I used these bits to drill through my 12 inch thick foundation to install some pipes. I would recommend picking up a SDS-Max hammer drill to do the job. I used a smaller SDS plus drill and although it worked, the larger size would have likely made the job much easier. I used the two smallest size bits and the largest bit and they all worked perfectly.Very happy with these bits. Just take your time when drilling. Use the hammer drill setting on your drill.

These bits have been great for drilling some holes through my foundation to run gas piping to an outbuilding. I purchased this set after having to return a different brand core bit that failed. I am very pleased with my purchase. The storage case is a nice plus.

Wow, went through my concrete block wall like butter. Great product, used the same size drill for two holes. No signs of getting dull yet. Recommended.
