*STEEL ALLOY MATERIAL – extremely long-lasting and durable.
*105 DEGREE DESIGN – excellent for working in confined spaces and enhancing the power of a cordless screwdriver.
*1/4″ HEX SHANK – can be quickly swapped out for drills, drive chucks, and wrenches, among other applications.
*360°PARALLELLY ADJUSTMENT – Hand drill and manual wrench can be connected together.
Built-in magnetic socket holds standard hex drilling and drive bits in place and prevents them from falling out.
Note: Despite the fact that these tools have excellent torque rotation capability, they are incompatible with the drivers of high-speed and high-power drilling rigs.
It appears to be a China-made item because the longer one broke off the first time I used it, but the smaller one worked perfectly.
