Wera 8100 SC 2 Zyklop 1/2 inch Drive Speed Ratchet Set 37 Piece Author admin Date June 24, 2023 Wera 8100 SC 2 Zyklop 1/2 inch Drive Speed Ratchet Set – 37 Piece. Used for a couple of times probably, but I still managed to lose one bit TX 30 x 35, so that’s the only downside. Other than that – perfect condition.
