5.0 out of 5 stars A great bit, January 24, 2009

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.

when used with a corded hammer drill, it goes through most concrete like butter. Older and harder concrete make the job tougher, but it still works great.

I was very impressed with the high quality of this bit. It makes the hardware store brands look like toys. I was using (not for intended purpose) to drill hardened lawn mower blades and the hardware store bit completely failed (unusable) after one blade. This bit drilled eight before needing sharpening of the well mounted carbide tip.
