I need to cut one 6" hole for a can light into a plaster ceiling and don't want to spend the money on a hole saw. What are my best options?
Although it's not the cheapest option, it's only $20. A jab saw may be half the price but with this drill bit you will make a precise circular cut. AND it's adjustable and allows you to cut anywhere from 1-3/4 to 7-7/8" circular holes. So it gives you a lot of versatility.
This one is on amazon but you can buy it online through the Home Depot website:

I'm glad you started this thread because I am going to buy one for myself.
