Koken 3725ZS 3/8 Sq. Dr. Ratchet Handle 72 teeth Length 100mm Z-series

The Koken 3725ZS Ratchet Handle is the newest iteration of Koken's Z-Series, combining what people already loved about these ratchets with entirely new strengths. In the past the Z-Series has been known for its very low backlash, small head sizes, and high torque ranges. The new 72 tooth ratchet is designed without compromising on the traditional strengths of the Z-Series. The 72 tooth ratchet moves 5°/click and utilizes a single spring. Expertly crafted to perfect the low spring pressure needed to maintain Ko-ken's hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear and has a 10% higher torque upper limit compared to legacy products.

Product Video

Ko-ken ratchets are known for their very low backlash, small head sizes, and high torque ranges. We designed the new 72 tooth ratchet without compromising on our traditional strengths. The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10°/click. The new 72 tooth ratchets move 5°/click.
The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design. The dual pawl 72 tooth design utilizes a single spring. We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken's hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit.
