This Wiha Torx bit set offers a versatile selection of Torx head bits for use with 1/4" universal hex drivers. The set includes T5, T6, T7, T8, T9, T10 torx bits. Torx bits offer a 100% improvement in drive performance over other bit driver systems, virtually eliminating screw head cam-out. Each bit has been through hardened for the best possible wear resistance.
Works very well and well worth the price imo.
You can always depend on Wiha to make quality torx bits. Used these for my knife maintenance and hold up better than any other bits I've own.
