Tekton 1-2 in Drive Impact Bit Socket Set, Metric, 9 pcs SIB92103

Tekton impact bit sockets have both a high-visibility size marking and a permanent stamped marking that won't wear off. They're designed for use with both friction ring anvils and detent pin anvils. Our two-piece bit socket design allows us to optimize the steel alloys, heat treatments, and forming processes for the bit and socket separately. This results in a tool that's higher performing and more durable than traditional 1-piece impact bit sockets.
