Split Frame Clamshell Pipe Cutter & Beveler

Split Frame Clamshell cold cutting a pipe in the field.

The Split Frame Clamshell is a precision OD-mounted pipe cutting and beveling tool designed for in-line maintenance, fabrication, and shutdown operations.

🔩 Split Frame Clamshell Pipe Cutter & Beveler

The Split Frame Clamshell is a field-proven solution for precision pipe machining in demanding environments. Designed for cold cutting, beveling, facing, and counterboring, it delivers weld-ready finishes on pipe sizes ranging from 1″ to 60″ OD without removing the pipe from service.

Its split-frame design allows the tool to clamp securely around the pipe’s outer diameter, eliminating the need for rotation and minimizing downtime. Modular tool slides and interchangeable cutting inserts support a wide range of machining profiles—including single-point cutting and flange facing.
