Can You Bring Power Tools on a Plane?

Power tools are banned from carry-on bags but allowed in checked luggage. That's the short answer. The longer answer involves battery rules, airline policies, and some packing strategies that'll save you a headache at the airport.

TSA Rules for Power Tools

The TSA is clear on this one: power tools are not permitted in carry-on bags. They must go in your checked luggage. This applies to all power tools, including:

• Cordless drills and impact drivers
• Circular saws and reciprocating saws
• Sanders and grinders
• Nail guns
• Jig saws
• Rotary tools (like Dremels)
• Heat guns
• Power planers

The rule covers both corded and cordless tools. Even if a cordless drill is small enough to fit in your carry-on, it still needs to go in your checked bag. The TSA categorizes power tools alongside items like saws and axes: fine for the cargo hold, not fine for the cabin.

The Battery Problem

Here's where most people get tripped up. If your power tool runs on a lithium-ion battery (and most cordless tools do), there are specific rules you need to follow. These rules exist because lithium-ion batteries can catch fire if they short-circuit, and a fire in a checked bag in the cargo hold is far more dangerous than one in the cabin where crew can respond immediately.

Batteries Installed in the Tool

You can check a power tool with the battery still installed, but it must be completely powered off and protected from accidental activation. The best way to do this is to pack it in the manufacturer's hard case with the trigger lock engaged. If you don't have the original case, wrap the trigger area so it can't be accidentally pressed, and consider putting the whole tool in a sturdy box.

Some travelers put a strip of tape over the trigger as an extra precaution. It's a small step that makes a real difference, especially with impact drivers that have hair triggers.

Spare Batteries

This is the critical rule most people miss: spare lithium-ion batteries cannot go in checked bags. They must be packed in your carry-on. This isn't a TSA rule. It's an FAA regulation, and airlines enforce it strictly.

If you're bringing extra DeWalt or Milwaukee batteries for a job, those batteries ride in the cabin with you. Each battery needs to be individually protected from short circuits. That means keeping them in their original packaging, taping over the terminals, or putting each one in a separate plastic bag or protective pouch.

Why the cabin and not the cargo hold? If a lithium battery starts to overheat in the cabin, the flight crew can deal with it. In the cargo hold, a thermal runaway event could go undetected until it's too late. This rule isn't arbitrary. It's based on real incidents.

Watt-Hour Limits

Lithium-ion batteries are limited to 100 watt-hours (Wh) per battery without special approval. Most standard 18V/20V power tool batteries (like the common 2.0Ah or 4.0Ah packs) fall under this limit, so you're fine.

Here's a quick reference for common battery sizes:

• 18V / 2.0Ah = 36 Wh - Well under the limit
• 20V / 4.0Ah = 80 Wh - Under the limit
• 20V / 5.0Ah = 100 Wh - Right at the limit, still allowed
• 40V / 4.0Ah = 160 Wh - Needs airline approval, max 2 spares
• 60V / 6.0Ah = 360 Wh - Banned from passenger aircraft

Batteries between 101 and 160 Wh require airline approval, and you're limited to two spare batteries in that range. Check the label on your battery. The watt-hour rating is usually printed on it, or you can calculate it by multiplying voltage by amp-hours (V x Ah = Wh).

Batteries over 160 Wh are banned from passenger aircraft entirely. If your tool uses a battery this large, you'll need to ship it separately or buy or rent one at your destination.

Hand Tools vs. Power Tools

The rules are different for hand tools, and the distinction matters. Hand tools that are 7 inches or shorter in length are allowed in carry-on bags. This includes:

• Screwdrivers (7 inches or shorter)
• Wrenches (7 inches or shorter)
• Pliers (7 inches or shorter)
• Socket sets
• Allen keys
• Tape measures

Hand tools longer than 7 inches must go in checked bags. And anything with a blade, like a utility knife or box cutter, is always banned from carry-on regardless of size.

The 7-inch measurement is overall length, not just the blade or working end. A 9-inch adjustable wrench goes in checked luggage even though it isn't sharp or particularly dangerous.

Packing Power Tools for Checked Luggage

Throwing a drill into your suitcase isn't ideal. Here's how to do it right:

• Use the original hard case. It's designed to protect the tool and keeps everything secure. Most manufacturer cases also lock, which is a bonus for checked luggage.
• Remove the battery and pack it in your carry-on. This is the safest approach and eliminates any confusion at the check-in counter.
• Wrap blades and bits. Any sharp components like saw blades, drill bits, or router bits should be sheathed or wrapped. The TSA requires this to protect baggage handlers.
• Secure loose parts. Tighten chucks, lock blade guards, and make sure nothing can rattle around or activate the tool during handling.
• Pad everything. Checked bags get thrown, dropped, and stacked. Wrap tools in clothes or bubble wrap to prevent damage to both the tool and your luggage.
• Consider shipping instead. If you're bringing a lot of tools, it might be cheaper and easier to ship them via UPS or FedEx. Airlines charge for overweight and oversized bags, and a bag full of tools will be heavy.

Airline-Specific Policies

While the TSA sets the security rules, individual airlines can add their own restrictions. Some things to check with your carrier:

• Weight limits. Checked bags typically have a 50-pound limit before overweight fees kick in. Power tools are heavy. A drill, two batteries, and a set of bits in a hard case can easily weigh 15-20 pounds on their own. Weigh your bag before heading to the airport.
• Oversized bag fees. If your tool case is larger than standard luggage dimensions (typically 62 linear inches), you may get hit with oversized baggage fees that can run $100-$200 each way.
• Battery policies. Some airlines have stricter battery policies than the FAA minimum. It's worth a quick check on your airline's website or a call to their customer service line.
• Number of checked bags. If you're checking a suitcase plus a tool case, that's two checked bags. Know what your ticket includes before you show up at the counter.

What About Corded Power Tools?

Corded power tools don't have the battery complications, which simplifies things considerably. They still must go in checked luggage (never carry-on), but you don't have to worry about watt-hour limits or carrying batteries separately. Just make sure any blades are covered and the tool is secured so it can't accidentally switch on. Wrap the cord neatly and secure it with a velcro strap or zip tie so it doesn't tangle with other items.

Nail Guns Deserve Special Mention

Nail guns are allowed in checked bags, but they require extra care. They must be completely unloaded (no nail strips or cartridges loaded) and packed so they can't accidentally fire. If your nail gun uses compressed gas cartridges, check the FAA's hazmat rules because some gas-powered fastener cartridges have restrictions. Pneumatic nail guns that don't carry their own power source are simpler since you just need to make sure they're empty.

Shipping vs. Flying With Tools

For contractors and tradespeople traveling for work, shipping tools often makes more sense than checking them as luggage. Here's the math:

• Checked bag fees: $35-$75 per bag for most domestic airlines, plus potential overweight surcharges of $100+ for bags over 50 pounds
• Shipping via UPS/FedEx: $30-$80 for a medium-sized tool case via ground shipping, or $50-$150 for overnight

Shipping eliminates the hassle of dealing with batteries at security, the risk of tools getting damaged by baggage handlers, and the weight restrictions. You can ship batteries with the tools (ground shipping allows lithium batteries that airlines restrict). Many hotels and job sites will accept packages, so you can ship ahead and have your tools waiting for you.

International Flights

If you're flying internationally, the destination country may have its own import rules for tools. Some countries restrict or tax tools being brought in, especially if they look like they're for commercial use rather than personal use. Check customs regulations for your destination before packing a full tool bag. In some cases, you may need to declare the tools at customs and prove they'll be leaving the country with you.
