Customer Questions & Answers

How long should this last?

I drilled two holes in ceramic tile and it is so dull I can not start a third hole. Is this supposed to be working like this?
Asked by: carydf
There are too many variables to determine how long the bit should last however you definitely should be able to drill more than two holes into the tile. We recommend contacting our Product Specialists at 1-877-267-2499 so we can further discuss the issue you are having and possible options we have available to assist you.

5/16 in. Carbide Glass and Tile Bit is rated 3.9 out of 5 by 14.
Rated 5 out of 5 by from Used this bit for a different purpose than designed for but work, with caution. I used this bit to drill holes in glass bottles for a craft project. Works but must go slow and very slow when making final penetration through the glass. I normally use a different type of class hole cutter but this is much less expensive and decided to try.

Rated 5 out of 5 by from super sharp tile bit Was a one time use purchase for me which performed admirably. Clean precision hole which anchored down a pillar in our family room. I would like to commend Karen in the kitchen design dept. She led me right to the product. Very professional.

Rated 2 out of 5 by from Not worth the cost. Managed to get 2 holes drilled before the bit burned out. I drilled floor tile. Used a slow speed and kept the bit and surface wet. Ended up going to my local hardware store, bought am inexpensive bit hoping to get through the remaining 4 holes. The cheap bit zipped right thru and still had life left in it as I ended up drilling an additional 6 holes in wall tile. This was not my rodeo when it comes to drilling tiles and glass! Would not recommend.

Rated 1 out of 5 by from Does not last very long Drilled two holes in ceramic tile and its too dull to use any more.

Rated 5 out of 5 by from agonizingly slow in porcelain tiles, but doesn't wander just almost as painfully slow as the M. 5/16 diamond hole saw, which costs twice as much. I use this tile bit to drill deep enough so the diamond hole saw doesn't wander anymore so badly, then I use the diamond hole saw. The diamond hole saw is just marginally faster, but when it takes REALLY long to drill a single hole, any advantage helps.

Rated 5 out of 5 by from Great Bit This bit worked great to get through ceramic tiles. Didn't crack the tile so mission accomplished!

Rated 4 out of 5 by from Very nice bit This made short work of my ceramic tile, without any cracking of the tile. I'm not sure that it would hold up to a professional using it very long, but it is the perfect value for home use.

Rated 1 out of 5 by from Weak product The drill bit did not worked property it did not opened the hole on the tile... and the drill bit broke (the drill bit point). It was not happy with this product.
