The Importance of the Kerf in Circular Saw Blades
When it comes to circular saw blades, the kerf is an important consideration. The kerf refers to the width of the cut made by the blade as it slices through material. It is essential to understand the significance of the kerf to ensure optimal performance and desired results.
What is Kerf?
Kerf is the measurement of material that a saw blade removes as it cuts. It is determined by the thickness of the blade and the set, which is the distance the teeth are bent outward from the blade’s centerline. The kerf width impacts the efficiency and speed of the cutting process.
Effects of Kerf Width
The thickness of the kerf affects several aspects of using a circular saw blade:
| Effect | Description |
|---|---|
