Felo Smart Evo set is both an interchangeable screwdriver set and T-handle set, the innovative design allows the user the switch between the two options while still utilising the same handle. This functionality is ideal for when increased torque is required, the blade is locked in position and can be easily adjusted when required and then locked back into place. The set comes with 12 double ended extra length blades, effectively providing the user with 24 different variations of screwdrivers and 24 T-handle options. The blades can also be used with power tools, and this provides yet more functionality, supplied in a heavy-duty impact proof case.
