Saw cutting a Standard unit creates a smooth, straight surface.
Generally, you'll saw cut a Standard unit when a straight, smooth edge is required for a tight fit with the straight, machined edges of adjacent units.
Saw cuts are typically made using a gas-powered cut-off saw with a diamond blade. Always cut on a flat, stable surface.
Place the unit face toward you with the top side up. Make a straight cut 2 to 3 inches into the unit face. Starting saw cuts at the face ensures a clean line for the portion of the saw cut that will be visible. Then, saw cut the top of the unit, using successively deeper cuts. Flip the unit over and finish by cutting completely through the bottom of the unit.
