Abstract
Disclosed is an Angle Drilling Apparatus for mobile rotary drills and the like having a mast tower for operating and supporting the drill string. A transferable and adjustable lower pivot support is provided in combination with the normal mast raising cylinders and a unique upper mast support strut. The upper mast strut is slideably attached to the mast and provides support to the mast closer to the top of the mast as the mast is deployed at an angle for angle drilling. The adjustable lower pivot support allows drilling to be accomplished closer to the support base and more nearly at the point of vertical drilling.
