Spark erosion is ideal for making square holes...... or any shape for that matter.

We bought two EDT (electro discharge texturing) machines for texturing mill rolls at the steel works. The consistency of the finish both in peak height average and peaks/cm was a step change improvement over the grit blasters they were supplementing. Grit breaks down and gives a finer finish as it is used. EDT has far superior repeatability. The only trouble was they took about an hour to texture a roll as opposed to 10 mins in the blaster.

I use wire EDM at all the time, makes fine knife through butter cuts through anything conductive (metal). Great for chopping stuff up.
