Cutting a hole into glass 

Here's a tip from an old glazier, replace your safety circle with a safety triangle and it will all simply fall out, this will eliminate the need or risk of having to break out the second circle and it's quicker.

Clear and simple and quick. Thanks. Fingers crossed!

That was awesome 👌 keep it up, very professional No on going talk about this n that, straight to the point easy to understand and explain why n what your doing a great presentation

i wondered about this, looked impossible for a while, but perfect in end!

Thank you very much for this easy method.

Thank you!

Thank you Paul

Thank you for sharing I've never seen it done like that before

Hi Paul, thank you for this video, could a circle be extended to a square cut out

Great video. I cut a cat flap into a old patio door today. Everything appeared to be going ok until I discovered it wasn't a single pane of glass, it was two panes with plastic sandwiched between them. It isn't pretty under there and took a couple of hours but I managed to chip it away to the outer circle and the flap covered it all up. Mum was happy and will never know but OMG was it a messy ball ache - be careful out there people.

Great video without any nonsense trying to sale you specialised tool and lubricant, Well done one of the best glass cutting video on youtube, Thank you.

I have an old aquarium that is going to now be a vivarium. The tank is 5 foot long. The glass is 12mm thick. I want to cut out a 2 foot x 10 inch long rectangle, down from the top - so I only have to make 3 cuts, the 2 foot along the bottom of the rectangle and the 2 sides @ 10 inches. I have various sized glass cutting bits. I have a glass scorer. Would I be able to grind 2 holes, 10 inches from the top and 2 foot apart, then score between the holes, then score from the holes up to the top and then just tap it out? Hope that makes sense. Admittedly, there's possibly some wishful thinking going on. Thank you. Andrew

Very Good work..!

In the movies it seems faster and quieter lol

Thanks, needed to know how to do this. What sort of sand paper would you recommend to soften the edges so they don't cut something passing through?

A question: can you cut the grounded glass in a similar way? Thanks

Could you do the same but Square hole in 30mm non tempered glass??

What would happen if you cut the glass twice? Or even three or four times to deepen the score mark?

Very helpful, thank you!

Hi Daud, I think you would struggle to do this in 12 mm glass, it is possible but I have never done it in glass that thick, if you are going to cut 12 mm glass just make sure it is not toughened as this cannot be cut.

Do you think this will work on 75 year old glass window panes?

Can you do the same thing cutting a circle in a glass door?

Thank you! Upon watching your video, I assume that you need to "tap" the scored glass circle on the underside of the glass. Meaning on the opposite side that you scored with the glass cutter (like I see in the video). I am cutting a circle on one pane of a double-pane window glass and the underside is not accessible. Does this explain why it doesn't work when I tap the scored side? Best Regards, p.s. It might explain some of the questions you were previously getting.?.? The circle is my first step at breaking and removing the glazed in defective pane. IT IS NOT AN IGU! Tnx!

Great vid. If I wanted to put a window inside my current fixed van windows.. meaning a window within a window! how could that be done? Any ideas?

nice and clean

Is this tempered glass? Will this work for window glass? How thick is the maximum that we are able to cut?

Well done.

You need links to tools supplies who will pay you nice commision, could be Amazon. Thansk so much for the advice.

Hello, question, what if you want to use the inside of the circle? Meaning, save center and get rid of the loop? And to further the complexity make all this in a glass the size of a watch

Perhaps safety goggles come in handy

good works nice explanation for glass hole cutting

That was gold

Thank you for this... and help me pray today.. I bought a HUGE glass cabinet to build a paludarium.. 140cmx120cmx50.. And i need to cut a 15cm hole into the side to be able to reach the electronics after it is set up... I might have taken a little to large of a bite to chew because i cant lay it flat to cut a hole into it.. but ok,, it either works or it cracks and the whole thing will have to go to the scrapyard haha.. Thank you for this video very clear explenation, ill try and go about it like you showd,, thanks again

Very convenient. Now you can try with Cloud Laser equipment. )))

What if I wanted the circle, not the outside?

And what type of adhesive is best for bonding glass?

Will there be any issue if i do the same technique with squares?

Cool

If while opening the cut, your cut shoots out toward the outer circle, is there any way to continue? I still have about 1/3 of my circle to open and can't seem to get it back on track.

Us there a way ro smooth the edge aftee so no one gets cut on it?

I have cut a hole in 6.4 laminated and old quarter plate glass

Unclear which side to tap.

Thanks sir

in case of double glazing how to make the circular hole?

thanks for the answer, yet I saw this video what you think

Is this possible with 12mm glass?

Can you do this without removing the glass from the window?

That was actually very informative. But man, maybe some glasses of any kind? I’m still wrecking my feet on old ass glass.

Hi, Good job and your very skilled, one thing you really should be wearing safety glasses, i know this having been a glazier for many years.

Tried this on Victorian flow glass .. just kept cracking right through the circular cut

Need to dip your cutter in that sounds terrible but nice job

Zo hoort het

Not bad please excuse me. I have been cutting many years. From me you need to change that wheel in circle Cutter, you need to apply less pressure on the cut, you need to use cutting oil, you need to use a oil filled cutter again less pressure, for me I use the rubgy ball saftey lines technique, I turn the glass and use pressure to open the cut rather then hitting the hole open like that,, the Chris Cross lines must be with oil, as before a new cutter will open cut lines easyier and thus glass with fall with ease and put less pressure on vent hole, for me the rugby ball lines act as safety lines, tap the middle and work middle first so not to have shells. Much appreciated for video. You got it out, 😉

Put some safety glasses on, you must not value your eyes!

Messy shit cutting
