Cinder blocks are a type of block used in constructing the foundation of many homes. They come in various sizes, but are generally 8-by-8-by-16 inches. Oftentimes when you are installing cinder blocks, they must be cut to size to fit around corners and at the end of walls. There are numerous ways to cut cinder blocks, and one of those ways is with a small, portable circular saw called a Skilsaw, or skill saw. With the proper blade, it is perfect for cutting cinder blocks.

Things You'll Need

  • Tape measure
  • White chalk
  • Masonry blade
  • Rag
  • Safety goggles
  • Dust mask

Measure the area where the cut piece of cinder block will be installed. Record the measurement and transfer that same distance onto the cinder block you will be cutting. Mark the cut location with a piece of white chalk so the line is clearly visible.

Pull back the blade guard on the side of the saw and attach a masonry blade to the Skilsaw. Tighten it down by hand. Turn it clockwise until the blade is securely in place, and let the blade guard fall back over the blade.

Set the cinder block down on a flat surface, and line up the blade of the saw to the mark on the cinder block. Press the blade of the saw up against the mark on the block, and press down firmly.

Turn on the saw and cut carefully thorough the cinder block. Hold the block in place with your nondominant hand, and move the blade of the saw straight through the block until you reach the other end. Turn off the blade of the saw once the cut has been made.

Wipe off all dust from the cinder block with a clean rag, and measure the piece that was cut. Verify the proper size cut was made, and repeat the process for any other cuts that need to be made.

Tips & Warnings

  • Always wear safety goggles and a dust mask when cutting cinder block. The process will produce a lot of dust.
