Portable Tool Boxes and Chests

Steel gives the best impact and crush resistance and is the standard choice for job-site abuse, but it's the heaviest and can rust without a good finish. Plastic is lightweight, corrosion-proof, and lower cost, suited to lighter tool loads and environments with moisture exposure. Aluminum sits between the two — lighter than steel with good corrosion resistance, at a higher price point, often chosen for truck-mounted or frequently carried boxes.

Check both the per-drawer rating and the total chest rating — a chest can have a high total capacity but individual drawer slides rated much lower, which matters if you're loading dense items like sockets or hand tools into a single drawer. Also confirm the wheel and caster rating, since a fully loaded chest that exceeds the wheel rating will roll poorly and wear out faster.

If the box will be stored outdoors, on a truck bed, or exposed to rain and dust regularly, a gasketed lid is worth the added cost — it keeps moisture and debris away from tools that would otherwise rust or bind. For indoor shop or van storage where the box is rarely exposed to the elements, a non-sealed box is usually sufficient.

A cantilever box has trays that pivot open like a fan when the lid is raised, giving visibility and access to every tray at once without lifting them out — convenient for frequently used small tools. A standard tray-style box has a single lift-out tray over a lower storage compartment, offering more bulk storage space but less at-a-glance organization.

If tools need to move only occasionally and by hand, a fixed-handle box is lighter, cheaper, and simpler. If the total tool load is heavy — a full mechanic's set, for example — or needs to move frequently around a shop or job site, a rolling chest with wheels and drawer slides saves the physical strain of carrying it and typically offers more organized drawer storage.
