You can pick a saw blade for plywood, hardwood and softwood by matching the tooth count to the material and the job. For plywood on a table saw, use a higher tooth count, since more teeth give a finer, cleaner edge. Cutting plywood on a traditional cabinet saw is best done with an 80-tooth blade [1].
A sharp, clean general-purpose or combination blade will cut hardwood, softwood and plywood about equally well [2]. If you cut a mix of materials, that makes one sharp blade a reasonable first buy.
Matching the blade to the job matters more than the brand on the package. A well-matched blade from a smaller maker usually serves you better than a premium blade meant for a different material. The steps below walk you through choosing by material.
How do plywood, hardwood and softwood cut differently?
Plywood, hardwood and softwood each reward a different blade, so start with the material you cut most. Each one fails in its own way when the blade is wrong, and knowing those failures tells you what to look for.
Plywood
Plywood is built from thin veneer layers held together with glue. Those thin layers are what chip when the teeth are coarse, leaving ragged edges on the face of your sheet. Work with a finer, sharp blade and let it cut at its own pace. Pushing the sheet hard is the fastest way to chip the veneer.
Hardwood
Hardwood is dense, so it puts more load on the blade than softer wood does. A dull or aggressive blade has to work harder, and the cut can slow down or scorch. If you feel the saw bog down partway through a board, stop and check whether the blade needs sharpening or a different grind.
One woodworker who uses a triple-chip grind for plywood notes that it works ok in solid wood. For a hardwood project, that is a workable fallback, but it is not the grind to pick first.
Softwood
Softwood cuts easily, which tempts you to rush. The risk is tear-out, where the wood splinters on the exit side of the cut. A grind that is wrong for the job makes this worse, even though the wood itself is forgiving.
When you cut softwood, slow down near the end of the cut. Support the offcut so it does not drop and pull the edge apart. The edge will look cleaner, and you will avoid sanding out damage you could have prevented.
What steps should you follow to choose the blade?
Choose the blade by what you are cutting. Plywood needs the most teeth, and solid wood can use a general-purpose blade. Work through these three steps in order.
Plywood on a table saw: use an 80-tooth blade. Cutting plywood on a traditional cabinet saw is best done with an 80-tooth blade [1]. Use it for every rip and crosscut, including the short pieces you cut from the end of a sheet. Those small pieces show chipping just as clearly as the long edges do, so keep the same blade on the saw for the whole job.
Want smoother cuts with less tear-out? Move up to a 40-tooth blade. Tear-out is splintering where the blade exits the wood. For smoother cuts with less tear-out, move up to a 40-tooth blade [3]. If you are cutting a full sheet, make a test cut on a scrap piece first so you can see the exit side before you commit to the whole sheet.
Cross-cutting or solid wood: use a 40- to 50-tooth general-purpose blade. You can use a 40-tooth to 50-tooth general purpose blade as well [4]. Pick the 50-tooth version when you want a slightly finer cut, and the 40-tooth version when you need to move faster through thick stock. This is the blade most people keep on the saw for framing, shelving and other solid-wood work.
Before you change the blade, unplug the saw. Keep the blade guard in place while you cut, and put it back on after every blade change.
Can one blade handle all three materials?
Yes. A sharp general-purpose or combination blade can cut plywood, hardwood and softwood, and it cuts all three about equally well [2]. If you have one saw and work on a mix of projects, this is the simplest choice, because you don’t have to swap blades between jobs.
A combination blade is built to rip along the grain and crosscut across it. That mix is why it suits a shop that builds a little of everything. A weekend deck repair one day and a plywood shelf unit the next can both run on one good blade.
Specialty grinds change the picture. A 40-tooth blade with a triple-chip grind gives the cleanest cuts in plywood [5]. In solid wood, the same grind works only okay [5].
That difference matters most when one material dominates your work. A cabinet shop that breaks down sheet goods all week will get better plywood edges from a triple-chip blade. Someone who builds a solid-wood bench or cuts dimensional lumber for framing will be happier with a blade set for that work.
Matching the blade to your main cut
Think of the blade as a tool for your most common cut, not a single answer for every job. Count how many hours a month you spend on each material. The material that takes most of your time should guide the purchase.
If you cut mostly one material, buy a blade set for that material. A plywood-heavy shop gets more value from a plywood-focused blade, while a shop that rarely touches sheet goods can stay with a general-purpose blade. A blade that matches your main job will do more for your cuts than a premium blade meant for something you rarely cut.
What causes tear-out, and how can you reduce it?
Tear-out is splintering at the exit side of the cut, the face where the teeth leave the wood. On plywood it shows up as small chips and broken veneer along the edge, and it can make a straight cut look ragged.
It happens because the teeth lift the thin top veneer instead of slicing through it. Plywood is prone to this because its face veneer is thin and its glue layers are brittle. A coarse blade and a dull blade both make it worse, because the teeth tear the fibers instead of cutting them.
Choose a blade with more teeth
A blade with more teeth takes smaller bites, so each tooth cuts the veneer cleanly rather than lifting it. When you move from a coarse blade to one with a higher tooth count, the plywood edge usually looks smoother.
The teeth also need to stay sharp. A sharp blade slices, while a dull one crushes and pulls. If the edge starts to look fuzzy, check the blade before you blame the saw.
Add a zero-clearance base
A zero-clearance base on the circular saw gives even less tear-out [3]. The base is a plate with a slot cut to the blade’s width, so there is almost no gap for the veneer to drop into as the blade exits.
The wood also stays flat against the base right at the cut. That support holds the fibers in place as the teeth leave, which is where the tear-out starts.
Here is a sequence for a plywood cut:
Fit the higher-tooth blade and make sure it is sharp.
Attach the zero-clearance base before you cut.
Lay the good face of the plywood down, so any tear-out lands on the side you will not see.
Push through in one smooth pass at a steady feed rate.
The blade handles the teeth, and the base handles the wood at the cut. Used together, they give the cleanest plywood edges.
Which blade mistakes cause poor cuts?
Three blade mistakes cause most poor cuts: a coarse blade on plywood, a dull blade on hardwood, and buying by tooth count alone. Each one is easy to avoid once you know what to look for.
Using a coarse blade on plywood
A blade with fewer teeth takes bigger bites. On plywood, those bites tear through the thin face veneer and the glue layers, leaving chipped edges along the cut. Plywood’s thin layers are what break, so the teeth need to be small enough to slice them cleanly. Cutting plywood on a traditional cabinet saw is best done with an 80-tooth blade [1]. Switch to that blade before the first cut on a sheet you cannot replace, because a chipped edge cannot be undone.
Using a dull blade on hardwood
Hardwood is dense, so a dull blade has to push hard to get through it. You will see dark burn marks on the cut face, and the feed will slow or stall partway down the board. Forcing the cut makes it worse, since the blade heats up and the wood tears more. Sharpen or replace the blade before a hardwood project, and feed the board at a steady pace.
Using a blade chosen by tooth count alone
A higher tooth count sounds like a better blade, but the number alone does not tell you how the blade will perform. A sharp, clean general-purpose or combination blade will cut hardwoods, softwoods, plywood, MDF and hardboard about equally well [2]. A sharp blade with fewer teeth can therefore do more for your project than a dull blade with many more.
Tooth count matters most when you cut plywood, where a finer blade gives cleaner edges. For solid wood, sharpness and the blade’s general-purpose design do most of the work. Look at what the blade is designed to cut before you look at the tooth count, or you may end up with a blade that suits one material and performs poorly on the rest.
What is the simplest way to decide?
For plywood, an 80-tooth blade gives the cleanest cut. [1] For hardwood and softwood, a 40- to 50-tooth general-purpose blade covers most jobs. [4] If you cut both plywood and solid wood, keep two blades on hand and swap them as needed.
Whichever blade you pick, keep it sharp. A dull blade hurts every material, so sharpen or replace it before it starts burning or tearing the wood. Your next step is simple: look at the material you cut most often, choose the matching blade, and make a test cut on scrap before you start the real project.
