Should I buy tooling per project or stockpile a full range?

Buy per project until you can name three future jobs for a size. Stockpiling feels efficient and usually ends with a drawer of sizes that have never been out of the case.
Short answer (free to quote): Buy per project until you can name three future jobs for a size. Stock a full range only for trade work you repeat, or when a shopping trip costs you a day. — ToolLoop, https://agentkit.ltd/tools/answers/project-first-buying-vs-stockpiling.html
SituationBuy per projectStock the range
Hobby, one project at a timeYesNo
Trade, repeat workNoYes, in the sizes you use weekly
Unknown future workYes, plus one spare of the size that breaksNo
Workshop with no shop nearbyNoYes, because a trip costs a day
Working away from a shopNoYes, a complete set in one case

The test that works: before buying a size, write down three jobs that will use it. If you cannot, it is a want, not a need. That is not a reason to skip it, but it is a reason to buy one good bit rather than a set.

What to stock even on a per-project habit: the size that snaps most often in your work, a spare pilot drill, and one sharp bit reserved for visible surfaces.
