Pilot holes are typically the first holes drilled in any assembly. They are usually too small to
accommodate the shank of any standard fastener, so they must be enlarged before fasteners
can be installed in the assembly.
By the end of this course, you will be able to
• Create a drill start with a drill motor and pilot bit
• Drill a pilot hole
• Exchange a pilot bit for a larger drill bit
• Set a drill stop
• Enlarge a hole to size
• Inspect a full size hole using a Go/NoGo pin gauge
