Engineered for professional electrician and DIY home improvement applications, this durable hand tool delivers versatile and reliable cutting for BX, MC, AC, and liquid tight 3/8 in. armor conduit. Designed to maximize field efficiency, the tool features an innovative quick-clamp system that automatically adjusts to your specific cable size, locking it securely into position for flawless splitting.

Maintenance is quick and completely tool-free thanks to the specialized thumbwheel design, which allows you to switch out blades in seconds without needing extra tools or equipment. For added convenience, replacement blade storage is incorporated directly into the handle of the tool, keeping your spares safe, clean, and easily accessible exactly when you need them. Choose a tool built for longevity, precision, and ease of use.
