Yeah so I got this little ball drill bit more than a week ago. Its supposed to be great at drilling holes without clogging. Previously, I was hand drilling with those brittle tungsten HSS bits (which do snap when you least expect it, or expect it) on a Revell Kylo Ren Shuttle. It took me minutes to complete one hole. Imagine if I were to start on the Zvezda Star Destroyer.
So, I am hoping this would help solve the problem. The shank of this drill bit is about 2.3mm and therefore, I would fit snugly into my first micro polishing pen. I have now bought another, but with a 3mm chuck, which is great for my rotary saws, etc.
