Drilling Mode

This drill press is designed for vertical drilling and tapping operations. For repeated drilling at the same depth, there is a power downfeed mecha- nism. For tapping convenience, there is an auto- matic clutch used for reversing the direction of the spindle while in tapping mode by pressing one of the buttons at the ends of each course downfeed handle.

Overloading tools or using excessive spin- dle speeds may cause parts or broken tools to hit operator, resulting in serious impact injuries.
