This bit is a masonary bit to be used in a hammer drill. It is a good quality bit from a company that is known for quality tools, esp. when it comes to hammer drills.If you were only making a small number of small holes in masonary, say for anchors, you might be able to use a standard drill with non hammering masonary bits. But if the job calls for larger quantities or larger holes, Step up to a hammerdrill with hammer masonary bits like this one.

I have used this bit to drill through concrete block foundation walls in order to feed conduit and wires to exterior outlets. This bit when used in conjunction with a hammerdrill, made the holes needed much faster than a rotary non hammer masonary bit in a non hammer drill.
Bosch bits seem to stand up to tough use better than the B&D/Dewalt bits that I had previously used. The Shank of the bit is reduced down to fit in the chuck of a 1/2 inch hammer drill. So you cannot use this if your hammerdrill has a 3/8 inch chuck. Also, I use this bit in a Ridgid Hammerdrill that is rated for this size bit. Many other brands do not generate enough power or torque to turn this large of a bit, so check the specifications on your hammer drill before using it with this bit or you could risk damaging the tool. I would resist the temptation to try using this bit with a cordless drill for the same reason.
Bosch bits are easily found at most home centers.
