  • Klein Tools 80013: My Go-To Crimping Kit Review

    BySteve

    After twenty years pulling wire in attics and crawl spaces, I’ve learned that most combo tool kits are garbage. The Klein Tools 80013 changed my mind. This two-piece setup pairs an automatic wire stripper with a ratcheting crimper, and both actually work like they’re supposed to. The stripper handles 10-22 AWG without mangling the copper—something I deal with daily on thermostat and control wiring. The ratcheting crimper gives you consistent pressure every time, which means reliable connections on insulated terminals. No more guessing if you squeezed hard enough. I’ve been running this kit for eight months now, and it’s held up through residential installs and commercial service calls. Not the cheapest option out there, but it’s Klein—you’re paying for tools that won’t fail when you’re three jobs deep on a Friday afternoon.

  • My Go-To Klein Crimper for Data Cable Work (47 characters)

    BySteve

    After years of running thermostat wire and ethernet cables for smart HVAC systems, I’ve gone through my share of crimpers. This Klein VDV226-110 has become the one tool I reach for every single time. What sets it apart isn’t just the ratcheting mechanism—though that does guarantee consistent crimps—it’s how it handles pass-thru RJ45 connectors without fighting you. I’m terminating Cat5e and Cat6 cables weekly for zone controls and WiFi thermostats, and this thing just works. The built-in stripper and cutter mean I’m not juggling three separate tools in a cramped mechanical room. It’s not the cheapest option out there, but when you’re 20 feet up on a ladder, you want something reliable in your pouch. Klein built this for people who actually use their tools daily, and it shows.

  • Klein 3005CR Crimper: My Field-Tested Review (47 characters)

    ByMike Izzo

    I’ve put the Klein 3005CR through its paces on dozens of service calls, and it’s become the crimper I actually reach for. After years of fighting with cheaper tools that either couldn’t grip small gauge wire properly or left me with inconsistent crimps on thermostats and control boards, this one just works. The ratcheting mechanism won’t release until you get a complete crimp—no more callbacks because a wire pulled loose. What really sold me was using it in a cramped air handler where I needed to terminate four 18-gauge wires for a new zone controller. The tool’s compact head fit where my old crimper wouldn’t, and every connection was solid. It’s not the cheapest option out there, but I’m done buying tools twice.
