will we need a punch to make the holes?

I could not force the rivets through the cardboard on their own, but I was using 2-3 layers of cardboard. Instead, I used a large nail or even just a screwdriver.

No, it is not a very practical hole punch. I really wanted to like it but I got this one instead...Rapesco 6 Hole Diary 66-P Adjustable Punch, 8 Sheet Capacity, Black (PF66P0B1)

There would be no need to do that since they thought ahead and have slotted holes all the way across to accommodate that action. If you really wanted to and had a very good drill or drill press you could put a hole though to answer your question.

No, but you could easily drill holes if needed. The material isn't too hard.

Yes a self-centering bit would be helpful. At the very least center punch the hole to be drilled.

You would need to predrill holes, but I don't see why it wouldn't work if you did that.

It is made of a plastic material, I think it would be pretty easy to cut and/or punch holes in it.

You can also screw the bases down with two small screws in addition to the adhesive strips. Already pre hole punched.

Yes, but it would take quite awhile to do so. I'd use a sander or a band saw to do most of the work first.

Yes. Some of the holes were not completely removed by the hole punch machine, but they were pretty easy to remove to allow for drainage.

Hi Cheery Girl, Yes, you will have to drill a hole unless you want to sacrifice say a hand sprayer using a previously drilled hole.

I'm not totally sure what you mean by punched. If you mean like a small hole punch for threading something through then the answer is no.

The holes are round but I would advise not ordering this punch. I have found that I cannot press hard enough to punch through a leather belt without first starting the hole with a drill or something and just using the punch to clean up the hole.

Yes, but a hole would need to be drilled through first. You would need a drill bit 1/16 or less. Need to get behind the lathe or mesh.

There's perforated holes that can be punched out as needed. I've just been punching them out with my fingers as I fill the shelves.

Don't know why you would want to use a punch--the material is too thick. Very easy to drill holes through the bottom, though. Maybe 3/8" for your purposes.

The directions said to "tap lightly" to punch out the hole. We had to get rather forceful with it. I believe we ended up using a chisel. Don't be discouraged, the sink is awesome and well worth the effort.
