Blade Terminology

Selecting the right blade for the cut requires a

knowledge of various blade characteristics.

Blade Terminology

A. Kerf: The amount of material removed by the

blade during cutting.

B. Tooth Set: The amount each tooth is bent

left or right from the blade.

C. Gauge: The thickness of the blade.

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 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. TPI: The number of teeth per inch measured

from gullet to gullet.

will be cutting metal, refer to Page 37 for addi

tional considerations

Blade Length

Measured by the circumference of the band,

blade length varies by saw.

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 selec

tion. 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.

• Curve Cutting: Determine the smallest radi-

us curve that will be cut on your workpiece

and use the list below to select the correct

blade width.

• Straight Cutting: Use the largest width

blade that you own. Narrow blades can cut

tight curves (a small radius) but are not very

good at cutting straight lines because they

naturally wander (blade lead). Wide blades

excel at cutting straight lines and are less

prone to wander.
