INTSUPERMAI Portable Line Boring Machine

Designed for on-site repair of excavators, cranes, and loaders, this portable boring machine processes holes from 45mm to 180mm diameter with a maximum travel of 380mm. The 1500W motor delivers low-speed, high-torque performance while the handle control keeps operations safe and precise, especially when working in tight or awkward positions. Electrodeless speed regulation and automatic feed shutoff at the limit switch mean you can dial in the cut and let the machine handle the rest, achieving Ra3.2 surface roughness and roundness deviation under 0.02mm even in field conditions.
