I purchased the Fedus rj45 crimping tool kit (Combo-3) for my networking projects. This kit includes a passthrough crimping tool that handles Cat5 to Cat8 cables, 25 rj45 connectors with boot covers, LAN tester, cut & strip tool, 25 cable ties, and a kd-1 punch down tool. Everything you need for Ethernet cable termination and testing is included. Very solid build quality and easy to use — excellent value for technicians and DIY setups.
