Professional bit set from LAOA

A high-quality set of bits with a 3/8" (9.5 mm) connection designed for use with ratchet and impact wrenches. The bits are made of reinforced chrome-vanadium (CR-V) steel, which provides high rigidity along with flexibility that prevents breakage under high torque.

Industrial durability: The bits undergo rigorous heat treatment to obtain an optimal combination of strength and wear resistance (high hardness and good toughness).

12-rib (Spline) structure: Specially designed for maximum grip on multi-rib star-head screws, which prevents slipping and keeps the screw head intact.

Clear size marking: Each bit is laser engraved with the size and LAOA brand for quick and easy identification in the toolbox.

Intended use: Perfect for automotive mechanics, heavy machinery maintenance and infrastructure work.
