Underream the hole to diameters many times larger than the original hole.
Circulation through bottom of blades with optional fluid expulsion out of the blade ends for an even larger diameter.
Horizontal underreamer. Underream to slightly larger diameters than the original hole. Mill section or cut pipe.
Multiple blades (6 or 3) allows better centralization and hole tracking especially in horizontal underreaming, mill sectioning or casing cutting.
Normal or reverse circulation
Blades replaceable on location for reduced drilling costs.
Various blade profiles and/or cutter rake angles possible with additional blade sets.
Drill bit with expandable blades for well bores with diameter restrictions above but more hole to drill with no existing hole to underream from.
Deep penetration of projectiles into rock.
Communicate far beyond any well bore skin damage.
Projectiles micro fracture rock and intersect natural fractures.
