Handheld crimping tools usually have plastic or rubber grips on the handles for added comfort. On cheap crimping tools, this can be quite thin and prone to splitting. Better-quality models frequently have thicker padding and better ergonomics, offering a more secure grip. DIY and hobby users will often try to find a single tool for multiple applications. This is particularly true when dealing with specialist connectors.
Contractors often buy several different crimping tools, finding the efficiency and reliability of having the right tool for the job more than makes up for the extra expense. Using the wrong type can result in poor connections that eventually lead to a breakdown. In factories and other high-productivity situations, automated machinery is used.
For example, a hammer crimping tool is often found in auto shops for refitting battery cables. If the same task had to be undertaken several times a day, a hydraulic crimping tool would make more sense. Similarly, a basic handheld crimping tool might suffice for folks who tinker with electrical devices as a hobby. A pro who does the same types of repairs on a daily basis would choose a ratcheting model so every crimp had the same pressure applied, every time. These also release automatically, increasing productivity.
Hydraulic and hammer crimpers are heavy-duty tools that can handle the largest of wire gauges. The former is limited by the die sizes available, the latter by how much physical force can be applied. With more general electrical projects, such as repairing household appliances or electronic apparatus, there are a number of different profiles.
These include hex, indented, circular, B-Crimp, and others. The profile defines how the crimp closes around the cable, so choosing the right type of jaw is vital in providing secure connections. Most handheld crimping tools will offer a range of cable gauges and should make clear the type of profile they provide. Electrical crimp connectors come in dozens of different materials and styles: nylon, PVC, non-insulated, insulated, heat shrinkable, ring, spade, Faston, Lucar, Shur-Plug—the list is extensive.
Many of these descriptions have little impact on the type of crimping tool used, as they define the type of connection being made between two components. However, some types of crimping tools work better with nylon than PVC, for example, making it important to understand the specification of the connector to select a suitable crimper.
Often the manufacturer makes this easy, not just by giving clear definitions but also by color coding the jaws so you have rapid visual identification. Even basic models will handle a variety of cable and connector diameters.
Better-quality tools may offer replaceable jaw sets, which give you the opportunity to handle three or four times as many sizes and potentially different types of connectors as well. Wire stripping is a necessary part of any crimping operation, and some tools incorporate blades for this purpose. Cutters for trimming cable to length may also be included.
Crimping tool kits may extend this further with the addition of cable testers or the terminals themselves. The criteria detailed above went into the selection of the following tools, along with the precision and durability of each product. Busy professionals and enthusiastic amateurs will both appreciate the ease of use, repeatable performance, and excellent value of this Titan wire crimping tool.
The double crimp die provides extra cable security. Jaws are color-coded for rapid identification and high productivity. At 7 inches long, this versatile, well-priced device fits easily into a tool box, yet it provides sufficient leverage to apply plenty of force when crimping.
These relatively inexpensive tools work well for in-the-field use and repairs, can be used in confined spaces, and enable wire cutting and stripping as well as crimping of terminals.
Companies with medium output will want to seek out models that are more ergonomic and rugged—often with longer handles and ratcheting capabilities for enhanced quality control and ease of use—such as the Service Grade Crimp Tool from Molex. Above: The Service Grade Crimp Tool from Molex features a ratcheting mechanism to ensure even pressure and full range of motion for a proper crimp.
Wire gauge is another top consideration. Also important is the type of terminal being crimped because each type of terminal has a specific crimp profile. Insulated or Non-Insulated. Be sure to pick the right crimper for use with an insulated or a non-insulated terminal. Crimpers for insulated terminals have rounded jaws designed to avoid damaging the terminal insulation. Using an uninsulated crimper on an insulated terminal could damage the insulation sleeve or lead to an under crimp or an over crimp.
Open or Closed Barrel. Terminals typically come in two main types—open barrel or closed barrel. Closed barrels are the most common type seen in the wire terminal market.
They come in insulated and non-insulated varieties, quick connections, and many shapes and sizes. Oval or hexagon stye crimps are typically used for closed terminals. Open barrel styles, in contrast, provide the best resistance to vibration and corrosion and are commonly used in automotive wire harnesses and high-volume applications. Manufacturer Specifications.
If you must comply with UL or other guidelines, it is especially important to adhere to manufacturer crimp tool specifications. A multipurpose crimper will typically not be acceptable. Draper 2. EGA Master 8.
