## Description

Product Description Engineered for use in Glass, Regular and other specialty Tiles (Specialty Tiles that may be harder than normal ones).

Our product features an unique product geometry with a precision tip, high quality carbide and reinforced head that results in best-in-class speed and life when cutting in glass and tile.

Review: Worked Amazingly Well to Drill Through Tile - I bought these to drill holes in my bathroom tile to install a new toilet paper holder and towel bar (our entire bathroom is tiled from floor to about 6 foot high). In order to not chip the tile, I used blue painters tape to mark where the hole should be drilled. This tile drill bit cut a clean hole, no cracks and worked like a hot knife through butter.
Review: Powers through and keeps you centered/straight - I had to drill 3 holes in my ceramic tile fireplace for toggle bolts to fit in to devote my mantel. This type of bit was great as it stayed center at the starting point and powered through all 3 holes. You could feel it getting slower at the third hole but I bet I could have gotten a few more out of it before it was completely dead. Took me about 10 mins per hole, with a cordless 18V drill, and I was taking a few breaks for it to cool and to dip it in water to start again. Overall it was well worth the money and allowed me to wiggle it around the outer rim of the holes to make it a little larger so that the toggle bolt could squeeze in since it’s a tad over 5/8” with the pin. Will buy again if I need to drill into tile.

## Questions & Answers

**Q: can i use this on porcelain tile?**
A: Thank you for your question. The GT700 is not designed for Porcelain. The HDG58 diamond hole saw works well for Porcelain tile, Granite, Limestone, Ceramic Tile, Travertine, Marble and Slate. http://www.amazon.com/Bosch-HDG58-15mm-Diamond-Grit/dp/B003TO5F7W/ref=sr_1_1?s=hi&ie=UTF8&qid=1434401527&sr=1-1&keywords=Bosch+HDG58  If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

**Q: The description reads,'Chuck Size: 3/8 in & 1/2 in'.   Does this mean there is no reduced shank and I need a 1/2 drill for the larger bits?**
A: Thank you for your question. All of the bits included in the GT3000 will work in a 3/8" chuck, the shank is small enough that it will work in both a 3/8" or 1/2" drill chuck. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

**Q: Do these offer any advantages over a diamond hole saw?**
A: Honestly, I have used both and I prefer to use a Diamond-grit hole saw, but if price is a factor and you will be using multiple sizes this can't be beat. I have used Ridgid diamond hole saws and also Milwaukee diamond hole saws and I would recommend the Milwaukee ones. The only issue with these bits is they can "walk" on the material so you have to start slow and I also use water in a squirt bottle

**Q: Looking to buy and use one of these to drill a hole in a decorative dish to provide drainage for plants.  What size would be recommended?**
A: That depends on how large the dish is and what sort of drainage material you plan to use (aka "crocking" in gardening-speak)t.  If it's a large dish, I would definitely use some sort of screen in the bottom (fiberglass window screen works well, cut to fit) and a larger bit, anywhere between 1/4" to 1/2". If it's a smaller dish and you don't intend to use screen in the bottom, I'd use a bit between 3/16" and 3/8", depending on the potting material and what sort of drainage material you use in the bottom of the bottom.  Basically, if the holes are too small, they'll clog up, but if they're too large and your crocking isn't sufficient to hold back the soil, you'll lose it very quickly as you water the plant.
