Plywood cutting circular saw blades, shop made woodworking tools - Test Out

We show you out seven best tips for making smoother, straighter and more accurate cuts on big sheets of plywood. Raise the blade height. Typically, to prevent kickback with power tools, you set the blade to exit the wood just at the gullets, the valleys between the teeth.
This way, all I have to do is ride the edge of the saw along the guide to get a straight cut. So for a circular saw and miter saw, make your cuts with the good face down; on the table saw, with the good face up. By raising the blade you can change the direction with which the teeth actually enter the wood, shifting from an angled cut to an almost perpendicular cut. Second, as you can see in the photo below, I also place the plywood on a sheet of 2″-thick, rigid foam insulation.


These blades will work for rough cuts in construction-grade soft lumber, but for working with hardwoods and sheet goods, you need to upgrade. Adding low-adhesion blue masking tape to both faces on the cut line holds the wood fibers in place while cutting plywood.
On a table saw, you can buy an aftermarket insert blank, or you can easily make one yourself. For the circular saw, attach a thin piece of luan or compressed hardboard to the shoe of your saw, then lower the blade to cut a zero-clearance slot.
So get some help: Ask a friend or family member to assist, or use a roller stand or sawhorse to keep things flat. For table and miter saws, invest in an 80 TPI plywood blade, one designed for cross (miter saw) or rip (table saw) cuts.
That way, you can focus on pushing the wood or saw at a consistent feed rate, getting a cleaner, straighter cut.


If possible, use a circular saw to break down large sheet goods into manageable pieces, and then focus on cutting the finished edge. Also, whenever you use a circular saw, set up a straight edge or fence to guide the foot of the saw.
