Product Description
This 38–40 mm ball-tooth anchor bit covers 1.50–1.57 in and is classified under Workover Bits because the media filename explicitly identifies an anchor-rod drilling product. It is positioned for well-completion or workover support tasks in medium, consolidated material where the verified anchor system accepts the bit. Review the well completion archive and the well workover archive for the permitted application terms.
The source name lists a 40 mm bit, a 38 mm ball-tooth reference, and an anchor-rod context. The body is recorded as alloy steel with carbide ball teeth. It does not identify a standard thread, so the anchor connection must be confirmed on the physical product. Inspect tooth retention, face symmetry, gauge, and the mating rod before use. No IADC, bearing, circulation, or datasheet claim is added. Check every tooth pocket for cracking and compare the face against the rod axis; a tilted anchor head can create side loading before any obvious carbide loss appears.
The fact table does not provide WOB, RPM, or flow ranges for Workover Bits, so these fields remain blank rather than copying Button/DTH numbers from a different category. Set controls from the verified anchor and completion procedure. API standards background can be reviewed through the American Petroleum Institute. This product is limited to the supported anchor/workover role and is not presented as a general open-hole hard-rock bit. Stop after tooth loss, gauge change, or connection damage and inspect the assembly. Record the mating rod with the dull report. Measure gauge before final storage.
