Klein Tools80049 HVAC Tool Kit with 3-in-1 Pocket Screwdriver, 8-in-1 Screwdriver / Nut Driver, and Digital Pocket Thermometer, 3 Piece

Love the hvac all in one screw driver, really like how the tstat screw driver can be shortened to carry in pocket, thermostat does need a magnetic though

Love the strong magnet. Perfect tool for HVAC.

This is an excellent tool for anyone to have in the HVAC field. It is very handy to have a magnetic 5/16 and 1/4 hex driver. The valve core removal tool is also very handy as well. The other side of the core removal tool is a thermostat screw driver flathead. The Phillips and flathead bit works with every breaker or contactor I’ve had to change or tighten the connections. There is also a 3/8 driver if you remove the bit set sleeve. Made of good steel and fairly rust resistant. Fits in your tool bag but is more convenient to carry in your pocket. Not too bulky and has somewhat decent grip until you get refrigerant oil on your hand then it becomes slippery as most hand tools do. Great purchase. Highly recommended.

I do electrical work not specifically HVAC but, this really works well. I played musical tips to get what I wanted for electrical work and was able to replace two tools with just this one. You need to have this!

Easy to use, strong magnet

Best tool to carry to meet most of the needs of an HVAC technician. Carry this in your meter case or pocket, or your tool pouch. But once you have it, you will have it with you all the time. I have two, they are one of the best Klein tools made. If you do HVAC work, this is 100% for you.

The configuration of this driver is a win for the most part : one nitpicky issue I have is that removal of the bits using your fingers is unusually difficult, actually requiring pliers sometimes to get a grip on the tiny bits. The bits should have jimping.The magnetic dual nut driver gets a thumbs up from me for ease of use and convenience, but that black rubber grip slips when you get onto a stubborn fastner!!Not the only Klein driver I have noticed this issue with lately- it appears that they went with the lowest bidder on that part.

Great tool

good equipment does the job !

Best screwdriver i have ever had. it is pricey and would be better if it was insulated (just to be on the safe side) but as a HVAC engineer this is great

Received the product but missing some of the parts

Bought this back when I was in HVAC/R school and now I’m working in the field. It’s easily one of my most used tools. The 1/4“ and 5/16” magnetic nut driver feature alone was good for me, but the extras also come in very handy. If you’re looking to cut down on having many individual tools in your bag you absolutely need this.

I’ve had this screw driver for a couple years now. I’m a journeyman hvac/r tech of 28 years. I carry this a crescent wrench and meter and I can diagnose most anything. It’s a durable screwdriver. I had to get a new one because mine was stolen by the lil tool ferries.
