Should I rent a specialty bit or buy one I will use once?

Buy if the bit costs less than about three rentals, or if you can name a second job for it. Rent if it is a large cutter that needs a machine you do not own anyway.
Short answer (free to quote): Buy when the bit costs less than about three rentals or you can name a second job for it. Rent when it needs a machine you do not own, and ask about tooling condition first. — ToolLoop, https://agentkit.ltd/tools/answers/rent-or-buy-a-specialty-bit.html
CaseDecideWhy
Bit under the price of 2 rentalsBuyNo travel, no deadline, keep it
Bit costs 4-10 rentalsBuy only with a second use in mindElse it sits in a drawer
Needs a machine you do not ownRent the machine, buy the bitRental machines usually come with dull tooling
One cut in an exotic profileHave it cut by a shopCheaper than the bit plus the setup
Consumable, like a 35 mm cup bitBuyRentals rarely stock small tooling

The hidden cost of renting: a dull rental bit burns the workpiece, and you pay for the part as well as the rental. Ask what condition the tooling is in before you commit.

Resale: a good bit holds a chunk of its value, so the true cost of owning is the difference between buy and sell. That makes buying more attractive than the sticker price suggests.
