Efficient tang break-off is dependant upon several conditions, the
correct diameter tool being the most obvious factor. However sufficient
thread must exist in the tapped hole to provide the necessary support
at the tang elbow and adequate clearance beyond the insert must be
present to allow for tang deflection.
Assuming those conditions apply, de-tanging is a very simple operation
to perform. The specified limits for drilling and tapping lengths
in tabulated form, have been calculated to ensure such conditions.
