  • Go-to tool for lots of projects
Style: 8-in-1
This is an excellent driver for most appliance repairs. Not just HVAC. The magnet stays just right at 1/4 and 5/16. Strong and steady. I replaced the Schrader with a 1 and 2 Combo Bit for electrical. Perfect

  • HVAC tech screwdriver
Style: 8-in-1
Kills the HVAC game. Has everything you’ll need to hvac. I’ve had about 3 of these and keep buying them as they get left on job sites. If you need things like a square bit or torx then get the 16 in 1 impact rated screw driver.

  • Almost good

Has almost everything I wanted, except the schraeder valve tool. Bought a replacement bit with smaller phillips and flathead to replace it. Now it is my goto combo screwdriver and I have tried almost all of Kleins combo screw drivers.
