Wiha 71397 6 Piece Hex Insert Bit Set - Metric

Wiha makes the best quality bits that I have ever used. They are precisely machined and made of a very high-quality quality steel. I don't mind paying more for bits that last through more than just a few uses. I got so sick of paying for bits that were pretty much shot after one or two uses. That's when I decided to pay a more for a more well-known brand, and I'm so very glad I did. They fit extremely well in the driver chuck and in the fastener. The stock picture doesn't show it, but mine came in a good quality 6-hole bit rail/holder. Don't hesitate to buy this brand if you're looking for a better bit.

These fit snug (but not super-snug) into the hex screws on my Arrma Kraton 6S RC truck. I bought these specifically for use on RC cars and so far they are working out really well. I've only used the two smallest bits in the set (2mm and 2.5mm) but they fit the heads really well and seem like they wont strip out the heads like I've had trouble with using cheap-o Chineseium bits in the past. Dispite being affordable these seem to be fairly high quality. I'll edit this post later once I've had more time to see how durable they are long-term. But my first impression is that these bits are great and a killer bargain all things considered. I have been pleasantly surprised by how good these are and I will recommend them to my buddies who also run RC. I use these with a T-handle driver and with a power drill with a 6" extension.

These are really high quality bits. The sizing is perfect, they fit in the size like they should. They don't strip the bolts. I actually lost these in my house since they're so small and I will be buying another set.

I've had this set for around 2yr now. It lives in a little sleeve inside my main general-purpose bit case in my main tool bag, and therefore gets a lot of use.This is a tremendous bit set. The quality and fitment it top notch. If you've made it to the review section of a Wiha bit set, then you probably already know what you're looking at. Just buy it already. If / when I do eventually break or lose one, I'll come back here and buy the same set immediately!

Great bits come with a little plastic sleeve

1st set had 2 3mm bits. Amazon replaced it. 2nd set was correct. Fit is good. Not sloppy like cheaper ones. Important on smaller bits.

I'm moving to a new apartment, and so am either assemling or dissasembling whole lot of furniture. While manual Allen wrenches are fine, I'd still be cranking right now if I couldn't pop these miracle bits onto my drill. Seriously, these bits have already saved me hours of work, and I still have a full bed and desk to take apart. The work is still arduous, but these little bits make it doable.As for the bits, they're very sturdy and well made. I've used them both my electric drill and power screwdriver. The bits fit perfectly in their little utility set for storage. Definitely a treasure for my toolbox.

Would purchase again.
