Bosch 3/8 in. X 6 in. Hex Shank Hammer Drill Masonry Bit LBHX008

I had a lot of holes to drill in concrete. These held up as well as other bits I’ve used before. The first couple I used got too hot and the carbide end fell out. I then started drilling a little and then cooling the bit in a bucket of water, they lasted a lot longer with that method.

Worked well in a brick for me although it was a pouris brick

Used with hammer drill went through brick almost like butter!

I bought this drill to use with a hammer drill drilling 8 holes X 2.5 inches into concrete for mounting a railing system outdoors. It worked great and held up even with the bit getting quite hot. It has already served my purpose, and I still have it for a future project. I'm happy...
