Ko-ken 4725ZB 1/2 Sq. Dr. Ratchet Handle 72 teeth Length 253mm Quick Release Z-series

1/2" Square drive, Z-Series, Standard Length, Fixed Head, 72 Tooth Ratchet with Push Button locking mechanism. The patented design of the 72T incorporates dual pawls. Ko-ken has ensured that their hallmark low backlash and small size are preserved. Through extensive testing over four years, they have achieved a delicate balance of low spring pressure to maintain the low-torque backlash characteristic of Ko-ken tools. Additionally, the finer 72 teeth design provides increased surface area contact with the gear, resulting in a 10% higher torque upper limit.
