Safe to drill? (5mm glass 3 holes external overflow)

[gblaszczuk]

I am building a 10 gallon shallow nano tank, setting it up peninsula style. I want to put the 800 modular marine external overflow box + a return line on the short side of the tank. This requires drilling 2 45mm holes (overflow) + 1 30mm hole (1/2 inch return bulkhead). The tank is an ada 60f (5mm non tempered glass).

I spaced the holes 1x diameter from the sides and almost 1x from the top (see picture).

Should I be concerned with 3 holes spaced apart like so on the short side of the tank (12"wx9.84"h)?
Also, since the glass is 5mm, is hanging an external overflow too much stress? I am planning on supporting the overflow box + adding supports for the plumbing so that most of the weight is not on the glass edge.

Thanks!

Most people will not comment on drilling glass. You can, however, with caution, don't want to crack the glass. I have always had a glass professional do the job.

Thanks!

If anyone looks at this post, I was able to drill the glass without any issues. I recommend taking your time and going extra slowly.

I plan on supporting the external overflow box with stand + supporting the overflow pvcs to not put too much strain on the glass.

Take your time, use a cordless drill, use a lot of water for lubrication …the sensitive part is at the end of the hole when your almost through…I’ve drilled glass but yes it’s always a risk. You can’t put a lot of pressure on it and you have to make sure you’re drilling straight. And use a very good glass cutting bit…don’t cheap out. Good luck…
