Table Saw Blades: What You Actually Need to Know

Table saw blades have gotten complicated with all the marketing claims and tooth configurations flying around. As someone who’s swapped more blades than I’d like to admit — and ruined a few boards learning the hard way — I learned everything there is to know about picking the right one. Today, I will share it all with you.

Types of Table Saw Blades

There are different blades for different jobs, and using the wrong one is a fast way to get ugly cuts or burn marks. Here’s the breakdown:

Ripping Blades

These cut along the grain. They’ve got fewer teeth — usually 24 to 30 — with big gullets between them that clear waste quickly. The cuts are rougher, but that’s fine because you’re just sizing stock. I keep a dedicated rip blade on my saw probably 40% of the time. If you’re breaking down rough lumber regularly, this is your workhorse.

Crosscut Blades

Going across the grain? You want more teeth. Like, 60 to 80. All those extra teeth mean cleaner cuts with way less splintering. I switch to my crosscut blade whenever I’m doing joinery or finish work. The difference between a rip blade crosscut and a proper crosscut blade is night and day — trust me, I tried to cheat and learned that lesson on a piece of walnut I’d been saving.

Combination Blades

Probably should have led with this section, honestly. If you can only own one blade, make it a combo. These have around 40 to 50 teeth and handle both ripping and crosscutting reasonably well. Not the best at either, but good enough for most hobbyist work. I ran a combo blade exclusively for my first two years of woodworking and it was fine.

Dado Blades

These cut wide grooves and channels for joinery. You’ve got two options: stacked dado sets (multiple blades and spacers you configure for width) or wobble blades (a single blade that tilts). I strongly prefer stacked dados — they give cleaner flat-bottom cuts. Wobble blades leave a slightly curved bottom that drives me nuts. If your saw accepts dado stacks, go that route.

What the Blade’s Made Of

The material matters more than most people realize.

High-Speed Steel (HSS) Blades

These are the cheap ones. They’ll work for light duty stuff and softwoods, but they dull fast. I went through three HSS blades in my first year before switching to carbide and never looked back. If you’re on a tight budget and cutting pine, they’ll get you started. Just don’t expect them to last.

Carbide Tipped Blades

This is what you want. Tungsten carbide teeth stay sharp dramatically longer than HSS. The cuts are cleaner. The blade lasts longer. Yes, they cost more upfront, but you’ll spend less overall because you’re not constantly replacing dull blades. Every professional I know runs carbide tips exclusively.

Coatings

Some blades come with coatings — Teflon or similar — that reduce friction and heat. They also cut down on resin buildup. If you’re cutting a lot of plywood or anything pitchy like pine, a coated blade makes a noticeable difference. Less burning, less cleaning. Worth the small premium if you can find it.

Features That Actually Matter

Tooth Count

Simple rule: fewer teeth = faster, rougher cuts. More teeth = slower, smoother cuts. Match the tooth count to what you’re doing. Ripping hardwood? Low count. Crosscutting for a visible joint? High count. It’s really that straightforward.

Hook Angle

This one trips people up. A positive hook angle means the teeth lean forward — they grab the wood and pull it in. Good for ripping. A negative hook angle pushes material away from the blade, which reduces tear-out. I use negative hook on my crosscut blade for plywood, and the difference in edge quality is dramatic.

Kerf

Kerf is how wide the blade cuts. Thin kerf blades waste less wood and need less power from your saw. They’re great for underpowered contractor saws and for getting the most out of expensive lumber. The tradeoff is they can flex a bit, so you need to make sure your fence and setup are dialed in. Full kerf blades are stiffer and more forgiving of sloppy technique.

Keeping Your Blades in Shape

Clean Them

Pitch and resin build up on teeth and reduce cutting performance. I clean my blades every couple months with a blade cleaning solution — you can also use Simple Green or oven cleaner in a pinch. Soak, scrub with an old toothbrush, rinse. Takes ten minutes and makes a huge difference.

Sharpen Them

Dull blades burn wood, strain your motor, and produce rough cuts. I send mine out for professional sharpening once a year, or sooner if I notice burn marks. A good carbide blade can be resharpened several times before it needs replacing. Way cheaper than buying new.

Store Them Right

Don’t just toss blades in a drawer where they’ll bang against each other. That chips the carbide tips. I keep mine in the cardboard sleeves they came in, hanging on a wall rack. Some folks make dedicated blade racks — whatever works, just keep them separated and dry.

Safety Stuff

Wear your safety glasses. Wear hearing protection. Use a blade guard and riving knife — I know half of you have those sitting in a corner of your shop, but they prevent kickback and they work. Check your blade for cracks or missing teeth before each use. A damaged blade is a dangerous blade.

Matching Blade to Material

Softwoods and Hardwoods

Ripping blade for sizing, crosscut blade for joinery and finish cuts. That’s what makes blade selection endearing to us woodworkers — once you nail the right blade for the right job, the results speak for themselves.

Plywood and MDF

High tooth count, negative hook angle. These sheet goods chip and splinter at the slightest provocation. A good 80-tooth blade with negative hook will give you clean edges on both sides of the cut. Worth having a dedicated blade if you work with sheet goods often.

Plastics and Metals

Specialty blades exist for these. Different tooth geometries, different materials. Don’t try to cut aluminum with your wood crosscut blade — I’ve seen people try and it doesn’t end well. Match the blade to the material, always.

The right blade turns a table saw from a rough tool into a precision instrument. I’ve been at this long enough to know that blade choice accounts for probably 70% of cut quality. Spend the time to pick the right one and keep it sharp, and your work will show it.
