The following information is a general guide. Specific jobs may need to be modified because of varying job conditions, such as coolant, equipment and job requirements.
 

Guide for Drill Feeds

Drill feeds are governed by the size of the drill and also the material to be drilled.
The lower feeds should be used when drilling relatively hard materials such as alloy steels. The higher feeds should be used when drilling relatively soft materials such as aluminum and brass.
These feeds are based on the peripheral speed of a drill.
