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

I bought these for the 2mm and 2.5mm bits that seem to be so popular on my Traxxas Slash RC car. I can put this in a hand/ratchet screwdriver or use it in my 12v Bosch screwdriver for quick but controlled screw removal and replacement. It appears to be very high quality steel and I doubt I'll wear them out before I lose the ones I need. most. I think they could get a lot of use without rounding them up. They fit effortlessly onto the hex head. I don't think I can loosen my screws unless I leave too much dirt or debris in the hex socket and the bit doesn't fit snugly. Recommended by the Traxxas RC Group for use with a low-voltage screwdriver. That's quality.
