Precision Measuring Suite: Unlike the 134 or 168-piece sets, the GTT-178 includes industrial-grade measuring tools such as digital calipers, micrometers, and angle finders, making it ideal for engine blueprinting or machinery calibration.
Triple-Drive Socketry: Provides full coverage across 1/4″, 3/8″, and 1/2″ drive systems, ensuring you have the right scale of tool for everything from dashboard electronics to heavy chassis work.
Specialized Wrench Groups: Includes Half-Moon (Starter) wrenches for curved access, Flare Nut wrenches for hydraulic lines, and Gear-Ring wrenches for rapid ratcheting in tight spots.
L-Type Hollow Sockets: Features a unique tray of L-type deep hollow sockets, which are invaluable for working on long threaded bolts where a standard deep socket might bottom out.
The Hans GTT-178 (Great Tool Trolley Group) is a high-performance, 178-piece professional tool collection. It is one of the most advanced sets in the Hans lineup, moving beyond standard mechanical repairs to include precision measuring instruments and specialized wrenches for heavy-duty industrial and automotive calibration.
