MSD supplies steel tooth tricone bits, also called mill tooth or milled tooth bits. Compare listed sizes, API pin connections and weights before technical confirmation.
MSD Steel Tooth Tricone Bits are listed in bit sizes from 3 3/4" to 26". Use the parameter table below to compare Bit Size in inches and millimetres, API Pin, and corresponding Weight in pounds and kilograms before confirming the required configuration.
| Bit Size (in.) | Bit Size (mm) | API Pin | Weight (lb) | Weight (kg) |
|---|---|---|---|---|
| 3 3/4" | 95.2 | 2 3/8" | 10 | 4.5 |
| 3 7/8" | 98.4 | 2 3/8" | 10 | 4.5 |
| 4 1/8" | 104.8 | 2 3/8" | 11 | 5.0 |
| 4 5/8" | 117.5 | 2 7/8" | 16 | 7.3 |
| 4 3/4" | 120.6 | 2 7/8" | 16 | 7.3 |
| 5 7/8" | 149.2 | 3 1/2" | 29 | 13.2 |
| 6" | 152.4 | 3 1/2" | 30 | 13.6 |
| 6 1/8" | 155.6 | 3 1/2" | 30 | 13.6 |
| 6 1/4" | 158.7 | 3 1/2" | 30 | 13.6 |
| 6 1/2" | 165.1 | 3 1/2" | 31 | 14.1 |
| 6 3/4" | 171.4 | 3 1/2" | 45 | 20.4 |

Read MoreMSD steel tooth tricone bits are the steel-tooth cutter-type products in this range. On this page, mill tooth and milled tooth are alternative names for the Steel Tooth product type.
TCI configurations use a different cutter type and are covered on the dedicated TCI Tricone Bits page. Confirm the required cutter type before comparing the listed sizes and connections.
Start with the required hole diameter and review the exact table entry. The current MSD table lists Steel Tooth tricone bit sizes from 3 3/4" to 26", with the corresponding millimetre size, API Pin, and weight information shown for each entry.
Formation conditions should be provided separately because the current table does not assign a formation to each listed size. Provide the formation description and available information from the existing bit or drilling record for technical review rather than selecting from diameter alone.
The API Pin listed for the selected steel tooth tricone bit must match the mating connection in the rotary drill string. Nominal bit size alone does not confirm connection compatibility.
For an existing system or replacement requirement, provide the mating connection, drill-pipe or sub connection information, current bit markings, and available photographs or drawings. These details allow the listed API Pin and the required drill-string arrangement to be checked together.
Steel tooth or mill tooth tricone bits on this page can be reviewed for water-well drilling requirements. The final configuration should be confirmed from the required hole diameter, formation conditions, drill rig, and mating connection rather than from the application name alone.
For technical confirmation or quotation, provide the required bit size, formation description, API Pin or mating connection, drill-rig and drill-string information, current product details where applicable, required quantity, and any additional configuration requirements.
