i did all that shit for multiple hours, wd40, weezle piss, cobalt dewalt bits, wasted 2 of um in process, lot of force, slow rpm, fast rpm, recharged batteries many times over, tried everything, that last 1/8" just would not go threw. it finally did after i used some other bits and ate at it lil by lil but id deff do it different next time with a bit like he used.
