Circular Saw Blade Anatomy and Grind Types

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.

Circular Saw Blade Anatomy – Tooth Grinds

Flat Top Grind (FTG) – best for ripping


Alternate Top Bevel (ATB) – for cross-cutting, cut-off and trimming


Triple Chip Grind (TCG) – perfect for hard, abrasive materials like non-ferrous metals, hardwoods and plastics


Multi-Purpose Carbide Tipped (MCT) – for ripping and crosscutting, miter


Tri-Grind (TRI) – combination grind


Left Trim Grind (3/1) – good finish, one side only


Right Trim Grind (3/1) – good finish, one side only


Solid Surface Grind (SSG) – for extremely dense man-made materials


High 30 degree ATB (MH) – chip-free cuts on melamine and plywood
