12.0 Non-Metal Blade Chart
Identify the material and thickness of your workpiece. Table 3 will show the recommended PITCH, blade TYPE,
and FEED RATE.
Key: H – Hook L – Low
S – Skip M – Medium
R – Regular H – High
Example: 10/H/M means 10 teeth per inch / Hook Type Blade / Medium Feed

Study the part drawing or prototype, or actually measure the smallest cutting radius required, and locate this
radius (in inches) on the chart at the right. Follow the curve to where the approximate blade width is specified. If
a radius falls between two of the curves, select the widest blade that will saw this radius.
This procedure should be used for making initial blade selections. These recommendations can, of course, be
adjusted to meet specific requirements of a cutting job. Compromises may be necessary if you cannot find all
needed specifications in a single blade.
