Hot-Pressed Wireline Core Bit

The Hot-Pressed Wireline Core Bit is designed for high-efficiency core drilling in mineral exploration and deep geological investigation. Manufactured using hot-press sintering technology, this bit features strong diamond retention, excellent wear resistance, and stable performance in a wide range of formations.
It is widely used in wireline drilling systems where fast core retrieval, high penetration rate, and long service life are required.

The Hot-Pressed Wireline Core Bit is specifically engineered for professional core drilling operations where productivity and core quality are critical.
Through hot-press sintering technology, diamonds are uniformly distributed and firmly bonded into the matrix, ensuring consistent cutting performance and excellent resistance to wear.
It is compatible with standard wireline systems such as BQ, NQ, HQ, PQ, NQ3, HQ3, and PQ3, making it suitable for a wide range of exploration projects.

The client switched to our Hot-Pressed Wireline Core Bit (HQ size).

Results:

Bit life increased by 30–45%

Improved penetration rate

Reduced drilling downtime

More stable core recovery

"The bit performance was very stable in hard formations. We reduced bit consumption significantly and improved daily drilling output."

Match bit hardness with formation type

Maintain stable WOB and rotation speed
