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: Works in hardened steel - Used bit to drill out an easy-out that broke off inside an aluminum engine block. It worked great. It was the only thing that would drill through that hard of steel. It was a 6mm bolt and did a good job of staying centered in the steel and not wandering into the softer aluminum block. It is a bit slow, took an hour of non-stop drilling. Used water for lubricant. 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. ## Features - PRECISION: Features Bosch’s unique product design with a precision tip to help solve any bit wandering or bit walking - QUALITY: This glass and tile set includes a high-quality carbide tip with a reinforced head to reduce stress, prevent bit cracking and the diamond ground cutting edges provide a longer life - VERSATILE: Perfect for common applications such as relief holes for glass cutting, bathroom and shower installs, drilling and fastening mirrors, setting concrete screws in tile and many more - RELIABLE: The three flat shank provides superior grip on 5 16 in. bits and larger to prevent slippage.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works in hardened steel *by C***S on May 26, 2026* Used bit to drill out an easy-out that broke off inside an aluminum engine block.
