ProFlex Torsion Zone Advantage
Klein Tools ProFlex technology represents advanced engineering specifically designed for impact driver applications. The torsion zone creates a controlled flex point that absorbs the shock and vibration generated by impact tools, dramatically extending bit life while maintaining precise fastener engagement. This innovation reduces bit breakage, prevents fastener stripping, and ensures consistent performance under high-torque conditions that destroy conventional bits.
