The 700 Series super-cushion (gel-grip) screwdriver features an innovative gel-filled handle that provides elasticity when gripped for maximum comfort. Its unique layered cross-sectional structure is designed to provide excellent torque transmission; especially in applications where a large load is gradually applied on the palm such as when working with long wood screws. Other features include a fully hardened chrome vanadium steel shank, a black chrome plate finish, and magnetized precision machined tips for accurate fastener fit.These durable gel-grip handle screwdrivers are designed for professional use such as construction, electrical, air-conditioning, water works, or for general use. Also, the cross-point models are recommended when working with JIS (Japanese Industrial Standard) screws.
