This "spinner" driver from Beta Tools features a sliding T-handle that can be removed for compact storage. It also lets you turn the T-handle into an L-handle for maximum torque, then back to a T-handle for quick fastener spinning. All three ends (extended end plus both ends of the handle) have the same T7 size male Torx drive. Sold individually.
This wrench is also available as part of the Beta Tools 951TX/S13 13-Piece Sliding T-Handle Torx Drive Wrench Set (Part No. BT-009510863).
