9 piece set is made in the U.S.A. Bit sockets feature SK's high polish SuperKrome finish, which provides for long life and maximum corrosion resistance. Through-hole design makes it easier to replace worn or broken bits. Simply pop the old bit out and insert a new replacement bit. C-Clip retention groove in the hex end provides a secure hold on the bit while in use. Bits are manufactured to rigid standards using high strength S2 steel. High-torque can be achieved with the use of a ratchet, T-handle or spinner handle. With the help of an extension or universal joint, bits can be used in awkward spaces.
