Product Description
Product Overview
PDC Matrix Body 8-inch drill bits are engineered for optimal performance in very hard geological formations including quartzite and volcanic rock. These industrial-grade drilling tools feature polycrystalline diamond composite cutters brazed onto a durable matrix body for superior wear resistance and cutting efficiency.
Technical Specifications
Bit Size: 8 inches (203.2 mm)
Body Type: Matrix body construction
Formation Compatibility: Very hard formations (8 on formation scale)
Cutter Type: Polycrystalline Diamond Composite (PDC)
PDC Technology Advantages
PDC cutters combine polycrystalline diamond layers with cemented carbide substrates using high-temperature, high-pressure sintering at approximately 2800°F and 1,000,000 psi. This process creates cutting elements with exceptional wear resistance and fracture toughness.
Formation Compatibility Scale
| Formation Type | Description |
|---|---|
| (1) Very Soft | Highly drillable formations: clay, marl, gumbo, unconsolidated sands |
| (3) Soft-Medium | Low compressive strength sands, shale, anhydrites with hard layers |
| (4) Medium | Moderate compressive strength sand, chalk, anhydrite, shale |
| (6) Medium Hard | Higher compressive strength with non-or semi-sharp sand, shale, lime, anhydrite |
| (7) Hard | High compressive strength with sharp layers of sand or siltstone |
| (8) Extremely Hard | Dense and sharp formations: quartzite, volcanic rock |
