Gardner Bender’s wire strippers deliver what most contractors actually need — multi-function tools that strip, cut, crimp, and re-thread bolts without breaking the budget. The GS-366 model shows exactly what these tools are about: hardened steel blades that handle real work, not plastic handles that crack after a season.
Built for Versatility, Not Flash
The GS-366 packs serious capability into a basic package. Strips 8-20 AWG solid and 10-22 AWG stranded wire, crimps 10-22 AWG terminals, and cuts or re-threads five different bolt sizes. That’s the difference between carrying one tool or five in your pouch.
Hardened steel blades mean these cut clean through copper and aluminum without deforming. The integrated wire strip length gauge and pliers-style nose for pulling and looping wire turn this into a proper multi-tool, not just a stripper with delusions.

4.0-4.5 star typical ratings tell the real story. These aren’t Klein or Knipex — and they don’t pretend to be. Klein Tools 11063W is more professional grade and precise. Gardner Bender’s wire strippers target contractors who need functional tools.
The trade-offs are honest. Basic handles instead of ergonomic grips. Manual selection required rather than automatic stripping. But for residential and commercial electrical wiring projects, automotive wiring repairs, HVAC system installation, and general DIY electrical projects, these tools deliver what matters.
Perfect for the contractor who needs multiple tools — one in the truck, one in the shop, spares for apprentices. Losing one doesn’t derail the workday.
Installation Reality
Select AWG slot, squeeze, and pull for wire stripping. Use jaw, insert terminal/wire, and squeeze for crimping. Thread bolt into hole and squeeze for bolt cutting. No learning curve. No special technique. Just basic mechanical action that works every time.
The 0.3 oz weight makes these disappear in a tool pouch. Light enough that carrying multiples doesn’t add noticeable weight — important when you’re climbing ladders all day.
Frequently Asked Questions
Q: How does the GS-366 compare to Gardner Bender’s automatic strippers?
The GS-394 is automatic and faster for stripping but lacks some multi-tool features. Choose the GS-366 when you need crimping and bolt cutting capability, not just fast stripping.
Q: Can these handle both copper and aluminum wiring?
Yes — designed for both copper and aluminum conductors. The hardened steel blades cut clean through either material without crushing or deforming the wire.
Q: What’s the real difference between these and premium brands?
Build quality and precision. Klein is more professional grade and precise. Gardner Bender wire strippers handle 90% of electrical tasks. Save the premium tools for precision work.
Q: Are these suitable for commercial job sites?
Applications include residential and commercial electrical wiring projects. The one-year warranty reflects basic construction, but the hardened steel holds up to daily use. Many contractors buy multiples and treat them as consumables.
