PDC Non-core Drill Bit

High-Performance PDC Non-Core Drill Bits for Efficient Borehole Creation

ZYsuperhard’s PDC Non-Core Drill Bits are engineered for high-speed, efficient drilling in applications where core sample recovery is not the objective. Designed for durability and optimal penetration rates, these bits are a reliable choice for creating boreholes in various rock formations encountered in mining, construction, and resource exploration.

Advanced Design for Superior Performance

Our non-core bits leverage the proven advantages of Polycrystalline Diamond Compact (PDC) technology combined with a robust steel body construction:

• PDC Cutters: Utilize high-quality PDC cutters strategically placed for aggressive rock shearing, exceptional wear resistance, and extended tool life, even in abrasive conditions.
• Steel Body: A tough, durable steel body provides the necessary strength and impact resistance to withstand demanding drilling operations and ensures efficient transfer of energy to the cutting face.

Key Features & Benefits

• Efficient Drilling: Optimized cutter layout and hydraulics (where applicable) for fast penetration rates and effective cuttings removal.
• High Durability: Superior wear resistance from PDC cutters minimizes bit changes and downtime.
• Robust Construction: Strong steel body withstands high impact and torque loads.
• Versatile Application: Suitable for a wide range of soft to medium-hard rock formations.
• Customizable Sizes: Available in standard diameters from Ø65mm to Ø300mm, with options for customization to meet specific project requirements.

Core Application Areas

These PDC non-core bits excel in various demanding fields:

• Coal Mining: Ideal for drilling blast holes, gas drainage holes, and water exploration holes.
• Hydropower & Infrastructure: Used in foundation grouting, tunnel construction, railway projects, and other civil engineering applications requiring borehole drilling.
• Oil & Gas Exploration: Suitable for certain shallow drilling applications and specific formation drilling needs.
• Geological Exploration & Surveys: Efficiently create boreholes for geological investigation and water well drilling.
