Avoid splintering hardwood table saw.

For a circ saw this means placing the good side down and on a table saw the good side up. A zero clearance insert fully supports the wood fibers right at the cut line which will dramatically improve your cut quality. A jigsaw works well especially for intricate cuts in doorways or around floor vents. If you have a circular saw with the shoe set to maximum depth you will get more splintering than if you set it so that it will just barely cut through the wood because the angle that the teeth come out of the wood is lower to the wood when you are working on the outside of the curve of the blade.

Some people even suggest raising your blade all the way up to avoid tear out. No matter what tool you re using the best way to reduce tearout is to surround the blade or bit with a zero clearance surface. This means that if you re going to avoid tearout and splintering you need to adjust how well the fibers are supported or how intense of an impact you make to the fibers. Always use an appropriate blade for plywood and be sure that it s sharp.

Always use a zero clearance insert. The chipping is most pronounced when you cut across the grain and can be severe enough to require filling if you cut carelessly. Every table saw has a throat plate that sits around the saw blade and it s main purpose is to support wood so small pieces of wood don t go into the hole around the blade.

The veneer on oak plywood is usually very thin around 1 32 to 1 16 inch and it s prone to chipping or splintering when you cut it with most wood saws such as a circular saw or table saw.

The thin layers of plywood can often splinter and chip when cut with a power saw resulting in an ugly edge that looks like this. We strongly advise you against doing so because you are increasing a risk of kick back and making even more damage to the plywood and yourself.
