What Customers Are Saying
This diamond-coated drill bit performs well for drilling clean holes through ceramic, glass, and tile materials, especially when used with water to keep the bit cool. However, it can be challenging to start the hole and keep the bit steady, particularly on porcelain tiles. Users recommend starting the hole at an angle, gradually straightening the bit as it cuts, and using a low drill speed. The bit may wear down quickly, especially on thicker or harder materials, so it's best suited for light to moderate use.

Paid more $ for something better that was not.

Junk
Would Not RecommendTried to drill a hole in tile. The bit was burnt out before drilling 1/4 tile hole. $19 down the drain and I have 6 more holes to drill

Ceramic Tile Bit cuts like a charm
Would RecommendBit created a nice clean hole in the tiles, including edge cuts that ran off of the tile. There was no significant chipping and the bit didn't noticeably try to pull the workpiece out of my hand as it started to cut. Job quality earned a 5-star rating. The lost star was due to the waste being hard to remove from the bit after the cut was complete. Finished DIY job looked professional. Perfect size to hide holes but work on plumbing in the future.

Cuts a nice smooth hole
Would RecommendThis cutter performs better when water is added, it will also cut dry. Will need to cut a hole with a drill bit in some scrap wood otherwise this bit will wonder all over and then clamp it to the tile piece for easier drilling

Excellent tool
Would RecommendThis was perfect for cutting the openings for the shower and tub copper tubes in ceramic tile on a shower install. Just make a wood template to hold it in place, clamp it, and use some water to keep it cool. Worked perfectly for two cuts. IDK how it would hold up over frequent use, but well worth the price.
