Trav-L-Cutter Wachs Trav-L-Cutter, or "Travel Cutter," is a portable inline pipe and pipeline cut and bevel milling machine with 6in-48in (DN150-1200) included capacity. These machines feature atmospheric anti-corrosion package with stainless steel components and special finishes. When E.H. Wachs® is mentioned, the product that often comes to mind is our famous Trav-L-Cutter. Secured to the pipe by a special tensioning/drive chain, the Trav-L-Cutter drives itself around the pipe as it simultaneously cuts and bevels, providing a machined surface ready for welding. It's designed for severing and beveling all common pipe materials, wall thicknesses and sizes from 6 inch O.D. (DN150) on up. The Trav-L-Cutter® special milling blades, with standard weld bevel capabilities of 30 degree & 37.5 degree, remove .188 inch (4.8mm) of metal during operation, leaving the pipe ends with a fine milled finish and no heat affected zone (HAZ). Our best selling Model E uses a powerful pneumatic drive motor, and can be powered by most industrial air compressors. The Model HE utilizes a powerful, sealed closed loop hydraulic drive system, ideally suited for hostile environments or for use underwater.
