Listing details to confirm

The listing gives a 2-inch bore diameter and also describes the bit as 50mm. It names brick and ceramic in the title and feature text, while the surface field lists porcelain tile, granite, marble, stone, masonry and concrete. Verify fit and the intended material before use. The product details call the finish type "Finish," which does not clarify the finish.
