Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of the saw blade; the set of the blade’s teeth; the amount of wobble created during cutting; and the amount of material pulled out of the sides of the cut.Click to see full answer. In this regard, what is saw kerf width?Kerf Thickness. Saw blade “kerf” refers to the thickness of the slot which the saw blade will cut. It is often used as well to define the thickness of the blade itself, or at least the widest point on the blade, as this will define the width of cut made. Kerf is generally wider than the blade plate.Secondly, what is meant by kerf and setting of saw? The term “kerf” is used to describe the thickness of the cut a woodworking saw blade makes in a piece of wood as it cuts through it. 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. Accordingly, what is the purpose of a kerf board? The purpose of the kerf board is to reduce tearout on the workpiece. It is necessary to hold the workpiece by hand while cutting a miter because clamps would get in the way of the cut. The capacity to make consistent repetitive cuts is considered one of the true strengths of the sliding compound miter saw.What is a full kerf blade?Full 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″. 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.
