As in the other comments, Slow the speed down but also take short cuts with light pressure, That is, Taking the hole saw or drill bit out frequently to eject the chips, This helps prevent excess heat build up, This is very important when drilling thick plastics to prevent the excess heat build up which can bog down the drill, Ruin your work piece, Overheat the drill bit which will draw the temper and ruin the bit, A drill press gives you much better control

Spray spam non-stick cooking spray on the area of the cutting and this will reduce cleanups. The low temp oil will reduce heat buildup at the cutting site.

Hope this will help

You are absolutely correct, Slowing the speed down and using a drill press along with the wood backing, The wood prevents the drill bit grabbing the acrylic which can bust it very easily when the drill bit is almost through, One key thing is, Taking short cuts, Then backing out the bit very frequently to eject the chips which leads a lot to overheating, When the bit is hot to the touch, Let it cool before continuing, This also helps prevent melted acrylic

I'm super worried about ruining my big expensive piece of acrylic.

whats wrong here is the speed is far too high. The drill should be at a slow speed and slow feed down, much better to use a drill press. the timber backing is recommended. The extruded acrylic has more in built stress than cast acrylic but don 't think it any softer. I have been in plastic industry 20 years and drilled lots holes in acrylic. A lot of questionable advice about.

You can minimize the melted plastic with lower speeds

is it cool to use an HSS hole saw drill bit for metal?

The melted acrylic is avoidable. You can avoid the melted acrylic by slowing down the drill and going down slow. I just drilled acrylic for the first time yesterday and it's something my dad taught me when using drills on heat sensitive material. Like someone said somewhere on here common sense and safety will take you a long way.

Did you just drill your counter top and not blink an eye? Thanks for the tip.

Would suggest using a" variable speed drill" and slowing the speed down, this will prevent the hole saw from melting it's way thru the plastic.

does it crack if you apply too much pressure?

What about just a plastic container? 🤔
