The 72 tooth Mach series 3/8 inch drive ratchet is built for speed turning sockets 16x's times more efficient than a regular ratchet with a swing arch of 60 degree. The Mach series 3/8 inch drive ratchet combines the speed of a "Push Twisting" screwdriver, a ratcheting screwdriver and the higher torque and access of a ratchet assembled together into one tool. The Mach series ratchet head pivots 180 degree for better access for hard to reach fasteners and for higher torque fastening applications. Helix drive shaft locks into position transforming the Mach series ratchet driver into a standard socket wrench. Also reverses direction at the flip of a switch with forward and reverse indicators marked on the handle.
