Significant Change In Air Ratchet Design Nestor introduces thier Air Nesco® "No Spread" air ratchets that have a patented "no spread" head design that prevents the ratchet yoke from spreading, resulting in higher sustained torque, durability and protection from dirt and moisture. The specially designed retainer won't slip out and keeps the head assembly tightly contained. Additional features include a built-in power regulator for exact control of motor speed and torque output, an ergonomic contoured comfort grip and 360 degree adjustable exhaust. The air ratchets are available in 1/4" and 3/8" mini and 3/8" and 1/2" full size version.
