Sonic Ratchets are made from Chrome Vanadium steel polished to a satin finish, while the handles have a comfortable and ergonomic round rubber handle. Sockets are also made from Chrome Vanadium and bits are made from hardened tool steel. The 139-piece Sonic Set includes ratchets and sockets from 1/4”, 3/8”, and 1/2” drive sizes. Each size includes the Sonic Flank sockets that have a reliefs cut in each corner, allowing the socket to actually bite into the flats of the fastener, not the corners. A 1/4” Driver allows for connecting any 1/4” sockets or bits. Specialty bits include Torx, TamperProof Torx, Spline, and IPR.
