After drilling an initial 10 holes with each bit, we inspected them for dulling and wear before drilling more holes. We did not judge the bits on how long it took to drill through a tile because different types of tile require longer drilling times, and it’s counterproductive to exert strong pressure while drilling as it can cause the bits to break. We looked for durability and relatively smooth-edged holes-it’s not unusual to have some slightly ragged edges, however. The better a drill bit performed, the higher the score. We scored each bit (or bit set) using a rubric throughout the hands-on testing process. Our goal was to determine how well the bits stood up to their intended drilling purposes. In short, we did not test a bit made for drilling ceramic or glass tiles on porcelain tiles, which are much harder. We tested the bits by drilling multiple holes, but we only tried them on tile types they were designed for. As the manufacturer suggested-or if a bit was struggling to drill through-we added a few drops of water while drilling to help keep the bit from getting too hot and breaking. It’s not always necessary, so we didn’t tape all the tiles-for example, the surface of a travertine tile is soft and porous, and most bits will not wander when drilling through travertine. We used masking tape on the tops of some tiles, which can help keep bits from wandering and reduce the risk of the tile chipping during the drilling process. All of the drill bits were tested using a standard cordless drill. Our actual testing process was straightforward. We considered the brand to an extent-DeWalt and Bosch are both top manufacturers of construction tools-but didn’t automatically eliminate drill bits from smaller or niche manufacturers if they featured carbide or diamond tips and were rated well by consumers.
Over the years, we’ve had plenty of practice drilling tile, so our experience combined with in-depth product research was instrumental in selecting the drill bits for testing.
