With the Knipex 97 52 09 crimping pliers, you achieve secure, solderless electrical connections on heavy-duty power cables. The tool features 3 fixed precision profiles designed for insulated and non-insulated wire ferrules of 10 mm², 16 mm², and 25 mm². High leverage transmission reduces required hand force by up to 30% compared to conventional tools. For handling larger conductors, the 250 mm length and non-slip plastic handles enable comfortable, controlled two-handed operation. The unlockable ratchet mechanism and factory-calibrated crimp pressure ensure the pliers only open once full compression is achieved, guaranteeing consistent, professional results in every control panel.
