Overview
The WISE × KUROKIN WLB-2300-BG is a professional 9-piece ball-end hex key set designed for fast access and controlled tightening in tight or obstructed spaces. Built for mechanics, installers, and technicians, this semi-long set combines angled-access ball-end tips with a detachable extension handle to improve reach and leverage while maintaining control.
Each hex key is manufactured from high-quality special chrome vanadium steel and precision heat-treated to HRC 60 ±1, delivering excellent strength, wear resistance, and long-term durability. The ball-point geometry allows angled insertion with reduced risk of fastener damage, while the reinforced design improves reliability during tightening and removal. Finished in KUROKIN’s signature black coating with a gold semi-long extension handle, this 9-piece metric set covers sizes from 1.5 mm to 10.0 mm, making it ideal for automotive service, machinery maintenance, and professional mechanical assembly work.
