What kind of drill bit....

[EllieSuz]

I'm not big on DIY stuff, but I want to drill a hole in one of the baffles in my sump so I can keep the skimmer pump in a different compartment than my Chaeto. Hubby suggested this cone shaped bit and it just didn't look right. What kind of drill bit should we use on a thin piece of acrylic? Thanks.

use a diomand hole cutter with a guide bit. i used diomand hole saws to cut my rubermade sump already

If its just acrylic I've drilled holes before with just a regular hole saw. The biggest thing is keeping it cool so it doesn't melt the acrylic .

The step bit your hubby suggested will work very well to be honest.

I second the step drill bit if it is the right size.

Your husband is recommending a uni-bit. For this application, it's basically the same thing at a regular drill bit. If you use a hole saw, be it diamond coated or regular wood teeth style, have the hubby pour water on the cut as you're drilling. This does wonders to prevent melting. Goes from melting so bad it's not worth doing... to zero melting what-so-ever.
