What to check before buying a crimping tool
Before purchasing a crimping tool under £100, consider the type of terminals you will be using. Ratchet crimpers provide consistent pressure and are recommended for most applications. Check the capacity range of the tool to ensure it covers the wire gauges you work with. Build quality and ergonomics are also important for comfort during extended use.
Mistakes to avoid when choosing a crimping tool
A common mistake is buying a non-ratchet tool for frequent work, as it can lead to inconsistent crimps and hand fatigue. Another error is ignoring the minimum wire size capacity, which can prevent crimping small terminals. Always verify that the tool matches the terminal type you intend to use, such as insulated or non-insulated connectors.
