It Really Is A Heavy Duty Multi-Nut Driver.
When I entered HVAC class, this was the first Klein tool that I bought. I thought it was great to have 7 nut divers in one tool and it is certainly very well built. What I didn’t understand at the time was that most Residential HVAC Techs use mostly two sizes 1/4” and 5/16” and occasionally a third size 3/8” most of the time. Also nearly all Techs use a Drill or an Impact for nuts. So, I never used it in the field until I moved to commercial units and HVAC Maintenance. Then it became my everyday carry for a while. I replaced it with the Klein Tools 32900 7-in-1 Impact Flip Socket with Handle so I could use the sockets with my Impact Driver as well as the Handle if I wanted to turn them by hand. If you’re creative you can use the 32807MAG with an Impact to at least break loose rusted nuts on equipment, not easy but it can be done and with the heft that the 32807MAG has, short bursts with an Impact won’t hurt it. Of course if you have an adjustable wrench, the 32807MAG has a six sided section on the handle that is perfect to add leverage to manually break loose nuts.

        Minimize clutter
        [This review was collected as part of a promotion.] Great nut driver saves a lot of room in your belt magnets and holding ring keeps the nuts in place nice and firm so they don't drop out, handle is comfortable like all klein drivers and I like the fact sizes are lazer engraved
          Awesome tool
          [This review was collected as part of a promotion.] I've been an electrician for 4 years and this nut driver is an awesome addition to my tool bag I use it everyday from tightening 7/16 nuts to installing 5/16 ground screws to boxes

            Great tool but...
            [This review was collected as part of a promotion.] I love this nuts driver. It has almost all the sizes you will need. However, the quality or materials used for the handle isn’t that great. It cracked after a few months light use.

                heavy duty. questionable
                I like this nut driver for its versitlity. As well as the difference between this and carrying all those nutdrivers size in my tool bag. Its been quite useful but the other day I dropped it. Which resulted in it exploring at the handle.

                  Tool is made extremely well and is very durable. It takes the place of 6 different nut driver's.

                  I do like this tool,but only 3stars. The first time I used it the magnetic ring broke. This happened during normal use. This is a good tool if you only need to use once in a while. Spend a little more and get the whole set if you use drivers everyday.
