This little but versatile tool kit is always essential for your tasks when you work around various sizes and drives of sockets, no matter whether you are a DIYer for home projects or a professional mechanics for auto repairs and tire shop. It serves two major purposes to make your work much more efficient and save you the money and time of buying new tools. <br /> <br /> Firstly, the included 4-piece socket drive converters allow you to switch the drive size of sockets up or down to match your existing ratchets, extension bars or impact wrenches, so that you neither need to change your tools frequently during work, nor need to buy new tools just because of unfit drive size. Secondly, the included 3-piece socket adaptor bits for power tools can quickly convert your corded or cordless power drill and impact driver to an impact wrench or ratchet for working on sockets. <br /> <br /> All the parts in this set are constructed from impact grade drop forged and heat treated chrome vanadium steel with rust-resistant black phosphate finish to provide the tools with superior strength and longevity. They are designed with built-in spring loaded detent ball to lock socket tightly and securely to ensure safety for high torque tasks with impact and power tools.
