🔩 Drill bits

Drill bits are sharp tools and prohibited in carry-on in most regions, so a screener will stop you and confiscate them or ask you to return to check-in. If you have time before your flight, checking the bag is the better option. Otherwise the bits will be surrendered at the checkpoint.

The US TSA prohibits sharp tools, including drill bits, from carry-on baggage. The EU and UK follow essentially the same rule for sharp pointed tools. No major aviation region permits drill bits in the cabin, making checked baggage the only viable option for transporting them by air.

Drill bits are dense metal objects that show up very clearly on an X-ray, so screeners will almost always spot them. If stopped, simply acknowledge the error and ask whether you have time to return to check-in — screeners are generally reasonable about genuine mistakes with items like tools. Do not attempt to argue that small bits are not sharp.

Always pack drill bits in checked baggage, ideally in their original indexed case so the bits are secure and cannot pierce through the bag lining. Loose bits rolling around inside a suitcase can puncture clothing and create a messy X-ray image. If you are travelling with only carry-on, ship the drill bit set separately or buy bits at your destination.
