Ergonomic, hand-held, three-jaw crimp tool with a ratchet mechanism, designed for a fully controlled pressing cycle. It is suitable for use with insulated red, blue and yellow terminals from 0.5 to 6 mm². Longer, formed handles reduce the force required to operate the tool. Worn-out high precision jaws can be replaced to increase the service life of the tool. It is possible to order this tool with a calibration certificate.
