It IS maddening to drill, especially a very small bit,, Believe it or not,, I sometimes heat it to a dull red, and then drill it,, when using a very small bit,, It heli-arc welds like it WANTS to be welded,, lolol,,, I usually don't even wear a helmet, but clamp a shade onto a magnified lamp, and look through it,, I've used electrodes as small as .020,, and make fuse welds that are nearly invisible.. I LOVE working it,,
