That was an excellent description of a tap collection for
fabrication.

The sets are good for repair work, like cleaning up corroded male and
female threads on outdoor equipment or tapping stripped holes larger.
You can use them to find the size of a lost screw to buy a
replacement.

I use a Huot index for the drill and one good tap in each size and
keep the rest in drawers with nylon or brass nuts screwed on to
protect them from each other.
