ago so it dosent matter i than powder coated the aluminum and it looks great also alot of people dont apreciate when you post in a dead topic
Ask for help and you get it, but no results from you to show others that it is possible.
I was about to revive your 'dead topic" anyway to get an answer.
