The Disengageable Mill Assembly allows conventional liner-top PBRs/ TBRs to be
dressed off or cleaned in the normal manner. |
| Disposable BRISTLE BACK Casing Cleaning Tool (CCT)

The Pressure Shear Sub (PSS) is specifically designed to be run in a drillstring to apply temporary pressure for actuating another tool above the
PSS, such as a near-bit reamer. |
 | Razor Back CCT with Integral Top Dress Mill (RBTDM)

The RAZOR BACK* CCT* (Casing Cleanup Tool) with Integral Top Dress Mill ensures that the casing is scraped to a point very close to the top of the liner so that subsequently installed liner-top tieback packers will be set and sealed. |
