TOOTH STYLE
When selecting blades, another
option to consider is the shape,
gullet size, teeth set and teeth
angle, otherwise known as Tooth
Style. Many blade manufacturers
offer variations of the four basic
styles, as shown.
•
Standard
: This style is considered to be the standard because the tooth size
and shape are the same as the tooth gullet. The teeth on these blades
usually are very numerous, have no angle and produce cuts by scraping
the material; these characteristics result in very smooth cuts, but do not cut
fast and generate more heat that other types while cutting.
•
Skip
: This style is similar to a raker blade that is missing every other tooth.
Because of the design, skip toothed blades have a much larger gullet than
raker blades, and therefore cuts faster and generate less heat. However,
these blades also leave a rougher cut than the raker blades.
•
Hook
: The teeth on this style have a positive angle (downward) which
makes them dig into the material and the gullets are usually rounded for
easier waste removal. These blades are excellent for the tough demands
of re-sawing and ripping thick material.
•
Variable Pitch
: These blades typically feature combinations of tooth styles
that provide qualities of both.
TOOTH SET
Three of the most common tooth
sets are Alternate, Wavy & Raker
