DRILLSTAR Economill is a low-cost mill, ideal for milling tubular equipment. It will also shave off
cement in drill pipes and tubings or mill bridge plugs and retainers.
Main advantages
The Economill can be air freighted at low cost for urgent jobs. Made
with a standard rock-bit connection, it can be easily adapted to drill
stem stabilizers or used inside a skirt to mill fish heads.
A large central hole gives improved mud flow, facilitating the
evacuation of cuttings. Other small holes allow a perfect cleaning of
the blade design ensures perfect stabilization and centering in the
casing. Drillstar Economill can be used with a turbodrill.
