How to Cut Concrete Fence Posts
- 1). Measure the desired length of the concrete fence post and mark the cut point on the post, and then use a hand square to extend the cut line to all four sides of the post. For concrete fence posts with a prefinished end (domed, beveled and so forth), be certain to mark and cut the bottom end of the post to retain a "finished" top.
- 2). Set the depth of cut to 1 inch on a circular saw equipped with a carborundum or masonry saw blade. Cutting the concrete fence post in 1-inch depth increments minimizes stress on the circular saw's motor.
- 3). Start the initial cut from either side of the concrete fence post and slowly move the saw through the full cut.
- 4). Rotate the concrete fence post 90 degrees and repeat Step 3 to cut the side.
- 5). Repeat Steps 3 and 4 to complete a cut on each side of the concrete fence post. A 1-inch-deep cut should now be completed on all four sides of the post.
- 6). Set the depth of cut on the circular saw to 2 inches and repeat Steps 3 and 4. At this depth of cut, the steel reinforcing bar(s) at the center of the post will be cut as well.
- 7). Repeat Steps 2 through 4 for concrete fence posts larger than 4 inches square until the cut has been completed.
