The Tolsen 10018 dielectric diagonal cutters are designed for safe work under tension, providing essential insulation for electrical tasks. These 160mm tools are crafted from chrome vanadium steel with a black finish and feature induction-hardened cutting edges that can handle wires up to 3mm in diameter. They are specifically suited for cutting copper, aluminum, and other non-hardened wires. To ensure a secure grip during use, the tool is equipped with two-component plastic GRIPro handles that include special stoppers to prevent your hand from slipping.
