6-piece set includes three pry bars (1/4 in, 3/8 in, 1/2 in) and three drive extensions (1/4 in, 3/8 in, 1/2 in) for automotive, mechanical, and industrial repairs. Robust construction: made from high-strength alloy steel and forged with hardened chrome-vanadium steel for durability in demanding environments. 180-degree rotating head: full 180-degree rotation to reach tight spaces and apply torque from multiple angles for maximum efficiency. Ergonomic design: designed for user comfort; chrome-vanadium steel construction reduces fatigue while delivering optimal turning torque for extended use. Compatibility and application: sizes match common sockets (1/4, 3/8, 1/2 inch); three drive extensions extend reach and adapt to different fasteners. Use scenarios: - Automotive repairs in cramped engine bays to pry panels or position components. - Mechanical assembly in tight spaces where access is limited. - Industrial maintenance requiring leverage and multi-angle torque.
