Bosch HCBG800 Blue Granite Eight-Piece Hammer Drill Bit Set:

Great Drill Set. These really cut through concrete in short order. And the really great thing is that they stay sharp, even after 'several' holes. Bosch out did themselves with these, they really live up to the Bosch reputation.

Was very happy with these bits!:

I used these bits for over a year and was very happy with them. Used them to drill into concrete, plaster and block with great success. The only problem is, they came up missing while doing a job with my son-in-law with other contractors on site. I think someone needed them more than I did. I will re-order these bits from Amazon soon. After using some bits from another company, I realized how good they really are. I would recommend them to someone who does it all like me.

Drill set by Bosch:

THis is a great drill set with all the usual sizes. The bits seem to last forever.

works great:

Just used the 1/2" and was as good as a large hammer drill, works great.
