Absolutely. Drill as far as it will go. Snap off the core in the middle of the hole using some type of wedge such as a slotted screwdriver. Remove the blue water dam as the hole will now hold the water. Repeat this process as necessary. With a drill shank extender there is no limit to the thickness you can drill but it will become tedious.
yes if you are careful
If you mean drill with keyless chuck. Yes
Yes! I just used this to drill a perfect hole in an enameled cast-iron kitchen sink. I cut a hole to install a soap dispenser. It worked great!
they can be ordered on line
You need to go slow if you drill glass, and keep the water in the delivery device. You know you have enough when an opaque slurry forms. Gently lift the drill bit enough to allow the water into the groove. You will burn the bit and damage the 'diamond' coating if allowed to run dry.
I used a cordless Ryobi drill and it worked fine. You don't want to put too much pressure as you core through anyway - but you DO need to "push". If you are slowing a corded drill down significantly, you are probably putting too much pressure on it.
I used it on a granite slab with an 18v brushless Milwaukee. It only took about two minutes to go through the slab. Very clean and neat hole. Would highly recommend
If the water receptacle is holding the water through the entire filling process, I'd say excess pressure or uneven surface below the tile are the likely culprits. I've used this on porcelain tile, ceramic tile, granite and quartz countertops and haven't had any cracking. You should also make sure the cutting edge doesn't have any dents or is out of round, in case that is creating an increased pressure on the tile.
I used this tool to cut porcelain tile, but I'm not sure if it would successfully cut through glass. Only one way to find out.
