Tooth Style Selection
Economies of cutting can be achived by chosing the tooth
style or shape correctyle suiled to the being cut.Saving can
be made by selectong the best tooth style because of:Faster
sawing,more accurale sawing,longer blade life abd less
breakage of teeth,
The following four (4) tooth styles are avaible.
Standart Tooth (N)
0° rake angle,fully rounded gulet,general purpose
Skip Tooth (L)
0° rake angle,low tooth height,flat gulet-to be used for bitle
materials of larger diameters,i.e.
bronce,brass,zinc,aluminium gales & risers,plastics.
Hook Tooth (KL)
10° positive rake angle with wide spacing between
tips,deep gulles-suitable for NF-metals,low carbon
steeli,large diameters.
Combi Tooth and Positive
The tooth pitch varies thougth the blade,regular,tooth
patlern broken up the reduce noise,less vibration and
chatler,longer balde lifesuitable for a wide range of cutting,
İ.e. structurals,pipe,tubing and micellaneous steels.
Tooth Set Selection
The purpase of ‘sel’ in a bandsaw blade is to provide
clearance and to allow the body of the blade to pass freely
though the materiall being cut.The sel depends on stock
diameter,shape and material to be cut.
Regular or Raker-Set
Is the most widly used setting.If consits of a repetitiv
patlern with one tooth set the right,the next to the left and
the third(the raker)wilhout set.This type of set is best
where the material being cut is uniform size;also used in
contour sawing.
Right-Left Set
For sofler materials, i.e. NF-metals,plastic&wood.
Group Set
For vibration free sawing of smaller diameters such as pipe
tubing and shapes-faster cutting speeds and smoother
sufaces.
Wavy Set
Spaceial set for cutting thin stock or variely of shapes and
thicknesses without changing the blade.
Combi Tooth Set
With 0° rake angle.Consisles pf teeth set allernately right
and left regular intervals with a raker tooth-excellen for
cuttin a variely of shapes and pipes 15mm wall thivkness
and upwards.
