    i asume you have a portable airconditioner that has the tube you put in a small open window, but you don’t have a convinent small window. it would be easier to cut a hole in the wall and install a dryer vent ( like where the air comes out of your house from your clothes dryer ). I wouldn’t try to cut the glass it might even be tempered glass that can’t be cut without breaking the whole pane.

    its better to get someone to do it for you… or you could end up with something wrong and might have to buy a whole new window.

    This is no job for amateurs, have some one in the trade do it for you.

    They sell glass drill bits, just bought a set. Use lots of lube (cutting oil) and be gentle.

    trust me dont do this your self you might really hurt your self. if you what to do a project like this you should go to your local hard ware store. then they can come over and do the job for you. plus it does not cost as much as if you did it a lone.

    best of luck. ttyl 😀

    Don’t even try it. Call a glass company and have them view the window and explain if it can be cut down or needs to be replaced.

    Wouldn’t attempt this. The first thing you’d have to do is pull the glass from the frame and that’s a job depending on how super large the window is. What’s an AC tube? I’ve been in AC for decades, don’t know that term.

    ok

    dont buy a glass cutter- for a circle you will need a drill bit. (***NOTE- if your window is tempered glass, it will shatter. there should be a printed insignia saying it is tempered if so)
    Back to the drill bit. Yes, cutting oil will work, it needs to be wet and cooled the entire time, circulating water is best. Its really tricky. If someone came to me at my store I would recommend they drill a hole in the window sill, the wooden frame of the window. The hole in the large window will make the window unstable and more likely to break. And then you will have to replace the whole window. With a hole in the wood at least you cat wood putty it back when you need, or repair a number of other ways. I get what you are trying to do – but I would have to advise against it.

How to cut glass?

what oil should I use to score glass and cut

    On very large sheets of glass, they some times use oil to coat the cut marks, but, its a thin oil of some sort, and they still “snap it”…If your cutting stained glass, none should be needed…

    Oil is really used to keep the glass down, (glass dust), so that it doesnt fly everywhere and get into things…(worse than fiberglass insulation)…

    Also, its used in “real old glass” that has ‘dried out’ a lot, and needs to be moistened…

    I wish you well..

    I’ve never used oil, I just score and snap.

    try a canola oil- they are all basically the same

    No oil needed, when you do use oil it makes it hard to see the line you have scribed

    WD40 or 3-IN-1 Oil will work while cutting glass. Remember to dip your glass cutter each time you go to make the cut as this will help aid in reducing splintering of the surface you are cutting. If you do not oil the surface when you scribe the surface of the glass it will cause the surface of the glass to make little splinters on the cut side and when you snap the glass off you will have what looks like a very jagged edge. The oil aids in the prevention of the jagged edge.

    It is a good idea to use oil, in fact you can get glass cutters that have their own reservoir for oil in the handle. Any light oil or white spirit will do.
    When you have scored a line on the surface tap the glass gently underneath the line of cut and it will break along that line.
    You can do straight or curved lines by this method.

    I’ve never used oil. Score with the cutting wheel, then crack across a slightly lower surface.

    use a glass cutter and a straight edge.
