Published fields to check.
These are selected catalogue fields from the source below. They do not establish availability, an accepted specification or compatibility with your machine.
| Field | Supplier-listed value |
|---|---|
| Listed body construction | Steel body |
| Selected three-wing table diameters | 76, 89, 102, 127 and 152 mm |
| Other listed wing arrangements | Four- and five-wing rows exist for selected sizes; quote separately |
| Connection / operating limits | Exact thread, drawings and model-specific limits required |
What still needs confirmation?
The summary size range and full dimensional table do not agree at their endpoints. We publish a subset of explicit three-wing table rows, rather than resolving the discrepancy by inference. A three-wing PDC drag bit is not a DTH button bit or a core-recovery barrel / bit system. No drilling-speed, lifetime or universal hard-rock performance claim is adopted.
