For a wide range of DIY car maintenance and assembly tasks, the high-quality Bosch 1/4" and 1/2" Ratchet Set 60-Piece is the perfect companion. The set is made up of high torque 1/4" and 1/2" ratchets, sockets, adapters, extensions, a spinner and bits, all handily stored in a practical carrying case. The 1/2" ratchet allows a powerful torque of up to 768 Nm, while the 1/4" ratchet can be used for high torque applications up to 93 Nm, which is 50% above the ISO 3315 standard. Both ratchets have a fine 72-tooth powder metallurgy gear that allows a 5° working angle for better power transmission, even in hard-to-reach areas. For fast directional change, an intuitive switch is easily accessible on the neck of the ratchets. The ergonomic ratchet handles have soft-grip areas for added control and comfort. The ratchets conform to the ISO 3315 standard.
