What does narrow kerf mean?
Just as low profile chain has shorter cutters than standard chain, narrow kerf chain has narrower cutters than standard chain. The result of using narrow kerf chain is a thinner, narrower cut. Because the cuts are thinner, narrow kerf chain ultimately removes less wood than standard chain when cutting.
How thick is a typical table saw blade?
A full kerf is 1/8″, whereas thin kerf is just 3/32″. As you can imagine, it takes less machinery muscle to force the thin kerf blade through solid wood than it does the full kerf. On long rips, for example, lower powered saws might bog down. So a thin kerf blade is actually easier on your saw motor and parts.
What is the kerf of a circular saw blade?
Kerf can be measured in inches, but for easy reference, anywhere between 1.5mm and 3mm is considered thin. Anything above that is thicker kerf, sometimes called a full kerf. If your saw blade is loose or unaligned, it will move or wobble.
How thick is a standard circular saw blade?
1/8 to 1/4 inchThe plate of a saw blade is often 1/8 to 1/4 inch thick. The thinner plate means that there is less sawdust and potentially less waste. However, thin blades, often called thin-kerf blades, are very sensitive to heating and wobbling, which in turn means non-straight (wavy or snaky) cuts.
What is saw kerf?
Simply put, the saw kerf is the thickness of the cut made by a blade. Or rather, it is the part of the board that turns into sawdust when you cut through it with a saw blade.

Why do woodworkers need kerf width?
Woodworkers pay attention to kerf width in order to maintain exact precision when cutting parts for furniture, cabinets, and other fine woodworking pieces. For projects where precise tolerances are critical, the 0.098 inches of a kerf width can matter when measuring and cutting parts. To a lesser degree, woodworkers are also concerned with the wasted wood that results from blades with thick kerfs. Over time, a substantial amount of expensive hardwood is turned to useless sawdust by saw blades, and the thinner the blade, the less wasted wood there will be.
Why does my saw blade wobble?
A saw blade that is out of alignment will wobble while it is cutting, and this can increase the width of the kerf by a notable amount. For efficiency of cutting and economical use of wood, always make sure your saw blades are properly aligned.
Do you put teeth on a wood saw blade?
Often the teeth are not added onto the blade but are integrally shaped into the metal of the blade itself. This makes for a very smooth cut and one that is economical since little wood is wasted through wide kerfs.
What is the kerf of a saw blade?
To put it simply, the kerf of a saw blade is the widest part of the blade. The widest part of the blade is at the teeth – they stick out slightly more than the rest of the saw blade. Kerf is the amount of material that is removed during a cut. That is always equal to the width of the blade.
Why use a thin kerf blade?
A thinner kerf cuts through material more efficiently than full kerf, and it uses less power to do so. If your saw is on the lower end of the power spectrum , it becomes beneficial to use a thin kerf blade. However, when using a low-powered saw and a full kerf blade, you can make the cut slower to compensate for the larger and heavier blade of a full kerf. But you risk burning the wood due to increased friction and longer time the blade is in contact with the workpiece.
What is the difference between a 10" saw blade and a 10" saw blade?

The saw blade didn’t just cut the bat in half- it removed all the wood in the path of the saw blade. The width of the material removed is called the kerf . Thin kerf blade on left, with full kerf blade on the right.
Why is a full kerf blade better than a high powered saw?
This makes it better suited for a high-powered saw. A full kerf blade will also be less affected by heat when making a cut. It can disperse heat more efficiently due of its thicker metal plate. The thicker plate makes it less likely to bend while passing through the material, decreasing the chances of blade deflection.
How thick is a full kerf blade?
It might not look like that much, but a full kerf blade is 33% thicker than a thin kerf. Keep in mind that there are no industry standards for thin kerf and full kerf. A thin kerf from one company could be almost as wide as a full kerf from another. But most major manufacturer’s follow 3/32″ for TK and 1/8″ for FK.
What is a kerf on a bat?
The kerf is the width of the saw blade and the amount of material removed during a cut. The saw blade removed 1/8 of an inch of wood when it was making the cut. Divide the 1/8″ in half to determine how much extra wood was removed each half of the bat, that is 1/16″ on each side.

Why Thin Kerf Blades?
So, with this risk from thinner kerf saw blades, why would any woodworker want to use them? The major reason for using thin kerf blades is to save materials. When one is working with exotic hardwoods, which can run as much as $60.00 per board foot, even 1/16” inch of wood is important to save. Every scrap is usable for something. Just multiply the thickness with the width and length of sheet and now look at the total amount of wood that’s saved. Next to the less material loss, benefits like competitive price, lightweight and possibility to mount them on every circular saw, no matter is it weaker or more powerful, make thin kerf saw blades a favorite choice among woodworkers.

How do carbide tipped circular saw blades work?
If you look at the construction of a carbide tipped circular saw blade, you will note that the blades teeth are welded onto the blade plate, and are thicker than it. In the case of high speed steel saw blades, the teeth are integral with the blade, although the kerf is still thicker than the thickness of the blade plate. This is caused by the teeth being “offset” from the blade. All that means is that they are bent slightly to the side, alternating sides from one tooth to the next. One more thing that can affect the saw kerf is the flatness of the blade. If you can imagine how a blade would look that is slightly warped. In that case, the teeth would not follow each other in the exact same line, but rather wobble back and forth a bit, much as a car tire that is mounted on a bent rim. This wobble would actually cause the blade to cut a wider kerf than the thickness of the teeth warrants.
Why is my circular saw blade not flat?
Since sheet metal is often rolled at the mill where it is forged, then unrolled and cut into sheets, before fabrication, it may not be totally flat. While your eye probably cannot see the amount of curve in the blade, it can still cause the saw kerf to be greater than the thickness of the blade and teeth warrant. Extremely high grade circular saw blades are made from steel that wasn’t rolled at the steel mill. This steel is much more costly than regular sheet steel, due to the increased labor involved in handling it in processing. However, a blade made with this type of steel will have no wobble, making for the smoothest possible cut.
What does it mean when a saw blade is bent?
All that means is that they are bent slightly to the side, alternating sides from one tooth to the next. One more thing that can affect the saw kerf is the flatness of the blade. If you can imagine how a blade would look that is slightly warped.
