What You Should Know About Circular Saw Blades
Tooth design is the determining factor in deciding which blade is best for which industrial application.
Here's a quick overview of how subtle changes in bevel, gullet and kerf affect cutting performance.
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 the blade its specific cutting pattern.
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.
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.
There are many types of grinds, but the five basic ones are:
Flat top grind (FTG)
Best for ripping.
Alternate top bevel (ATB)
For crosscutting, 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, mitre.
