More info about what size circular saw to cut 4x4

If you need to cut a 4×4 post, then the ideal tool is a large 12” miter saw. This saw has the blade diameter needed to chop through a 4×4 in a single pass, so if this is an option for you it’s the way to go.

Standard circular saws with 7 ¼” blades can only cut 2 ½” deep, so making the cut in a single pass isn’t possible. “A miter saw isn’t always an option though; if you need to cut a 4×4 on the job while you’re installing fence posts then a circular saw is a better option, as it can cut through a 4×4 in 2 or 3 passes, and is far more portable than a 12” miter saw. Line up your saw with the cut line from step 1, slide the blade in the existing groove, and complete the second cut.

In this article, I’ll guide you on how to cut 4×4 lumber with ideal sized circular saw. For general infrequent work, you can use your usual circular saw and blade and make several passes.

The best way to cut a 4×4 post is by using a 12-inch miter saw, 10-inch radial arm saw, both of which can cut completely through a post in one pass, or a standard circular saw that can make precise cuts in two passes with the help of a simple jig. For a fence post or even a deck support post that’s going to rest on gravel and be supported by a cement base, an uneven end in which the cut is off by 1/8th of an inch won’t make much of a difference as that end will be buried in 2 or more feet of cement. Cut the first side, follow the cut line, rotate the board 180 degrees, and cut the second cut line completely through the post.

If your post is too thick to cut with one pass then you will need to mark all sides of your post and rotate the post making multiple cuts until your able to fully cut through the material.
