To begin with, the number of th that a blade has will significantly affect its per
mance. For simply powering through large amounts of lumber quickly and efficiently, a blade with fewer
th will be an ideal choice. A blade with around 20
th will tear through lumber easily. The drawback
e, however, is that the
it makes will be at least somewhat rough along the edges. On the ot
hand, such a saw will operate very quickly and get the job done in a minimum amount of time.
At the opposite end of the spectrum, can find saw blades with as many as 80
th. When a blade has this many
th, it will make very smooth
s along the edge, leaving
r workpiece with a polished appearance. This type of blade is best used in situations when the edges must be very smooth, such as in furniture production. These blades are commonly known as cross
saws. The drawback with a cross
saw is that it will not operate as quickly as a rip
saw with fewer
th.
Anot important factor when choosing the right saw blade is the gullet of the blade. The gullet of a blade is the crevice inbetween each tooth. The gullet takes the excess material from the workpiece and ejects it, allowing the blade to continue along. A shallow gullet will slow the saw blade and encourage a smoot
along the edge. A deep gullet along the saw blade will give the blade a bigger bite, allowing it to run along the wood faster.
Saw blades also have varying types of th configurations. A flat top tooth is best
ripping through wood, and will work quickly and efficiently through a piece of wood. For a smoot
, however,
might want to choose an alternate top bevel (ATB) type tooth, which uses a more knife-like action to create a smoot
edge. For the absolute smoothest
, go
som
ing like a high alternate top bevel (HiATB).
The hook angle of the blade th is anot
factor to look at carefully. A high
ward hook angle, or positive angle, will assist the blade in
ting rapidly through the material. A negative hook angle, or
th that are angled opposite the direction of the blade, will slow down the saw and prevent too much material from being feed into the blade.
These are some of the most important factors when it comes to choosing a saw blade. With this knowledge, should be able to pick out an appropriate saw blade
r particular needs.
