BQ NQ HQ PQ Impregnated Diamond Core Drill Bit 14mm For Mining Exploration

Bits are manufactured with very small, high quality synthetic diamonds, mixed evenly through a metal alloy matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. In most geological formations, impregnated bits are more economical to use than other bits.

The application of impregnated diamond bit range from medium to ultra-hard formations. The bit’s crown is made up of a metal powder and diamond matrix that wears away during the drilling process and exposes new layers of diamonds, renewing the cutting points. The combination of diamond and proprietary matrix result in the optimal performance.

Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

Size：

Sinocoredrill bits are available in all standard drilling sizes(BQ,NQ,HQ,PQ,etc.)

Also, non-standard sized bits can be produced according to requirements from clients.

Crown Height:
Sinocoredrill offers crown depths of 10mm, 12mm, 14mm.

The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance. Unless otherwise specified, a standard 14mm impregnation depth is supplied for most of our customer.

Waterways: 

Various waterways are available for diamond impregnated bits.

Differing waterways allow for better flushing in various ground conditions and drilling systems.

Matrix hardness:

For convenience of customer from different countries, Sinocoredrill impregnated bit matrices adopts the international standard matrix number system. Matrices to be used on various rock conditions can be ordered according to the MATRIX SELECTION CHART.

Threads:

Standard Q threads DCDMA as well as thread types required by clients are available.
