How to Use a Drill Press Machine

For example, a peripheral speed of 30 feet per minute means the drill would roll 30 feet in 1 minute if rolled on its side. It has been determined through experience and experiment that various metals machine best at certain speeds; this best speed for any given metal is what is known as its cutting speed (CS) (see Table 4-2) in Appendix A.
