Learn the importance of circular saw blade anatomy

Tooth design is the determining factor in deciding which blade is best for any application. Here’s a quick overview of how subtle changes in bevel, gullet and kerf affect cutting performance.

Bevel – Teeth can have a single bevel, two bevels or no bevel at all. Types of bevels can alternate from tooth to tooth on a given blade. The bevel is what gives a blade its specific cutting pattern.

Gullet – This is the space between teeth that clears the work piece of chips after the cut. The deeper the gullet, the more efficiently chips are cleared.

Kerf – This is the face of the tooth, where the actual cutting takes place. The pattern of alternating kerfs, known as the grind, decides what applications a blade is best for.
