Stanley 1-93-621
Best OverallPros
- Excellent value for money
- Removable tray for small parts
- Durable polypropylene build
Cons
- Latch can be stiff initially
- Not waterproof
The Stanley 1-93-621 is a classic design that has been a favourite among DIYers for years. It offers a generous 19-litre capacity in a lightweight package, making it easy to carry around a job site or store in a cupboard. The removable tote tray is perfect for keeping screws, bits, and small hand tools organised and separate from larger power tools.
Owner reviews consistently praise its toughness and reliability. The metal latch is secure, and the box can be padlocked for added security. While it lacks the modular stacking ability of more expensive systems, for a simple, no-fuss tool box that does everything asked of it, the Stanley 1-93-621 is hard to beat at this price.
DeWalt DWST17820 TSTAK Deep Box
Best Modular SystemPros
- Fully modular with TSTAK system
- Very robust and impact-resistant
- Deep design fits large tools
Cons
- Heavier than basic boxes
- Price is near the £100 limit
The DeWalt DWST17820 is the deep box in the renowned TSTAK range. This system allows you to stack and connect multiple boxes, creating a custom storage tower that is easy to transport. The deep box is ideal for storing larger power tools like circular saws or drills with batteries attached.
Build quality is exceptional, with a tough polypropylene construction that can handle heavy site use. The metal-reinforced latches are strong, and the front-loading design provides easy access. While it costs more than a basic tool box, the modularity and build quality make it a smart investment for professionals or serious DIYers who want a system that can grow with them.
Bosch Professional 1600A002V9
Best Compact PortabilityPros
- Lightweight with aluminium frame
- Compact and easy to carry
- Professional look and feel
Cons
- Smaller capacity than others
- Organiser tray is basic
The Bosch Professional 1600A002V9 is a compact tool box designed for tradespeople who need to carry a core set of tools to different jobs. Its aluminium-reinforced frame provides a good balance of strength and lightness, making it very portable. The box includes a removable insert for smaller items.
Reviews note that it is the ideal size for a drill, bits, a hammer, and a few screwdrivers. The latch is secure, and the overall build quality meets Bosch's professional standards. It is not designed for bulk storage, but for those who value a neat, portable kit, this box is an excellent choice.
Stanley 1-95-621
Best Small Parts StoragePros
- 20 adjustable compartments
- Transparent lid for visibility
- Very affordable
Cons
- Not for large tools
- Dividers can pop out
The Stanley 1-95-621 is a specialist organiser box, perfect for screws, nails, wall plugs, and other small hardware. It features 20 adjustable compartments that can be configured to suit your needs. The transparent lid allows you to see the contents without opening it, saving time on the job.
This box is a great companion to a larger tool box. It keeps small items sorted and prevents them from getting lost. Some users report that the dividers can be dislodged if the box is dropped, but for general workshop use, it is a highly practical and cost-effective storage solution.
DeWalt DWST17821 TSTAK Small Parts Organiser
Best Heavy Duty OrganiserPros
- Fully integrated into TSTAK system
- Very robust and secure latches
- Deep compartments for larger fixings
Cons
- Heavier than basic organisers
- Compartments are fixed size
The DeWalt DWST17821 is the small parts organiser from the TSTAK range. It clips onto the top of the DWST17820 deep box or any other TSTAK unit, creating a modular storage tower. The 15 deep compartments are perfect for storing screws, anchors, and drill bits securely.
Build quality is top-notch, with heavy-duty latches and a clear lid that stays open when required. It is designed for the rigours of a construction site. While it is more expensive than a simple plastic organiser, its compatibility with the TSTAK system and its rugged construction justify the cost for professionals.
What to check before buying a tool box under £100
Before you buy, consider what you will store. A large power tool like a circular saw needs a deep box, while a collection of screwdrivers and pliers fits a standard cantilever box. Check the weight capacity and the material. Polypropylene is durable and lightweight, while metal boxes are heavier but more secure.
Think about portability. Do you need a handle, a shoulder strap, or wheels? For site work, a box that stacks and locks with others, like the DeWalt TSTAK system, is very useful. For home use, a simple box with a removable tray often provides the best value.
Mistakes to avoid when choosing a tool box
A common mistake is buying a box that is too big. A large, empty box is heavy and hard to carry. It is better to buy a box that fits your current tools with a little room to grow. Another mistake is ignoring the latch quality. A weak latch can break, spilling your tools. Always check that the latches are metal-reinforced.
Do not forget about organisation. A single large compartment can become a messy pile of tools. Look for boxes with removable trays or dividers. Finally, check the warranty. Brands like Stanley and DeWalt offer good warranties, which is a sign of confidence in their product's durability.
