SDSF Small Diameter Split Frame Clamshell Pipe Cutters/Bevelers The SDSF is a pipe cutting and beveling tool used by pipefitters and welders in weld preparation for industrial pipe. E.H. Wachs SDSF Small Diameter Split Frames are the smallest and most compact member of the Wachs split frame family of pipe cutters, and are designed for cutting, beveling and counterboring pipe and tubing from .5 inch - 6 inch O.D. (DN15-150). Like all our split frame, clamshell style machines the SDSF Small Diameter Split Frame is designed to “split” in half to fit over inline pipe, or can be slipped closed over open ended pipe. Six models are available in 1 inch (25.4mm) increments, with additional sizes available by special order. The SDSF is ideal anywhere pipe and tube are arrayed in tight places, such as pipe racks, and finds many uses in power generation, oil and gas and shipbuilding. The SDSF operates on air or electric power using standard Wachs motors and adaptors, and is part of a complete system that includes a broad range of tool slides and accessories for maximum versatility. As with all E.H. Wachs products, the Small Diameter Split Frame is built with our legendary quality and durability for years of reliable service.
