How Much Run Out Is Acceptable On Drill Chuck

So you can't drill holes with a dowel pin, but you have gone straight to the conclusion that the problem is the drill! absolute right thing to do, then check your drill shank for burrs and skidmarks, hone them down, and try again, check the chuck jaws, and even strip clean and lube the chuck, you will get nearer all the time, but what you are getting nearer to is the original tolerance to which the chuck was made, not .000! the more time you take over checking the set up before you machine, the more accuracy you get
