Casing shoes are installed on the leading edge of casing tube strings to advance them through overburden layers and into bedrock using rotational drilling. The cutting media on the core bit may utilize synthetic diamond, tungsten-carbide particles, or tungsten-carbide elements depending on application requirements.

• High penetration rate for efficient drilling operations
• High core recovery ratio for accurate geological sampling
• Long service life with durable construction
• Cost-effective performance for drilling projects

All Chinese standard sizes available

Crown Height: Available in 9mm, 12mm, and 16mm impreg depths. Taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.

Waterways: Various waterways available for diamond impregnated bits to optimize flushing in different ground conditions and drilling systems.

Matrix: Impregnated bit matrices can be selected by our engineers according to ground conditions at your work site.

Threads: Standard Q threads as well as custom thread types required by clients are available.

SINOCOREDRILL bits are available in all standard drilling sizes. Non-standard sized bits can be produced according to specific client requirements.
