What Customers Are Saying
Customers report mixed results with these tile drill bits. Most praise their ability to cleanly drill through ceramic tile for shower installations when using proper technique—medium speed, water cooling, and steady pressure—with many achieving multiple crack-free holes. However, a substantial group experienced premature failure, with bits breaking or dulling after just one to five holes, particularly on porcelain. Several note the bits work well for occasional use but suggest investing in a higher-quality set for frequent projects. Overall, reviewers remain divided between strong satisfaction and frustration with durability.

Bad for Porcelain maybe good for glass and ceramic
As far as porcelain tile goes these are terrible I know they are meant for glass and ceramic but I bought identical ones from another brand and they worked great on the porcelain. Maybe they would be worth it for glass but for tile they literally wouldn't even start a hole.

Great for Ceramic Tile
Would RecommendSo pleased with this bit. Had to install glass shower doors and handicap grab bar in a tiled shower. Worked beautifully, no cracked tiles.

Use water when drilling a glassy surface.
Would RecommendGreat buy. Four bits for less money than two would cost separatley. They really drilled though glazed ceramic tile with ease. Much neater and more accurate than just using a masonary bit.
