Multi-Tool for Wire Work

The GS-366 combines cutting, stripping, crimping and bolt rethreading in one hand tool for residential electrical tasks. Hardened steel blades handle copper and aluminum wire while cushioned grips reduce fatigue during repeated use. It covers solid wire from 8 to 20 AWG and stranded wire from 10 to 22 AWG. Insulated and non-insulated terminals in the 10 to 22 AWG range are crimped with the same jaws.

Sustained Use Durability

Hardened steel cutting edges keep their geometry through long sessions of cutting and stripping without dulling quickly. The ergonomic cushioned handles absorb pressure so that repeated crimping and bolt cutting stay comfortable over an entire job. Bolt-cutting stations for 4-40, 6-32, 8-32, 10-32 and 10-24 threads remain precise after many cycles. One-year parts and labor coverage backs the build quality.

Wire Gauge Range Decides Fit

The single specification that determines whether this tool fits the job is the supported wire gauge window: 8 to 20 AWG solid and 10 to 22 AWG stranded. Buyers who need to strip or crimp outside that range cannot use this tool for those conductors. The bolt-cutting stations are limited to the listed thread sizes and will not accommodate larger hardware.

Questions about this item

How much hand force is needed to cut or crimp with the GS-366 all day?

The ergonomic cushioned handles reduce grip fatigue during repetitive cutting, stripping and crimping tasks. Hardened steel blades keep cutting effort low over long sessions.

Does the GS-366 need a separate die set or calibration tool to crimp 10-22 AWG terminals?

No. The tool has built-in crimp nests for 10-22 AWG insulated and non-insulated terminals, plus bolt-cutting stations for 4-40 through 10-32 threads.

Can the GS-366 strip the older 8 AWG solid wire still found in some panels?

Yes. The stripper section handles 8-20 AWG solid wire and 10-22 AWG stranded wire, covering legacy 8 AWG solid conductors.
