Meet my friend Brad, he's a pilot
The drill bits I break the most are the 1/8" ones I use for pre-drilling. Probably because I keep buying those cheap Ryobi bits (I like the hex shank), and I never stepped up to a more expensive bit because I assume I'm going to break it anyway.
Well, consider my game changed. From woodworking madman Izzy Swan comes this useful tip: How to drill pilot holes without using a drill bit at all!
Jeez Louise! The brad nail I could see working, but the framing nail? I wouldn't believe it if I hadn'ta seen it. And while I guess this is more of an "If you're in a pinch" tip as opposed to a permanent replacement for drill bits, this is bound to come in handy when you're working on something after the hardware store's already closed.
