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 –
