4" coring bit
The bit worked great and was a terrific price. It went through brick and concrete block as described, with several breaks to cool off my hand drill that I used for the project. I would definitely recommend this product for its performance and very competitive price. Be sure to wear a good mask to prevent silicates from getting into your lungs and ear protection. It will be loud! When receiving the bit, I was concerned that the diamonds supposedly on the cutter portion of the bit were absent from view, but it really did the job with very little wear upon the tool.
