Help with Drilling Acrylic Sump

[BC Mosaic]

Because it is brittle and so it tends to spider-web and at times even chip. Maybe it was just me and quite possibly just the wrong blade! LOL! However there is constant contact with a hole saw's teeth and so it scrapes/peels away, like a planer; less stress on the acrylic sheet. Just my 2 cents and experience.
I guess, upon reflection, I'm not that fond of hand held jig saws.

I'd have to second BC Mosaic's comments on the jigsaw. It probably works, but the back-and-forth motion pushes and pulls the acrylic, creating unnecessary stress on it. Anything that rotates should be better.

I drilled my sump with a hand drill and hole saw. Just don't put to much pressure let the drill do the work and it shouldn't splinter on ya
