Overview

The GMM-80R has a turnable milling head: bevel the top edge, rotate the head, and bevel the underside on the same pass along the plate. For K and X joints on heavy plate this removes the crane lift to turn the plate over, which is usually the slowest part of double-sided weld preparation.

Dual 2.2 kW milling motors, 500–1050 r/min
