Industrial strength performance at an economical price. Durable and easy to use, this tool is designed for smaller shops but has no problem handling high-volume work. In its third version, this constantly improving tool now features a 5/8" round guide for the collar gate housing to slide on, rather than the extractorâÂÂs frame â in addition to proven features like the pressure-gauging T-handle, shaft clamp and permanently fixed collar gate.
