Review on Bosch HC2084B25 25 Piece SDS Plus Bulldog by Andrew Dinelli

I just built a 20' x 30' Quonsut style steel building and had to anchor it with over 1 wedge anchors drilled 1/2" to my foundation attach. 4 1/2" deep. Our uncles erected a similar building twice the size and said they went through almost half a dozen things. Well I didn't want to be alone as I was an hour from the nearest hardware store so instead of individual bits I bought a set of 5 and an SDS punch from a port freight.To my great surprise I've drilled all 80+ holes and I'm still on the first bit and it looks barely used!What now with more than 4 Bits Do The bit went through 3,000psi of concrete and no noticeable damage to the bit.
