### ⭐⭐⭐⭐⭐ worked for the job

As describedEase of use:worked well

### ⭐⭐⭐⭐⭐ Worked
*by H***Y on June 17, 2025*

Served the purpose. Not sure it will cut multiple holes.

### ⭐⭐⭐⭐⭐ Drilling through brick
*by D***Z on April 25, 2025*

I had to make a hole in my brick wall exterior which is 4" thick. This hole saw cut through beautifully. Tips; Don't use the a hammer drill. It will only wear down the tips of the bit. If the brick is deeper than the interior of the bit, you will have to break off the drilled portion of the brick and pull it out in order to keep drilling in to the brick. It will take a few minutes to get through the brick using steady pressure. The result will be a perfectly round hole.
