Carbide-Tipped Glass and Tile Drill Bit Set (8-Piece)

A:  No! As indicated in the description these bits are meant to drill glass and ceramic. And they work well.

A:  No, they are specifically designed for glass and ceramic tile.

A:  The GT2000 is designed to drill though glass and tiles. For metal, we recommend a cobalt drill bit. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

A:  This GT3000 is a glass and tile bit that should be used with a starting RPM of 200. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

A:  While Bosch does not specify maximum RPM's for these carbide bits, one would have to ask several questions in any attempt to respond correctly. What material are you drilling? For example, the glazing on the tile is significantly harder than the core. There are way to many possibilities in stone for countertops to begin to answer your question. Again, to use another example, granite and quartzite are very hard, but on the Mohs scale of hardness (from 1 to 10, with 10 being hardest) quartzite is slightly harder, so it would be much more difficult to drill through. It measures around 7 while granite is lower at around 6 to 6.5 Are you using any form of coolant like a water mist? That too would change your answer. So, we need more information to provide you with a real answer

A:  I used them on regular bathroom tile. I presume that is what you mean by porcelain.

A:  Not easily . Hope you have lots of time and energy . Diamond bits are the way to go for tile .

A:  I used it on standard bathroom tile. If that is what you mean by porcelain, yes.

A:  Hi there! The GT3000 Glass and Tile Bit Set is designed for glass and some tile materials, however, we recommend using a diamond hole saw for drilling porcelain. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

A:  Yes, however you can drill a better hole using a regular drill bit starting with a smaller size and working your way to the larger size hole. It would make a cleaner cut.

A:  The GT2000 Glass and Tile Bit set only drill through glass and natural stone tiles. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

A:  Plastic is always a pain and a crap shoot. They bits are more than a match for plastic of any and all types, but drilling plastic near the edges such a crap shoot when it comes to the plastic breaking. In the past when i have had to drill plexiglass, i have used a regular bit, and started with a smaller size and made the hole larger till it got to the correct diameter. If you are dealing with the 1/16" plastic, i would avoid holes ealtogeter. I recently made a 2' x 3', six compartmet display front for a t-shirt seller. He had the thin plasatic and so i glued it only - no holes for me. Would i use these bits on plexiglass - NO!
