The terminal decides the die and nothing else does. An insulated spade, a bare butt connector, an RJ45 plug and a coaxial connector all need a differently shaped die, and a crimp made in the wrong one looks finished and pulls apart under load. A failed crimp also fails intermittently rather than immediately, which makes it hard to find later.
Ratchet action is what guarantees the crimp is completed rather than half-made. The tool will not release until the full stroke has been travelled, which removes the judgement that causes most failed crimps on a hand-squeezed tool. It also means every crimp on a run is made to the same compression rather than varying with fatigue.
Multi-way crimpers carry several die shapes on one jaw at 215mm and 240mm, which suits general electrical work where the terminals vary. A dedicated ratchet crimper at 220mm does one family properly and is the better tool where the same terminal recurs. Die shapes are stated per tool rather than being judged from the jaw photograph.
Data and coaxial connectors sit apart from electrical terminals entirely. An RJ45 ratchet crimper seats eight contacts through the insulation at once, and a coaxial crimper works to the connector's own specification. Combined stripper and crimper tools at 210mm cover both stages. Send the terminal to 07754288583 on WhatsApp. Terminal kits supplied with a crimper cover both the tool and the connectors it forms. Coaxial connectors also vary by cable type, so the crimper is matched to the connector rather than to the cable alone.
