Can use a Heule Vex-S (drilling + Chamfering in one operation) tool.
Bolt Hole Chamfers with an End Mill
As my CNC doesn't have an automatic tool changer, I'm always looking for ways to avoid bit changes during a job.
I had a project to cut out that has several bolt holes for 1/4-20 flat head bolts. I could have done the chamfers by changing to a V-bit or just doing them on my drill press after the CNC was done. I love a challenge though so I came up with this way to chamfer the holes with the same end mill I used for all the other cuts.

I've written up how I did this on my blog, Links to the file used to create the sample above are included.

I much prefer to let the CNC do all the steps needed before taking the board off. Eliminating bit changes means I can work on other things with no interruption until the CNC job is completely done.
