Product Description

The impregnated diamond bits have the widest range of application. They are the most commonly useful bits from medium to super hard formations in the mineral exploration industry.

Toothed bits can get higher drilling efficiency when it is drilling at dense or abrasive stratum with lower drilling speed and pressure. It was especially effective at coal formation, using toothed bits can get better water flowing and drilling footage effect. Nowadays, the impregnated diamond bits have been widely used in wire-line drillinng series.
