Best Jigsaw Blades (and How to Choose Them)

I have spent two decades cutting through everything from 2x4 pine to thick sheet metal on job sites across Ohio. Most guys ruin their projects because they use the wrong blade for the material. A cheap blade will wander, burn your wood, or snap halfway through a cut. You need to match the steel and the teeth to your specific task to get a clean edge.

Shank types

You must check your jigsaw before buying any blades. Most modern tools use T-shanks. These have a narrow neck that allows them to sit closer to the machine's base plate for better control.

U-shanks are older. They are wider at the top and fit mostly in vintage machines from the late 1990s. If you try to force a U-shank into a T-shank saw, you will break your tool or the blade immediately. Always verify your shank type first.

Blade materials

Material choice determines how long a blade lasts before it gets dull. High Carbon Steel (HCS) is cheap and works well for soft woods like pine or cedar. These blades do not last long because they lack the hardness to handle tough fibers or metals.

High Speed Steel (HSS) offers more durability than HCS. You will find these used frequently when cutting thin sheet metal or plastics. They hold an edge longer, but they can still struggle with heavy-duty demolition work.

Bi-metal blades are my standard for most jobs. These consist of a high-speed steel edge bonded to a spring steel back, which provides the flexibility needed to prevent snapping under pressure. Use these when you want a blade that survives more than one afternoon of hard labor.

Carbide-grit blades are different. They do not have teeth; instead, they use tiny particles of carbide glued to the metal surface. These are the only real option for cutting ceramic tile or thin glass without shattering the material.

Teeth & TPI

TPI stands for Teeth Per Inch. This number tells you how many individual cutting points sit along one inch of the blade length. High TPI means small, closely spaced teeth that create a smooth, clean finish on delicate surfaces.

Low TPI means large, aggressive teeth designed to tear through material quickly. If you use high TPI on thick hardwood, the blade will overheat and burn the wood because it cannot clear the sawdust fast enough. Match your TPI to your speed requirements.

Tooth set also matters for the cut width. A wide tooth set creates a larger kerf, which removes more material and allows for faster cutting in heavy timber. Fine teeth create a narrow kerf that is better for precision work on furniture components.

If you are unsure about which specific blade matches your current project, use our selector tool at /tools/blade-finder/. It simplifies the decision process by filtering through technical specs.

Frequently asked questions

Why is my blade burning the wood during a cut?

This usually happens because your TPI is too high or your saw speed is too fast. When small teeth struggle to clear sawdust from a deep groove, friction builds up and turns the wood black. Slow down your stroke or switch to a lower TPI blade for thicker stock.

Can I use a wood blade to cut metal?

Do not do this. A wood blade has large teeth that will catch on the metal and likely snap the blade or kick the saw back at your face. Metal requires HSS or bi-metal blades with much higher TPI counts to slice through the material safely.

How do I know when a blade is officially dead?

Look for rounded tooth tips or visible discoloration from heat. If you notice the saw struggling to maintain its speed or if the cut starts wandering off your line, the edge is gone. Replace it immediately to avoid ruining your workpiece.
