- We all know you cannot drill or cut tempered glass, but how about drilling a hole in tempered glass using a precision instrument such as a dental high speed handpiece with a standard "Round" diamond burr installed? Let's try it!

I got almost all the way through with a 1/8" glass bit before the piece shattered in place and the cracks started spreading slowly for about 5 minutes. The window never collapsed and is probably still in place, but I'm sure it would take only a touch to make it collapse. I suspect that the problem is veins of glass that are under extreme tension pulling against veins that are under compression; once the drill cuts one of the veins, the release of the tensions causes a progressive collapse of all the other veins, so the piece shatters. Pot metal, in which different metals are only partially mixed so that they contract at different rates when they cool, can react the same way; it can even spontaneously snap without being touched. They both seems to have internal structures that behave like concrete with tensioned reinforcement.
Always fun to attempt drilling into tempered glass. :-)
The vulnerable point of tempered glass is the center plane (halfway between either surface) as it is under tension. Once this is disturbed the glass will fail, regardless of your technique.
so you must drill from both sides and meet at precisely the same time in the center?
Incorrect the most vulnerable points are the corners then egdes.
You are a jack of all trades.And I mean that has a complement. I used to clean my own teeth also. but these days my eyes are are to bad to do it correctly.
Thank you for all the very interesting and useful videos.

***** You're welcome. My vision is excellent for distance, but up close I need glasses for everything to be clear. Thanks For Watching!
You need to put some tape / plastic book covering to the place that you drill. Drill half of it with lighter pressure and turn around the glass. If you break the surface tension from behind it will shatter just like that. And if you can do it, the glass will always be very weak cause the tension is not there anymore.
Disclaimer: Don't do this! It is unsafe, etc, etc, etc. Don't even think about it!
Some years ago I was asked to attempt to "drill" a hole through tempered glass. I decided to try etching with hydrofluoric acid, as it seemed unlikely that drilling would be successful. A 1/2" long piece of 3/4" PVC pipe was attached to each side of the glass with hot glue, to confine the etchant. The PVC pieces were aligned exactly opposite each other. It seemed likely that it would be best to etch from each side to reduce the stress imbalance. One side, and then the other were etched with acid, alternately. Acid was poured into the PVC and left undisturbed for a few hours. The acid was carefully removed, diluted, neutralized, disposed of appropriately, etc, etc, etc. Next, the glass was turned over and etched in the same fashion. After etching each side a few times, it appeared that about 3/4 of the thickness of the glass had been dissolved. Before the next etch I decided to clean the glass being etched as there appeared to be some loose powered glass on the surface. Gentle scraping of the powder with a tiny screwdriver worked OK, until the glass shattered. Whether the glass might have been removed, leaving the desired hole, if not for the scratching, I do not know. If it were possible, I suspect that the glass would probably break unexpectedly at some point.
So... in addition to all of your obvious attributes, your a dentist as well?
You are one amazing guy
This video is great
Craig Nehring I have not been to a dentist for 7 years. I have been doing all my own cleanings 2x/year(and a much better job than they do). I also replaced several old stained composite fillings and filled a few pits in the enamel of my teeth using nano composite. I have all the equipment and supplies a dentist has to get the job done. I can assure you it is not an easy task working on your own mouth in a mirror using magnifiers. I am sure you have seen my dental retainer video as well. The teeth in the video are mine.
Thanks For Watching!
electronicsNmore Erm, no I have not seen your dental video, I'll have to take a look. That reminds me, I have a checkup the 28th. I put off a root canal therapy and it's been 8 months with no pain, hope the Xray shows it healed. Seems odd but I had been treating it myself with colloidal silver.
Craig Nehring Not every infection at the tip of a tooth's root requires a root canal, but of course a dentist will tell you to get a root canal. The usual treatment is antibiotics(clindamycin). If there is little bone loss around the tooth and there is no damage to the crown of the tooth allowing bacteria to enter into the pulp chamber causing the tooth to become infected, then it should be OK. A very good idea to use a chlorhexidine digluconate based rinse to avoid problems. :-)
That's a cool setup you have there. One of my favorite (and useful) tools is my Dremel. I'm sure having a dental hand piece and various burrs us like having a Dremel tool on steroids! Thanks for sharing this.

The answer is no, here is 5 minutes of your life back.
Could this be anything like Prince Rupert droplets? There is a lot of stress in the glass and for some reason when you break thru, the stress is relieved by the entire piece shattering. That would be my guess. I have friend who is a scientific glassblower, possibly I will ask him. Being a machinist I know there is a huge difference in hot roll and cold roll steel. Cold rolled has a lot of stress and it can move like crazy when machined, where as hot roll doesn't have the stress. Steel being malleable moves, glass being not shatters.
Tempered glass is a very useful thing. The desk I'm sitting at right now is made of it, as are car windows, patio doors, the big windows on buildings - anyplace where the sharp shards of broken glass would be dangerous.
To find out more about it, Google for "toughened glass" - it's the preferred name for glass treated in this way:
en.wikipedia.org/wiki/Toughened_glass
wolfgang schmittenhammer I may have to try that experiment, "Prince Rupert's droplets" and make a video.
Might be interesting to drill from each side and meet in the middle so as to get below the high stress zones on the outer surfaces when breakthrough happens..
Won't work ;) Trust me.
@centrospherecom There doesn't need to be a video of it because it's stupid, and it has no real point other then to show you that it breaks the glass lol.
@centrospherecom If you really want to see it through. Skip the video to 5:04 that's what it looks like when you try drill through tempered glass.
"Almost half way thru" That's the point. In the middle of the glass sheat is were the most tension is. Heck! You can even drill almost half-way with normal diamond bits without breaking it! But at close to center is what causes the "all hell broke loose" -situation! And that's what's causing it to explode. Codys lab even tried using acid to cut thru tempered class over several weeks and failed. Dunno if it's even possible to make hole to a tempered glass in any way? Interesting!
Once it's been tempered, you cannot drill a hole, but you can sand/grind away the edges of a tempered glass panel to a degree. Thanks for watching!
I have a challenge for you. Do u think u could ever drill common sense into a tempered woman? 🤣
Did you continue this experiment? were you ever successful? I felt like you should not have stopped and restarted - it looks like it nicked when you did that. I'm also thinking that, you should use the smallest bit possible. Once you are all the way through, you can grind it to be larger. If someone could successfully find a way to drill through tempered glass, my 9' x 4.5' large, foggy, half moon, tempered glass window could be evacuated, refilled with argon, and sealed.
Man... I was rooting for you! Even though I knew.
I tried. :-)
Nice video.
***** Thank You!
3500 psi in a scuba tank??? I had no idea they were pressurised to that extent!
Do you re-fill it yourself?
Bob Bailey No. I have it filled. Typically they are filled to 3,000 - 3,250psi, but people fill new tanks sometimes to as high as 3,500psi.
I just tried to drill my shower wall... it shattered but I probably got a third of the way using a Milwaukee drill and a bit at the local hardware store specifically for glass.
I know the bit you're talking about. It resembles an arrowhead.
DAMN IT...I WANT TO CUT TEMPERED! :D ...I have been working with glass for decades and I knew it's properties but was never fool hardy enough to attempt to cut it...Looks like nobody is successful. Maybe an ultra high speed wet saw with a oxyacetylene torch...:D Don't cool it, heat it...
You should use a high speed camera and catch that in slow motion.
I doubt that it had anything to do with the pressure you put. That isn't how it works. From my understanding, it works kinda on the same order of the prince Rupert's drop thing.
You always have good video s
4:55
Dentist flashback
Yes, not a pleasing sound. :-)
I think it would be better to place the wood directly under the point of the drill, so as to remove any pressure on the glass. otherwise good video on how brittle tempered glass really is. thanks
snaprollinpitts If the glass was thinner, and/or I was pushing down hard on the drill, then yes. There was little, if any flexing between the wood boards. The spacing between the boards was too close and the glass was too thick.
Thanks For Watching!
I wonder if adding something to dampen the vibration in the panel would help, maybe roll some plumbers putty out on the surface or set it down on a soft rubber mat. Another option might be to smooth the ball and just put some abrasive in the pocket?
I'm sure you can come up with a million different ideas too, just fun to speculate.
jcims I don't think there is any way to successfully drill a hole in tempered glass, but it certainly was fun trying, and I drilled a lot more than I ever imagined before it broke.
Thanks For Watching!
You can see that tension being released in slow motion in my other video.
Wasn’t pressure man. It was sonic vibrations from the drill along with constant air mixed with water making it really cold in that one spot along with the point of drill is impossible to keep same temp 100 thousands away from the drill point. If their was a way to use a thermal laser on drill point and 1 millimeter away from drill point and adjust air flow and water flow and water temp to match the entire plate and you need some type of damper to minimize vibrations
Vibration was definitely a factor.
The burr made it further than I thought it would.
boogeymanoneoneone I was pleasantly surprised also.
Don't think you would have been able to drill through, the stress caused by the tempering is what caused the break. Try heating the glass to untemper it before the next attempt.
ryan cler More than likely correct. The next time I have some scrap tempered glass laying around, I will try using a fine diamond burr using lighter pressure. Still very impressive to drill as deep as I did into that 3/16" glass. You won't see people drilling anywhere close to the depth I did in tempered glass.
Thanks For Watching
My tooth!
I thought that the way they drill tempered glass is with brass tubing and abrasives?
rstevewarmorycom I never heard of anyone successfully drilling tempered glass using that or any other method. If it is able to be done, then the dental drill using a medium diamond burr with very light pressure would be the best bet.
Sonic waves coming from the spinning bit causes the breakage.
Doug Smreker Makes sense. :-)
So after you raved on about your set up for half the video, we got to the point. No, you can't drill tempered glass. Thanks for demo anyway dude.
The setup was for my teeth, not the glass. LOL
What about making a ring of very sticky stuff like maybe contact cement to hold the tension of the glass out side of where you drill? Both sides of course The glass has tension on the surface: its the tension between the two opposing surfaces that make it strong and shatters the way it does. Like the cables on a suspension bridge.(I Think). I've been able to do something similar with a dremel but never all the way through.Only more shallow before mine broke..art piece trial.
what will happen if you touch the head of head drill
Not much, unless you press against the diamond burr or hold your finger there. Thanks for watching!
Dis dah budget dentist
What is this for
Asim Masoom What do you mean?
electronicsNmore I think he/she means what would be the use of drilling through a tempered glass panel....what are the applications. There are plenty if you could do it cleanly w larger holes... but even if you could get through....It likely wouldn't ever be more than a small hole.
dtfcd This video was nothing more than a test. If a precision instrument such as a dental drill cannot drill through tempered glass, then nothing will be able to do it. I was also showing viewers my homemade air/water supply system using a scuba tank.
Thank You!
Use trihawk talon bur instead
LOL. I guess you watched another video on YT where "Bullet Proof" glass is cut. He wasn't cutting glass, he was cutting "polycarbonate". Thanks for watching!
I am telling you to use trihawk talon bur on tempered glass instead of regular diamond bur , talon will cut it within seconds without shattering it
Wait No slomo of the glass shattering ? 😂
I had no slow mo camera. Big channels make lots of money, so they can afford high end slow mo cameras. If I received more support from viewers, I'd be able to spend a couple thousand on a good slow mo camera. Thanks for watching
You can still slow down the video a little bit with editing software.
psirvent8 I did that in my other tempered glass video. :-)
Делать мужику нечего
Спасибо за просмотр!
LOL
It was a fun attempt. :-)
