I’ve found that square hole drill bits can vary significantly in price. While I don’t always opt for the cheapest option, I keep my budget in mind. It’s essential to balance quality and affordability. I’ve learned that investing a little more in a high-quality bit often pays off in the long run, as it tends to last longer and perform better.
