The Fin MILLHOG tube fin removal machine clamps to the tube I.D. and features a patented cutter blade that separates fin from tube O.D. — removes 4" of fin in under 4 seconds. Forget chipping hammers and grinders.

The Fin MILLHOG tube fin removal machine clamps to the tube I.D. and features a patented cutter blade which separates fin from tube O.D. Forget about chipping hammers and grinders. This machine removes 4″ / 101.6mm of fin from a tube O.D. in under 4 seconds.

Once the tool is attached to the tube I.D. and the power is activated, the operator advances the rotating cutter and engages the spirally wound fin until the desired amount of fin is removed. The quick action of the rack and pinion feed allows the operator to disengage the feed and clear separated fin from the cutter quickly.
