I recently bought this set at this price not realizing how good it is. I used 7/8 last night regardless of where I drilled the camper style birdhouse to even it out I hammered in 2 end nails. I was like, "Well, I wasted that beat." I didn't damage it, I tried 3/4" cedar and 3/4" oak and it worked like I'd never touched nails. Thanks for a great product for the money!
