Blade Speeds and Chip Loads

When picking a blade for a project, one must keep in mind that certain blades are suited to certain materials

To help with this, we have some charts below, to help you make the best decision.

Chip Load Per Tooth

 

Recommend Chipload

Minimum
Maximum
 
Along Grain
0.008"
0.035"
Cross Grain
0.004"
0.008"
Hardwood
0.002"
0.006"
Chipboard
0.001"
0.004"

Veneered Panels

0.008"
0.035"

For Example: A 60 Tooth saw rotating at 3000 rpm with a feed rate of 80fpm will have a chipload of 0.005"

To help calcuate chipload values, use the following formula:

Chipload = (12 * feed per minute) / RPM * number of teeth.
