They do indeed really cut square holes. They're called mortising bits. Like the other commentor stated, they're basically a combination of a chisel and a drill. The drill does most of the work in waste removal while the square blades give you 90° corners.
One could also potentially consider a rotary broach to be a "square drill" (supposing that it is a square and not a hex or other shape).
Thanks for explaining better than I possibly could.
Nah. Don't sell yourself short. Your explanation is accurate and to the point.
Well thank you for the vote of confidence, but no, your explanation is much better; mine was basically a summary, while yours is in-depth
Due to how my brain works (ADHD), I specifically have trouble with being concise. So, despite what you may think, I find your accurate and concise explanation to be excellent.
Well fine then, let's both prefer each other's answer :P
Honestly, I am glad you liked my simplified explanation; I greatly appreciated your in-depth explanation.
Also, Lemmy is great, here we are arguing that the other guy's answer is better; on Reddit we'd be having the opposite argument
