Product Introduction

Todaone PDC coring bit features high-performance polycrystalline diamond cutters combined with a robust steel body, ensuring efficient coring and excellent wear resistance. Designed for complex formations, it provides stable extraction of high-quality core samples, widely used in oil & gas exploration and geological surveys to enhance drilling accuracy and efficiency.

Product Feature

High-efficiency cutting performance

Adopting high-quality polycrystalline diamond (PDC) cutters, it has excellent wear resistance and strong cutting capability, significantly improving coring efficiency.

High core integrity

The specially designed coring structure and optimized core barrel channel effectively reduce core breakage and blockage, ensuring the core remains intact in shape and facilitating subsequent analysis.

Sturdy and durable structure

With a reasonable blade design, it features high rigidity and good impact resistance, capable of withstanding high-intensity bit weight and impact loads in complex formations.

Efficient fluid flow system

Equipped with a precise internal hydraulic structure and unobstructed flow channels, it effectively cools the cutting teeth and removes cuttings in a timely manner, preventing core barrel jamming and overheating.

Multiple structure options available

Two types are provided: matrix type (high wear resistance) and steel body type (high toughness, repairable), adapting to different drilling environments and budget requirements.

Wide range of applicable formations

Especially suitable for medium-hard to hard formations such as shale, limestone, mudstone, tight sandstone, etc., and widely used in industries like petroleum exploration, coalfield geology, and hydrogeology.

Diversified sizes and interfaces

Can be customized with different specifications, sizes, and threaded interfaces according to customer requirements, compatible with mainstream coring tool systems, with strong adaptability.
