Gardner Bender GST-70M Wire Stripper/Crimper, 8-20 AWG, Voltage Sensing

The Gardner Bender GST-70M Circuit Alert is a four-in-one electrical tool that combines wire stripping, crimping, bolt cutting, and voltage sensing in a single device. This patented tool features a snap-in sensor that detects AC voltage without contacting live wires, helping you work safely around electrical circuits.

Whether you're working on residential wiring, electrical installations, or general circuit work, this multi-function tool handles several essential tasks. The built-in voltage detector identifies energized circuits before you begin work, while the sharp cutting edges, crimping function, and bolt cutter handle a range of electrical fastening and preparation tasks.

Features and Benefits

• Voltage Detection: Built-in sensor detects AC voltage from 50–600V AC without direct contact with live wires.
• Wire Stripping: Cleanly strips 8–20 AWG wire with sharp double-bevel cutting edges that ensure precise cuts every time.
• Bolt Cutting: Cuts small bolts from 4–40 to 10–32, useful for fastening tasks during electrical work.
• Crimping Function: Crimps terminals and coaxial connectors from 10–22 AWG, creating strong and lasting connections.
• Cushion-Grip Handle: Comfortable grip for handling the tool during use.
