Maximize your underreaming with a Holte URE designed to have a wider cutting edge where you need it most. The Holte oval shape places more cutting edge on the bore hole wall. The URE Drive Shoe Style Underreamer is similar to the Casing driver style except the driver portion has a drive shoulder. This shoulder drives down the drive shoe that is welded to the casing. With this system, the down hole hammer is used to both drill and drive casing.
Eccentric Overburden Systems are available between 5" - 12".
