Good tools for what I need them for

Great to use such high-quality tools. I was happy to throw away my China made tools that I had used before.

Typical Klein quality tools. Not the least expensive out there, but if you use your tools daily these are a bargain. They also have a lifetime warranty - no questions asked replacement. This set has a wide range of sizes, comfy handles that allow a solid grip, and both labeled and color-coded as to size for a quick grab.

They're Klein, and that typically means quality tools and this set doesn't disappoint. I keep the set in my Veto MCT bag which lives in my van and I only pull it out on big jobs. I think what sets Klein apart is the color and sizes on the handle tips, makes them easy to identify and pull from the bag. Quality is just superb and I like that the shank is hollow. Couple weeks ago was working in a cooler and had to replace a little evaporator blower fan. I grabbed the MCT bag and used this driver set because nothing else was going to make quicker work of it than these. The set offers up the majority of sizes that I'll ever run into so for me it was perfect. If your looking for a great starter set, new to the HVAC trade like I was when I purchased this is a great set to go with. Keep in mind this isn't the set with the magnetic tips, this is the hollow shank type which is very useful for removing nuts on bolts that are very long.
