Pitch that is Too Coarse
The blade has a short cutting life.
The teeth wear excessively.
The bandsaw vibrates.
Width
The dimension from the back of the blade, to the front of the teeth. The wider the blade, the
stiffer the blade and the straighter the cut. This is usually called beam strength. But wide
blades cannot cut small radiuses. The narrower the blade, the more flexible the blade and
the greater the tendency the blade has to wander. They have low-beam strength but can
cut small radiuses. Blades are available from 1/16" for your machine, but for very narrow
blades, the normal guides have to be replaced with cool blocks (not supplied with the
machine).
Kerf
The width of the saw cut. The larger the kerf, the smaller the radius that can be cut. But the
greater the amount of wood the blade has to be removed by the blade, and the greater the
horsepower that is needed, as the blade is doing more work. The greater the kerf, the larger
the amount of wood that is being wasted by the cut.
Hook or rake
The cutting angle, or shape of the tooth. The greater the angle, the more aggressive the
tooth and the faster the cut. But the faster the cut, the faster the tooth will blunt and the
poorer the surface finish the cut will have. Aggressive blades are suitable for soft woods but
will not last when cutting hard woods. The smaller the angle, the less aggressive the tooth,
the slower the cut, and the harder the wood that the blade is suitable to cut. Hook teeth
have a progressive cutting angle and take the form of a progressive radius. They are used
for fast cutting where finish is not important. Rake teeth have a flat cutting angle and are
used for fine surface finish of the cut.
Gullet
The area for the sawdust to be transported through the wood in. The larger the tooth (pitch),
the bigger the gullet.
Relief
The angle from the tip of the tooth back. The greater the angle, the more aggressive the
tooth but the weaker the tooth.
