D.Blade Width: The widest point of the blade measured from the tip of the tooth to the back edge of the blade.

E.Tooth Rake: The angle of the tooth face from a line perpendicular to the length of the blade.

F.Gullet Depth: The distance from the tooth tip to the bottom of the curved area (gullet).

G.Tooth Pitch: The distance between tooth tips.

H.Blade Back: The distance between the bot- tom of the gullet and the back edge of the blade.

I.Blade Pitch or TPI: The number of teeth per inch measured from gullet to gullet.

Blade Length

Measured by the blade circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between the wheels.

Model	Blade Length

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the first consideration given to blade selection. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line—generally the wider the blade, the straighter it will cut.
