Blade Characteristics

(Wood Cutting)

Blade Length

Measured by the circumference, blade lengths are usually

unique to the brand of your bandsaw and the distance

between wheels. This saw uses 133" long blades.

Blade Width

Measured from the back of the blade to the tip of the

blade tooth (the widest point), blade width is often the

first consideration given to blade selection. Blade width

dictates the largest and smallest curve that can be cut, as

well as how accurately it can cut a straight line.

This saw uses blades from

" to 1

" in width. Always

pick the size of blade that best suits your application.

Curve Cutting: Use the chart in Figure 43 to deter-

mine the correct blade for curve cutting. Determine

the smallest radius curve that will be cut on your

workpiece and use the corresponding blade width.

Straight Cutting: Use the largest width blade that

you own. Large blades excel at cutting straight lines

and are less prone to wander.

Tooth Style

Figure 45 illustrates the three main tooth styles:

Raker: Considered to be the standard because the

tooth size and shape are the same as the tooth

gullet. The teeth on raker 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 than other types while cutting.

Skip: 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, cut faster and generate less heat.

However, these blades also leave a rougher cut than

raker blades.

Hook: The teeth 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

resawing and ripping thick material.
