High-Efficiency PDC Core Bits for Soft to Medium Strata Drilling
When encountering soft, loose, or medium-hard geological formations, maintaining a high Rate of Penetration (ROP) while securing a high core recovery rate can be challenging. Bloom Machinery’s PDC (Polycrystalline Diamond Compact) Core Bits are specifically engineered to solve this. Utilizing premium gold-coated PDC cutters strategically layout on high-strength steel crowns, these bits utilize an aggressive shearing action rather than grinding, which delivers unmatched drilling speed in non-competent rocks.
The advanced cutter placement layout maximizes face cleaning and eliminates bit balling, even when drilling through sticky clay, shale, or soft limestone. Engineered with standard API and wireline thread profiles (NQ, HQ, PQ), our PDC core bit series offers field-proven impact toughness, stable tracking, and an exceptionally long service life, making it the most cost-effective solution for large-scale coalfield exploration, oil & gas environmental testing, and geotechnical water-well boring.
Cutter Layout Style | Target Formations | Recommended Applications | Technical Advantage & Design |
Flat Face / Standard Cutters | Soft & Homogeneous (Grade 1-3) | Coal beds, Mudstone, Soft Clay, Siltstone | Maximum surface contact for rapid, continuous cutting. Eliminates bit vibration in uniform formations. |
Ribbed / Stepped Face Profile | Medium Hard & Interbedded (Grade 4-6) | Medium Limestone, Abrasive Sandstone, Dolomite | Stepped layout concentrates drilling pressure, making it easier to break through interbedded hard layers without cutter chipping. |
Heavy-Duty Gage Protection | Heavily Fractured / Interbedded Zones | Fault zones, Overburden layers, Broken strata | Features extra tungsten carbide inserts on the outer gauge to prevent bit diameter shrinkage and borehole deviation. |
