Understanding sawmill blade geometry and terminology can be complex. Here is a crash course in identifying different parts of a bandsaw blade and how to choose a blade profile that is best suited for your sawing application.
A. Tooth Spacing - the distance between each tooth from one tip to another. The term "pitch" is also used in reference to tooth spacing as the number of teeth per inch on a bandsaw blade.
B. Gullet - the area between teeth that captures and removes sawdust while providing strength in the tooth. The tooth height must be tall enough to allow the gullet to carry out all of the sawdust from the cut.
C. Tooth Height - the distance from the lowest point of the gullet to the tip of the tooth.
D. Hook Angle - the number of degrees that the tooth face leans forward of 90 degrees. The hook angle should be chosen based on the type of wood you are sawing.
E. Tooth Set - distance the tooth is bent beyond the body of the blade.
F. Blade Width - distance between the tip and base of the blade.
G. Blade Thickness - you guessed it! Thickness of the blade.
H. Kerf - the width of the cut.
