Draper 40 piece professional mechanics bit set. made from SAE 8660 steel. hardened and tempered. consists of hexagon , multi-spline, and torx bits. This has hardly been used, some rust specs on many of the bits as it has spent years in my shed, I would think that these must be 30 year old, in steel box and are probably far better quality than todays kits which probably bend or snap or wear very easily. I doubt that I have used it in the last 25 years.
