Product Description
This 45 mm threaded reaming bit converts to 1.77 in and is classified as a Milling Bit because the source filename repeatedly identifies Reaming geometry. It is positioned for plug-milling and well-workover tasks that require a reaming head rather than a primary formation bit. The allowed uses can be reviewed in the plug milling archive and the well workover archive.
The media name supports an alloy reaming body, a 45 size reference, threaded construction, and button-style cutting elements. It does not state whether “Thread 45” means T45 or a 45 mm proprietary interface, so the connection is recorded cautiously and must be verified on the actual tool. Inspect the reaming gauge, cutter retention, body wear, and thread condition. No IADC, bearing, or datasheet value is claimed for this milling-family item. Measure the reaming diameter at several points and reject a head that is eccentric, since uneven gauge contact can damage the workover path and the mating assembly.
The project fact table gives no numerical WOB, RPM, or flow range for milling and workover reaming tools, so those specification fields remain empty. Set operating controls from the supported procedure and assembly rather than borrowing Button/DTH or tricone numbers. API thread background is available from the American Petroleum Institute. This product is limited to reaming and workover service; it is not represented as a general hard-rock production bit. Stop and inspect if cutters loosen, gauge changes, or the thread shows damage. Retain the worn head for dimensional review. Photograph the verified thread marking.
