BQ, NQ, HQ, PQ Diamond Impregnated Core Drill Bits | High-Performance Geological Drilling Tools
We offer a full range of diamond core drill bits designed for geological exploration, mining, and geotechnical drilling projects. Depending on the drilling formation and cutting media, we provide several specialized types of core bits:
1. Diamond Impregnated Core Drill Bits
Impregnated diamond core bits are manufactured using high-quality synthetic diamonds evenly mixed in a metal alloy matrix. As the matrix wears down, new diamonds are continuously exposed, ensuring consistent cutting efficiency through hard rock formations. These bits are cost-effective for most geological core drilling applications and offer longer tool life with high drilling performance.
2. Surface-Set Diamond Core Drill Bits
Surface-set diamond bits feature a single layer of natural or synthetic diamonds embedded on the crown with a hard matrix. Recommended for soft to hard formations, they provide fast penetration rates and reliable drilling performance, making them ideal for projects requiring high productivity.
3. PDC (Polycrystalline Diamond Compact) Core Bits
PDC core bits are set on the crown to achieve long working life, very fast penetration, and high core recovery. They are an excellent alternative to TC bits and surface-set diamond bits, especially for soft to medium-hard formations, offering efficient drilling with minimal downtime.
4. PCD Core Bits
PCD core bits are designed for soft to medium-hard formations such as limestone, sandstone, marble, basalt, and clay. Specially shaped PCD inserts in the matrix provide maximum exposure, wear resistance, and high penetration rates, resulting in long durability and efficient drilling performance. Ideal for geotechnical and specialized drilling applications.
