Good for wood, not much else (n/m) - jkperformance 21:22:33 07/27/13 Kobalt is better than HSS, but not as hard as carbide. - zellamay 08:15:47 07/28/13 Kobalt is a brand. cobalt is what you were thinking, prob (n/m) - jkperformance 16:09:38 07/28/13 Yes, I was thinking matl, not brand. - zellamay 17:34:18 07/28/13 You're not snapping the bit because it's weak - BlackholeZ 15:15:31 07/28/13 It's definitely proving to be a challenge. - rojoloco (VA Beach) 21:23:46 07/28/13 A picture really might spark someone's imagination. (n/m) - zellamay 01:42:52 07/30/13 Is there enough room for vise-grips? (n/m) - -Grimm- 14:40:23 07/29/13 Drill-Out extractor, bit built-in, reverse threaded - Ron(Houston) 21:46:16 07/31/13
