Repairs are a necessary part of any home ownership which makes having tools a requirement. A rolling tool bag is the handiest way to maintain control of your tools and still have complete access to the tools when and where you need them. This is of course if we are talking about a small amount of tools.
If you work on vehicles, the rolling tool box or tool chest is rather large and extremely necessary. The sheer weight of the tools is overwhelming with the size and number of tools that you must have and maintain. The rolling tool box must have been designed with a spacious interior for the shape of the tools. You should also look for drawers with small slots for washers, drill bits, tap and die and other things. You should buy a case with enough drawer space that the wrenches and screwdrivers are separate with adequate room. Power tools take up a lot of space so you will need some large drawers.
If you are working with a smaller scaled rolling tool bag, there are several important factors to consider when purchasing which one to buy. The first thing to consider is the wheels. They must be sturdy and large enough to carry a heavy load. Remember, they will be carrying all the weight. Next is the handle. Be sure that it will be able to pull the load without coming apart. Third is the fabric. Canvas is a good choice as is rawhide which is heavy enough to handle just about anything. Plastic is usually not as good a choice since it may crack or break under the stress of heavy loads.
If you are working primarily in the electrical field, your requirements for a roiling tool bag are slightly different. You will need more pockets for the smaller gadgets you use on every job. But you have power tools as well as wire strippers, screwdrivers, large and small. Look for a place to keep your tape clean and neat.
When we had the computer business, our tech people had a rolling tool case that they took with them to all the clients. You can guess that with the small sizes of screws and rubber washers, plus memory chips, switches and plugs, our technicians had to be well equipped on the job. Larger components were carried in the trucks in case they would be needed. There is nothing worse for a customer who is trying to run payroll or some other time critical piece of software to hear, "… sorry, I do not have the piece I need to fix your computer. I'll be back tomorrow . " That just can not be allowed. If you are running a business, give your people the tools they need to be able to satisfy your customers and keep them happy. A wheeled tool case is just one way to help make sure that happens.
If you have a small apartment or a large home, repairs are just a normal sequence of living. Having a well equipped rolling tool box is a smart thing to have handy. Having the tool chest stocked with the correct types of tools will make your life and the repair jobs so much easier.
