KLEIN TOOLS32787 64-Piece Micro-Ratchet Bit Precision Driver Set with Modular Case, Magnetic, Precision, Standard Bits and Nut Drivers

I found this kit to be extremely useful. The ability to switch from the Klein 3.5 mm precision bits to standard 1/4 inch (6.5 mm) bits is fantastic. The included nut drivers work extremely well, but I do wish they had the option for metric nut drivers as well. The (screw) driver handle works well and is a size that fits perfectly between my Klein pocket precision screwdriver and my full-size 11-in-1 ratcheting screwdriver and gives me a full range of options with these bits and another security bit set I have in metric, as well as my Klein flip socket sets in both metric and SAE sizes. The ratchet operation is smooth and uncomplicated, and the case is a fine example of engineering in itself - Way to go Klein Tools! I would only make one suggestion, that being that the included 1/4 inch hex adapter for using the more common 4 mm precision bits is made of some non-magnetic alloy and has no internal rare earth magnet to retain inserted bits; this would be a simple fix by using ferrous metal for the adapter or by increasing the adapter length by 2 mm and installing a small 2 x 4 mm magnet - a small complaint, but would prevent bit loss (Klein uses proprietary 3.5 mm precision micro bits vs. the more common 4 mm bits found in other sets). Overall, this is an extremely useful and versatile kit that I highly recommend - just got to love quality, precision, and cross-compatibility in the tools you buy.

I have this set both at work and at home. I have used them daily for over a year now and they are still in amazing shape. It's a well thought out kit that has most of what you will need for all kinds of repairs and assemblies. My only complaint is I wish it had pass through sockets instead of nut driver bits. But they have a tool set that has those so I just got that one too.

Best set I currently have on hand. I use it frequently must have took set

FANTASTIC for smaller (10th scale or less) RC cars and electronics! I do recommend and would certainly buy it again.

Great set of precision and security tools. Value for money is definitely there when compared to more expensive alternatives. Easy to use with the bits being secured well and smooth to change out. excellent tool kit for a laptop bag or EDC kit.

Like all Klein, quality

My new favorite set for IT repair! It could use a few more security-type bits tho. The price is a little high too.

The only screw drivers that have lasted more than a year or two are now 50 years old. Any new ones and the blades quickly round or warp. Finally, I found this driver. It has small and medium size bits. When I say small, I mean small enough to fix your kid’s glasses. Another great feature is that it can lengthen to almost twice its size. Very handy and very grateful for this feature. The bits are standard size and also fit my Dewalt driver. The bits seem like they will not last 50 years, but since standard size, I can easily replace. I am hoping that this is the last driver that I will ever purchase. I do have a larger similar driver when I need more torque. I haven’t purchase something this well designed and of high quality in quite some time. Gives me hope that maybe some companies still care about providing high quality products.
