Can You Take a Home Tool Kit on a Plane?

The short rules for carry-on and checked bags

TSA's published guidance for tools draws a simple line. Tools 7 inches or shorter may be allowed in carry-on baggage. Power tools and tools longer than 7 inches need to be packed in checked baggage. The length is measured on the tool itself, not the case.

That means a full home tool kit in a hard case will usually fail a carry-on check, even if some of the tools inside are small enough. The case is one problem. A hammer, a long wrench or a utility knife is another. When in doubt, check the whole kit.

Rules can change, and airlines may add their own limits. Look at the TSA "What Can I Bring?" page and your airline's baggage page before you leave home.

What usually goes where

Most home kits mix small items with long ones. Sorting them before you pack saves you from a surprise at security. The table below shows the usual approach based on TSA's length rule and general screening practice.

How to pack a tool kit in checked luggage

A little care keeps your tools, your clothes and the baggage handlers safe. Metal tools are heavy and sharp, so they should not shift around in a soft suitcase.

• Keep the kit in its own hard case, and latch it fully.
• Cover or sheathe any blades, including utility knife blades.
• Wrap loose items such as hex keys and bits so they cannot spill if the case opens.
• Place the case in the middle of the suitcase, cushioned by clothes.
• Put a note with your name and contact information inside the case.
• Expect that TSA may open and inspect the bag. Leave the case easy to close again.

Weight matters more than you think

Tools are dense, so a kit can use up much of your checked weight allowance. Many airlines set a per-bag weight limit and charge for bags over it, so check your airline's limit before you pack.

The kits on our best home tool kit page show how wide the range is. Listed weights run from 5.07 lb to 39.19 lb. The 192-piece DEWALT mechanics set lists 39.19 lb, which is a large share of a typical bag limit on its own. The CRAFTSMAN 57-piece mechanics set lists 7.25 lb, and the DEKOPRO 228-piece kit lists 12.78 lb in a case 17.5 in long.

If you fly often with your tools, a lighter and more compact kit is easier to manage. Case length also matters for fitting a suitcase. Among products that list it, case length runs from 6.97 in to 17.9 in.

Which kind of kit travels best

Kits built around sockets are heavy and often have many small parts that are easy to lose. A basic starter kit is simpler to pack. The DEKOPRO 94-piece basic home tool kit comes in a hard case and lists a 4 oz steel claw hammer, 5.5-inch combination pliers, a utility knife, a 6.56-foot tape measure, hex keys and bits. Its pliers are under the 7-inch line, but the utility knife means the case still belongs in checked luggage.

If you only need a few tools at your destination, think about packing just those. A short screwdriver, a small pair of pliers and a tape measure can be enough for furniture assembly, and they may be allowed in a carry-on. Leave the knife and hammer at home or put them in your checked bag.

When you compare kits for travel, look at total weight, case length and what the listing actually includes. Our guide to choosing a kit explains how to read those specs.

Power tools and batteries

Power tools never go in a carry-on under TSA's rule. A cordless drill or driver must be checked. Batteries are a separate issue. Lithium batteries come with their own limits, and spare lithium batteries are generally required to travel in carry-on bags rather than checked bags, with size limits that vary. Check the FAA and your airline's rules for the exact watt-hour limits before you fly.

If you are shopping for a drill kit that you may travel with, our best power tool combo kit for the money page lists what each set includes. Look at what batteries come in the box, since that affects how you pack.

As a safety note, never pack loose batteries where metal tools can touch the terminals. Tape over exposed terminals or keep each battery in its own case or bag.

A simple pre-flight checklist

Run through these steps a few days before your trip.

• Open the TSA "What Can I Bring?" page and look up each tool.
• Read your airline's baggage page for weight and size limits.
• Weigh your packed case on a bathroom scale.
• Remove blades, or cover them securely.
• Move spare batteries to your carry-on, following airline rules.
• Keep your packing list handy in case of questions.

Frequently asked questions

Can I bring a screwdriver in my carry-on?

Usually yes, if it is 7 inches or shorter. Longer screwdrivers need to go in checked baggage. A TSA officer makes the final decision at the checkpoint.

Will TSA open my tool case?

They may. Checked bags can be inspected, so latch the case well and expect to find it repacked. A hard case with a clean layout is easier to close again.

Can I ship a tool kit instead of flying with it?

Yes. Shipping can make sense for a heavy kit, since it avoids checked bag weight limits. Compare the carrier's cost and timing against your airline's fees before you decide.

Are small travel tool kits treated differently?

Not as a category. Each item is judged on its own, mostly by length and type. A small kit with a knife or long tool still goes in checked baggage.
