Is it possible to cut 1/2" plywood without shredding it?


First of all I would use a decent corded saw. Most cordless saws don't have enough power. Second, use a straight edge and score the plywood on both sides with a utility knife. Third, buy a very good quality carbide finish blade.

Its hard to tell from that picture but it looks like you are cutting perpendicular to the grain, and it looks like the surface veneer is luan. You are probably using a 24 tooth carbide blade also.

1. Change to a plywood blade.

2. Put the finished side down when you cut. A circular saw cuts up through the material.

3. As Willie said, you score the surface where the blade comes up through with a razor knife and cut just to the right of the score line.
My dad taught me that one way back when when we had to trim doors down for the nut cases that put wall to wall carpet over their hardwood floors. Back when WTW was all the rage. It was a sales BS routine adopted by builders to get out of putting down hardwood.

Kind of like the rage about Stainless Steel Appliances, and granite is now. As my grandson says

"Granpa, why do they call it Stainless, when all it does is show Stains, like fingerprints? Why dont they call it stain-full Steel?

Kids a pisser. A correct pisser.

PS I did not know you were using a battery saw. A good corded saw is much better, as the others said. 7-1/4 inch Makita is good. High speed steel plywood blades for finish work. Notice I said blades, as in plural, as they don't last long.

A good sharp carbide blade made for crosscutting and an a/c powered saw will do it. It will have many teeth, at that size I believe around 40. If you want to get real fancy a triple grind blade (if they make them that size) will do wonders.

One option not mentioned is to perform a rough cut with a saw, then the finish edge with a router and straight edge. I have had good luck with this approach.

You also might find that making a few jigs like this will be of benefit.
I have an 8' one, a 4' one, and a 2' one. Mine are a little different in that I set up BOTH sides on mine... one side for a skill saw, and the other side for a router.

Finish side Up with a table saw, Down with a circular saw. I think you were confused. Dont worry, it gets worse.

Doesnt work if you need both sides finished. Doesnt matter anyway, i was planning to use it to make my doors and that isnt going to work. So, sorry to waste your time.
