PanelMill

KRAIS Tube Expanders

The PanelMill attaches to the tube outside diameter by means of custom or specific clamp type jaws that provide strong clamping action that minimizes chatter and vibration.
Rugged construction allows the tool’s cutting blade to end prep quickly. Several cutter heads are available for tubes with up to 2-1/2” O.D.
Both the clamp and cutter heads are extremely durable and easy to change.
The ratchet feed arm enables the operator to comfortably feed the tool during bevelling or facing. The PanelMill is suitable for small bore heavy wall tubes with a high percentage of chrome, stainless steel, and other exotic alloys. Standard and custom made blades are offered in a wide variety of angles and sizes.
