Klein Tools K12035 – Frequently Asked Questions

1) What wire sizes will the Klein K12035 wire stripper handle?
The Klein Tools K12035 strips 8-18 AWG solid and 10-20 AWG stranded copper wire. Note the split: solid stops at 18 AWG, so 20 AWG thermostat or low-voltage solid conductors fall outside its stripping holes even though 20 AWG stranded is covered. For standard branch circuit work in 12 and 14 AWG solid Romex, it sits right in the middle of its range.
2) Is the Klein K12035 wire stripper insulated for live electrical work?
No. The K12035 is not insulated, so it must not be used on energized conductors. It's a general electrician's stripper for de-energized work. If you need protection on live circuits, you want a tool rated and marked for 1000V insulated use instead.
3) Can this Klein stripper cut Romex and shear screws, or do I need separate tools?
It does both. The shear cutting knives handle copper wire and larger material including nonmetallic sheathed cable, and there are shearing holes for 6-32 and 8-32 machine screws, the two sizes used on device mounting and cover plates. There's also a wire looping hole for forming terminal hooks, so one tool covers strip, cut, shear and loop on a device rough-in.
4) How big and heavy is the Klein K12035 stripper for a pouch or tool belt?
Overall length is 8.41 inches (21.4 cm), width 2.25 inches (5.7 cm), height 0.53 inches (1.4 cm), and it weighs 9.6 oz (272 g). That's a full-size heavy-duty tool, longer and heavier than a compact stripper, so it eats a proper pouch slot rather than a shirt pocket. The extra length is where the leverage for shearing screws and cutting NM cable comes from.
5) Will this Klein stripper work for one-handed use up a ladder?
It has a hold open spring, so the jaws return open on their own after each cut or strip. That's what makes repeated one-handed stripping on a ladder or inside a panel practical, and it cuts down hand fatigue over a long day of terminations. The Klein-Kurve comfort grip handles are textured for grip with gloves on.
6) Is the Klein K12035 tough enough for daily commercial and industrial use?
It's forged steel, which Klein rates at four times the strength of their traditional wire strippers, and the joint is hot riveted so the blades don't separate or develop wobble with use. For an MRO crib or a contractor standardizing a crew's pouches, that's the construction difference between this and a stamped-steel stripper.
7) Can I use the Klein K12035 for low-voltage, HVAC control, or automotive wiring?
Yes for stranded down to 20 AWG, which covers most HVAC control wire, automotive circuits, and low-voltage runs. Solid conductors only go down to 18 AWG, so 20 AWG solid thermostat wire is below its range and you'd need a finer stripper for that. The knurled plier tip is useful for pulling and twisting those small conductors.
8) What model number and color should I order to match what my crew already carries?
The part number is Klein Tools K12035, with blue and gray comfort grip handles. If you're restocking to match existing tools in the fleet, that MPN is what to reference on the purchase order.
