HYUNDAI K101 101-Piece Mechanic Tool Set - 1/2" & 1/4" Ratchets - Cr-V Steel

The HYUNDAI K101 101-piece professional mechanic tool set is a comprehensive, heavy-duty portable toolkit engineered for automotive maintenance, fleet servicing, industrial installations, and master trade applications. Every tool is manufactured from high-tensile chrome vanadium steel (Cr-V), providing structural strength, wear resistance, and long-term durability under heavy torque loads.

The set is powered by two fine 72-tooth reversible ratchets in 1/4" (150 mm) and 1/2" (260 mm) drive sizes, engineered with an ultra-short 5° swing arc to service fasteners in tight, obstructed areas. The metric sockets feature the advanced super-lock drive system, transferring contact to the fastener flats to work cleanly on fixings with up to 30% rounding while eliminating damage on new bolt heads. The kit is further equipped with 12 combination spanners, mechanic screwdrivers, ball-end hex keys, a 1/2" breaker bar/flex handle, a 1/4" flexible extension, a 300g machinist hammer, and a wide array of 30 mm driver bits (Torx, Phillips, Pozidriv, Hex, Slotted, and Spline). The collection comes enclosed in a heavy-duty molded plastic carry case measuring 45 x 9.5 x 33 cm with a total weight of 8.1 kg.
