Review on Bosch HC2012B25 25 Piece SDS Plus Bulldog by Nathan Ortiz

I drill a lot of holes in concrete and these Bosch drill bits are the best. They last longer than Dewalt and definitely outperform the cheap ones you get at trade shows etc. These bits cost a little more but last so long that you actually get more value and a cheaper cost per hole. I've used a lot of tips that literally melted heads, but they have a great design and the tips stick to the shaft really well.
