Downhole Products, Ltd. Enhances Reamer Shoe Line with Patent-Pending Advancement.ABERDEEN, Scotland -- Downhole Products (DHP DHP Department of Health Professions DHP Dean Health Plan DHP Documentary Heritage Program DHP Dark Horse Presents (comic) DHP David Hyde Pierce (actor) ) has extended its technology leadership through modification of its already successful Pen-O-Trator[TM] line of reamer reamer Rotary cutting tool of cylindrical or conical shape, used for enlarging and finishing to accurate dimensions holes that have been drilled, bored, or cored. A reamer cannot be used to start a hole. shoes with the inclusion of an enhanced aluminum nose with pre-stressed zones on the exterior surface. The design modification, fueled by the request of a major international operator, assists in the break-up of the reamer shoe's aluminium nose during drill out of the shoe-track following cementing. The engineered pattern of stress zones allows the aluminium to fracture into small pieces when the drill bit encounters the inside of the nose. The smaller pieces are more easily milled, drilled and evacuated e·vac·u·ate v. e·vac·u·at·ed, e·vac·u·at·ing, e·vac·u·ates v.tr. 1. a. To empty or remove the contents of. b.

Previous reamer shoes have occasionally caused problems when large pieces of aluminum broke out and spun beneath the drill out bit reducing penetration to a near stand still.
