Sometimes you got a project where you have to drill a hole and it does not have to be on intermediate size. In other words, it is a hole that is bigger than what a typical drill beat will drill, but it is too small for you to use a jig saw to get a nice hole. So what do you do? I will tell you what I like to use is a hole saw. They are made for that. These are special saws that come in sizes anywhere from a half inch all the way up to two and a quarter inches and they drill a perfectly round hole in wood, metal, or plastic.

Here is an old fashion hole saw and this particular one would fit in into your drill but here. It has a set screw that allows you to change out this bit. But the trouble is this particular set screw would loosen up as you are working with the tool and everything will get jammed up. You would have a nightmare in your hands trying to drill this hole.

Now, we have new hole saws that come with an interchangeable drill jack that allows you to go ahead and put the hole saws right on to the tool and snap them into place. And when you are finished with that particular size, you just snap it off and put on any other size that you need to make the drill work.

Ah, perfectly shaped holes that is the object of this drill.
