Review on Klein Tools 80049 HVAC Tool Kit: Including 3-in-1 Pocket Screwdriver, 8-in-1 Screwdriver/Nut Driver, and Digital Pocket Thermometer - 3 Piece Set by Nick Gathings

This is a great tool for anyone working in the HVAC field. It is very convenient to have a magnetic hex 5/16 and 1/4. The tool for removing the valve insert is also very practical. The other end of the coring tool is a thermostatic flathead screwdriver. Phillips and flathead bits work with any switch or contactor that I've had to change or tighten connections on. There is also a 3/8 screwdriver if you remove the socket to install the attachments. Made of good steel and fairly rust resistant. Fits in your tool bag but more convenient to carry in your pocket. It's not too bulky and has a decent grip until cool oil gets on your hand, at which point it becomes slippery like most hand tools. Excellent purchase. Highly recommended.
