1.Avoid Cross Cutting Plywood tends to chip the most when cut across its width (grain). Cutting along the length of the wood will help to reduce chipping.
2.Use the Right Blade Special blades are manufactured for different cutting jobs. The number of teeth, width, angle, and rake of the blade all impact the cut. Choose a blade that best matches your specific cutting situation.
3.Circular Saw cut with the best face down.
4.Table Saw cut with the best face up.
5.Score the Cut First Run the plywood through the saw removing only a minimal amount of wood. The next cut will leave a cleaner cut.
6.Masking Tape Put masking tape over the cut line to help keep the fibers on the edge from pulling up.
7.Backing Panel Attach a backing panel with strong double stick tape. The backer board will take the brunt of the damage.
8.Use a Router A router fitted with a straight bit will cut a clean line. A pilot bit and straight edge will help provide a clean line.
9.Score with a Utility Knife Score the cut line with a utility knife.
10.Buy a Panel Scoring Setup Some saws can be fitted with a plywood panel scoring setup and are ideal if you have to cut a lot of plywood. The setup consists of a smaller blade that scores the surface of the plywood before it reaches the cutter.
