10 to 16 inches NB | 273 to 406.4 mm

Known as clamshell lathes, split frame cutters, or cold cutting machines in the industry, Mactech Europes portable pipe cutting machines are built for in-situ precision cutting and bevelling of all pipe sizes, schedules and materials.

The LC (Low Clearance) series is designed to fit into tight working areas as well as minimize machine weight so that engineers can machine expected high tolerances in difficult and restricted areas.  

These clamshells are lightweight but retain rigidity during operation.
