What is a Kerf? “Kerf” is the width of the blade’s tooth tip or the breadth of the slot which the circular saw blade cuts in the material. It is also the widest point on the blade and hence thicker than the blade plate or body. This thickness is what decides your blade’s cost and its cutting capacity.
We bring you the ultimate guide on how thick a circular saw blade is to clarify your doubts and help you achieve accurate cuts. “Kerf” is the width of the blade’s tooth tip or the breadth of the slot which the circular saw blade cuts in the material. When the saw blade teeth are 1/32 inches wide, the circular saw blade is known to have a thicker kerf.
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. Thin kerf blades will generally be 25% thinner, creating a cut of 0.091″ or about 3/32″. The thinnest kerf circular saw blades currently made are 0.059″ thick.
A full kerf saw blade is a saw blade with 1/8 inch wide carbide teeth, so it is about 1/32 inch thicker than the thin kerf blade. Because thin kerf blades are less wasteful, it leads to greater material and cost savings. If you are unsure if full kerf or thin kerf blades are right for you, feel free to reach out to Luxite Saw.
The term is also sometimes used to describe the thickness of the blade itself; for example, you may see the packaging of a circular saw blade or table saw blade listing its kerf width. One manufacturer offers a standard crosscut table saw blade with a kerf of 0.098 inches and a fine-cut blade with a kerf width of 0.087 inches. The kerf is determined by the width of the blade itself, by the “Set” of the teeth, and by the wobble of the blade.
A simple beginner-friendly explanation of what is saw kerf and why you need to account for it to get accurate cuts. You CANNOT make accurate cuts in boards on ANY saw without understanding the concept of the kerf. Making accurate cuts while taking saw kerf into account is very straightforward and needs attention to one simple factor – alignment of the lad with the cut line.

What is considered thin kerf?
Kerf is the term for the width of the carbide teeth. A full kerf is 1/8″, whereas thin kerf is just 3/32″.
How thick is a saw blade cut?
The 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.
How wide is a circular saw blade cut?
The most common blade diameter is 7-1/4 inches. Most saws with blade capacities of 6 inches or more can cut through 2-inch dimensional lumber at a 45-degree angle in a single pass.
What is the purpose of a kerf?
A full kerf blade’s thickness makes it sturdy and durable. It also allows for precise cuts, even on thick pieces of wood. These blades are best used with saws with three horsepower or more since they can handle its larger size easier.
