Neewer Lightweight Titanium Nitride Coating Hex Driver Wrench 4 Piece Set, Hex Screw driver Tools Kit Set for RC Helicopter (1.5mm/2mm/2.5mm/3.0mm)

I am extremely pleased with these hex wrenches. They are longer than some of the other brands and fit my hand much better than an older set that I had. The handle tube is a little larger which makes it much easier to grip when using. They seem to be pretty well made and you can get replacement shafts (by size) as needed. For the price and quality this is a great set if you deal with a lot of set screws. I use these all the time working with my R.C. vehicles, most of which have set screws. Highly recommended!

I got these to work on my Quads and they do the trick. I'm a huge fan of the length of the shafts on these, make it really easy to work around all the crap I've got attached to my Quads. The sizes of the heads are accurate and pretty strong. I've been using the 2.0mm one several times a day since I received these and there isn't any sign of wearing out yet.

Must have for the 3rd printer or any DIY project. Good handle quality, four different variety of bits, looks really elegant. Robust functional and durable.

Good metric hex drivers for hobby stuff can be hard to come by. I ordered these because they looked similar to some that a buddy has. I'm quite certain he paid about double the cost of these but they don't seem to make them any more. These are good, not great, the hex bit part is a machined piece of rod, hopefully hardened but I can't really tell, put inside an knurled handled. To of mine are 'tweaked' a little bit, meaning if you spin the handle the bit part is 'bent'. Not enough to really be a huge deal but they aren't 100% either. They are also smaller than I thought they would be. I'd say the handles are about 5/8ths of an inch. Something closer to 3/4 would be better. For the price I paid these are acceptable but they are not awesome.

Hefty, solid and work great!

So these will give you a great screwing experience. The hollow core handles keep them light weight. The shaft is replaceable if you damage your head. What can I say these things are just great! My wife made the best comment though “I love that they come in 4 different sizes”. Best little screwdrivers ever!!!

I am not sure if these drivers are actually ti coated. At first they fit the heads of the screws very tightly which was great but after a while they fit a bit less snug. There is nothing on the drivers or the packaging to indicate that they are titanium nitride, just the listing on Amazon. They are inexpensive though and for the price of nicer units you could have two sets of these.

Reason for purchase: I needed these because the provided tools that came with my Bambu Lab printer started to grind down and no longer work. Review: These have done fantastic! Of course, with heavy use they do show wear and tear, but they are infinitely more durable than the one i was using before. They feel great to hold, and have amazing grip. They have a good balance and are very lightweight. For the price, I think they are a good deal.
