Audited Supplier The tricone bit consists of three rotating cones working inside each other and each with its own row of cutting teeth.
The tricone bit has three roller cutter cones with a series of teeth that crush rock on the rock face as they roll over the face.
A tricone bit is a drill bit with a head that is divided into three main parts.
| Bit Size | 17 1/2'',444.5mm |
| IADC Code: | 537G |
| Thread Connection | 7 5/8 API REG PIN |
| Series | HR series rubber sealed bearing |
| Nozzle Qty | 3NZ |
| Weight | 260KG |
| WOB(kN/mm) | 0.45-1.0 |
| RPM(r/min) | 120-50 |
| Formations | Soft to medium formation |
The way the tricone breaks through the rock is by using its multitude of very small chisel shapes, which protrude from a roller. These are pushed into the rock by the rods that connect it to the surface, and the weight is distributed evenly to break through.
The biggest advantage the tricone bits have over any other drill bit is the test of time. They have been proven time and time again, and they're the best at controlling the trickier situations. Tricones' ability to handle both soft and hard formations gives them the flexibility that other drill bits do not have.
