PDC core bit with ISO9001 certification

What Makes a PDC Core Bit Different

A PDC core bit uses polycrystalline diamond compact cutters — synthetic diamond layers bonded to tungsten carbide substrates — to shear through rock formations rather than crushing them. This cutting mechanism delivers faster penetration rates and longer bit life compared to conventional surface-set diamond bits, especially in soft to medium-hard formations such as shale, limestone, claystone, and sandstone.

Unlike a full-face PDC bit designed for non-coring applications, a PDC core bit features an annular cutting face that preserves a central core sample for geological analysis. This makes it the tool of choice for mineral exploration, geotechnical investigation, and water well drilling where formation evaluation is critical.

ISO9001 Certification: Why It Matters for Your Drilling Program

ISO9001 is the most widely recognized quality management standard in the world. For a PDC core bit manufacturer, holding this certification is not a one-time achievement — it requires ongoing external audits that verify every aspect of production, from raw material procurement to final inspection.

In practical terms, this means the core bit you receive today will perform the same way as the one you ordered six months ago. Consistency is what separates a certified supplier from an uncertified workshop.

TY Drill Bits: PDC Core Bits Built to ISO9001 Standards

TY Drill Bits (Xi'an Heaven Abundant Mining Equipment CO.,LTD) has been manufacturing drilling tools since 2010 from our facility in Xi'an, China. We hold ISO9001 certification and export over 90% of our production to customers across Asia, Africa, South America, and the Middle East.

Matrix Body PDC Core Bits

Our matrix body PDC core bits are manufactured by infiltrating tungsten carbide powder with a copper-based binder around a steel blank, creating a tough, wear-resistant crown that holds PDC cutters securely. This construction excels in abrasive formations and high-temperature drilling environments. Available in BQ, NQ, HQ, and PQ sizes with standard wireline or conventional shell configurations.

Steel Body PDC Core Bits

For water well drilling and shallow exploration, our steel body PDC core bits offer a cost-effective alternative. Machined from alloy steel with precision-set PDC cutter pockets, these bits provide excellent penetration rates in soft to medium formations. Common diameters range from 75mm to 150mm with API or metric thread connections.

Custom PDC Core Bit Solutions

We understand that no two drilling projects are identical. Our engineering team can customize cutter size (1308, 1313, 1613), blade count, waterway design, and thread connection to match your specific formation conditions and rig specifications.

Quality Control Under ISO9001: A Step-by-Step Look

Every PDC core bit that leaves our factory passes through a documented quality control workflow:

This documented process is what ISO9001 auditors review during surveillance visits. It is not a one-time check — it is a system that runs every day, on every bit.

Applications Across Industries

Mineral Exploration

In greenfield exploration, core recovery rate directly impacts resource estimation accuracy. Our ISO9001-certified PDC core bits consistently deliver recovery rates that meet JORC and NI 43-101 reporting standards. Available in BQ, NQ, and HQ sizes for both surface and underground drilling rigs.

Water Well Drilling

For water well contractors, the combination of penetration speed and bit life determines daily productivity. Our steel body PDC core bits run efficiently on common water well rigs, and can be paired with our PDC bit range for non-coring sections of the same borehole.

Geotechnical Investigation

Site characterization for dams, bridges, and high-rise foundations demands undisturbed core samples. Our PDC core bits maintain dimensional stability throughout extended runs, preserving sample integrity for laboratory testing.
