The C-Hog Bevelling Machine

The C-Hog Bevelling Machine securely attaches to the tube O.D. with a huge clamp that minimizes chatter and vibration and is well suited for small bore tubes because there is no I.D. clamp or mandrel to interfere.

The I.D. clearance gained also allows for large, tough I.D. boring blades that increase Cutter Blade endurance.

Designed for maximum operator comfort, efficiency and ease of use, the C-Hog’s attached feed wrench lets the operator comfortably feed the tool as it bevels the tube with minimal fatigue.

Constructed to deliver reliable performance on the toughest applications, the C-Hog is a rugged tool that is light weight and compact.

Highly engineered, it incorporates state of the art materials and heat treated components.
