Selecting the right blade requires a knowledge of the
various blade characteristics to match the blade with the
particular cutting operation.
Blade Length
Measured by the circumference, blade lengths are usually
unique to the brand of your bandsaw and the distance
between wheels. The Model W1749 is designed for blades
that are 59
1
⁄
4
" long.
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.
The Model W1749 can use blades from
1
⁄
8
" to
3
⁄
8
" in
width. Always pick the size of blade that best suits your
application.

Curve Cutting:
Use the chart in
Figure 48
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. Narrow blades can cut tight curves
(a small radius) but are not very good at cutting
straight lines because they naturally wander (blade
lead). However, larger blades are much better at
cutting straight lines, but function poorly at cutting
small curves because of their size.
