Major Work Activity D – Machines using drill presses
Task D-10 Sets up drill presses
Task Descriptor
Machinists use drill presses to drill, ream, bore and tap holes. Drill presses are also used to perform cutting operations such as countersinking, counterboring, chamfering and spot facing. Drill presses are an integral part of a machine shop. Comprehensive drill press skills are essential for fully qualified machinists.
Setting up drill presses is an important task which must be done to maximize quality and efficiency.
