The new innovative ratchet screwdriver combines direction control and on/off devices together as a whole new all-in-one product. We can simply change its rotation by using the new functionalize device and pull it out to easily release the bits without hands. The great design is not only simple to use but also its function can cover more than 1000kg-cm torsion and has more combinations of tool accessories to play with and be a powerful tool. More than that, the end cap that we have is the bits storage which can be flexible to switch off. The new innovation design is really a super powerful gear and perfectly suitable for professional users.
