| Drill Bit Parameters | |
Type | Step Drag Bit 3 1/2 | |
Diameter | 89mm | |
Blades | 3 | |
RPM(r/min) | 80~60 | |
WOB(KN/mm) | 0.2~0.5 | |
API Connection | 2 3/8" API REG PIN | |
Application | ||
Softer, unconsolidated formations, encompassing clays, shale, sands, and soft limestone, perfectly suited to tackle a myriad of geological formations. | ||
Step drag bits perform best in softer, unconsolidated formations (limestone sandstone – marl). Widely used in mining, construction, exploration and water well drilling applications.
1. Step-type drag bits come in a variety of wing counts, steps and sizes to accommodate drilling in a variety of formations, from sand and clay to shale, limestone, gravel, etc.
2. Three-Wing and Four-Wing – Three-wing bits tend to drill faster, whereas four-wing bits are longer lasting, more durable, and drill a straighter hole.
3. Regular Step and Heavy Step – Regular Step bits develop smaller cuttings, whereas Heavy Step bits are more durable and are used in harder formations. Heavy Step bits have longer and wider steps and contain larger carbide for cutting. The quantity of steps is largely determined by the size of bit.
