The description ((Application: Widely used in Gear shaft, motor shaft, short support shaft, shaft pocket model, miniature axle, model plane, model ship, model cars. )) Rods are bent they wobble if rolled. rises in the middle a 1/16". You couldn't used as Gear shaft, motor shaft, short support shaft, miniature axle. I can use them for my purpose making a small wood turning skew chisel.

8 mm x 200 mm HSS steel rod is horribly bent. It's diameter is correct, but the freaking rod is bent! Freaking useless. This crap needs to be illegal. And Amazon needs to be held accountable also, because it's allowing its third-party sellers to sell crap.
