Review on 🔧 Wiha 71397 Hex Metric Insert Bit Set - 2.0 to 6.0mm - 6-Piece by Andrew Roll

They fit snugly (but not very tightly) onto the hex head bolts on my Arrma Kraton 6S RC truck. I bought these specifically for use on RC cars and so far they are working very well. I only used the two smallest bits in the set (2mm and 2.5mm) but they fit the head very well and don't seem to remove heads as I have had problems with cheap Chinese bits in the past. . Despite the affordable price, they appear to be of quite high quality. I'll edit this post later when I have more time to see how durable they are. But my first impression is that these beats are great and all in all a steal. I was pleasantly surprised at how good they are and I will recommend them to my friends who also do RC. I use them with a T-handle screwdriver and a drill with a 6" extension.
