Drilling, Enlarging, and Deburring Holes

Prior to installing fasteners in any assembly, pilot holes must be drilled. Because pilot holes are
not large enough to accommodate fasteners, the pilot holes must be enlarged to size. Any burrs
that form during the drilling process must also be removed.
By the end of this course, you will be able to
• 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 with a Go/NoGo pin gauge
• Use an open countersink to deburr holes
