The Spinner Drive is the minimalist solution to have them all - precision screwdrivers, standard screwdrivers and T-Handle screwdriver. You can make easy torque adjustments with ergonomic spinner wheel and smooth ball bearing, and it’s also compatible with universal bits and 1/4 inch bit hex shank. Torque is the force applied times the distance from the axis you are rotating. With the inclusion of the spinner wheel, the diameter of the handle is increased, thus allowing more torque to be generated. In the same compact footprint, you‘ll be able to produce a lot more force compare to traditional screwdrivers of similar sizes. The Standard Edition Plus (Silver / Black) comes with S2 Tool Steel bits with Manganese Phosphate coating that provides extra protection against corrosion and wear over time. The Tough Edition Plus (Black / Gold) comes with SUS420 Stainless Steel bits with Titanium Nitride coating. It combines rust & corrosion resistance and increased edge retention. Both include 20 bits: PH0, PH1, PH2, SL2.5, SL4.5, SL6.5, TR10, TR15, TR20, TR25, SL3.5, SL5.5, PZ1, PZ2, S1, S2, H2.5, H3, H4, H5
