BLADE SELECTION GUIDE
TEETH PITCH AND RAKE
Regular tooth
0° rake and constant pitch.
Regular tooth blades are typically used for crosscut or
inclined cutting in small solid and average cross-section cuts
in or pipes, laminated mild steel, gray iron or general metal.
Positive rake tooth
9°-10° positive rake and constant pitch.
This blade is used for crosscut or inclined cuts in solid
sections or large pipes, including all harder materials (highly
alloyed and stainless steels, special bronze and forge pig
iron).
Combo tooth
This blade has pitch variations between teeth and variations
in teeth size along with variable gullet depths. These unique
parameters ensures a smoother, quieter cut, and longer
blade life due to the lack of vibration.
Another advantage offered by the use of this blade is its
ability to cut wide range of different material sizes and
shapes.
Combo tooth
9°-10° positive rake.
This blade type is suitable for the cutting of section bars and
large and thick pipes as well as for the cutting of solid bars at
machine capacity. Available pitches: 3-4, 6-8.

TEETH SET
Saw teeth are slightly bent out of the plane of the saw body,
resulting in a wide cut in the workpiece. This parameter is called
"tooth set."
Regular or raker set
The cutting teeth are set right and left, alternated by a
straight tooth.
For use for materials with dimensions greater than .2".
Used for the cutting of steel, castings and hard nonferrous
materials.
Wavy set (in smooth waves).
This tooth set is associated with very fine teeth and is mainly
used for the cutting of pipes and thin section bars (from .04"
to .118").
Alternate set (grouped teeth)
Teeth are set in alternate groups of both right and left
separated by a straight tooth.
This tooth set is used for smooth cuts in extremely thin
materials (less than .04").
Alternate set (individual teeth)
The cutting teeth are individually set right and left.
This type of tooth set is used for the cutting of nonferrous soft
materials, plastics and wood.
