Blade Characteristics

TYPES OF TOOTH SET The types of tooth sets is the sequence used in offsetting the teeth. Raker Set— Sawing ferrous and tough metals

BLADE GEOMETRY Terminology

Straight Set— Easily machined metals and non-metals

Straight Raker Set— Used for all multipitch blades

A. Width of the blade B. Thickness (gauge)

E. Rake angle

F. Clearance angle G. Width of set (kerf)

C. Gullet depth D. Tooth pitch

RADIUS CHART Contour cuts use the widest blade that cuts the smallest radius needed for the job. The blade width is measured from the tooth tips to the back edge.

TOOTH PITCH Pitch (teeth per inch or TPI) is a measure of tooth spacing. Single Pitch

Blade Width 1" (27 mm)

Radius 7 1/4" (185 mm)

1" (25.4 mm)

Blade Width 3/4" (20 mm) Blade Width 5/8" (16 mm) Blade Width 1/2" (13 mm) Blade Width 3/8" (10 mm) Blade Width 1/4" (6 mm) Blade Width 3/16" (5 mm) Blade Width 1/8" (3 mm)

Radius 5 1/2" (140 mm) Radius 3 3/4" (95 mm) Radius 2 1/2" (65 mm) Radius 1 1/2" (37 mm) Radius 1/2" (15 mm) Radius 5/16" (8 mm)

For fast cutting materials. Single pitch blades have consistent tooth spacing. The number of teeth per one- inch length is the TPI. Multi Pitch

For most metal sawing applications. Multi pitch blades vary tooth spacing between two extremes. The pitch designation of a multi pitch blade hyphenates the equivalent single pitch designations of those extremes. TOOTH SHAPES Tooth forms are combinations of rake angle and gullet shape. Rake angle is a measure of the tooth face inclination to the work. Rake angles are neutral or positive.

Radius 1/8" (3 mm)

Cutting Edge

Positive Rake

Precision Used for most sawing applications Claw/Hook Increases beam strength and penetration

Precision 0° to 18° rake

Claw 10° rake

Negative Rake
