Below is pictured drilling 2″ holes through hinge pins on a Oil Drilling Rig roof working from a manlift 40′ in the air. The work was done with a portable hydraulic powered Drill with #5 MT spindle and 3″ capacity. Generally, as in the picture below, we make custom jigs to mount the drill to the customer’s project.
We also have various magnetic drills for either drill bits or annular cutters. The job pictured below was done on another Oil Drill Rig working suspended in a cable basket.
