NQ Impregnated diamond bit


NQ Impregnated diamond bit is a cutting tool that embeds diamond fragments on the base material of the drill bit body and selects high-quality synthetic diamonds to be distributed in different depths of the bit body according to grades. The matrix layer of the dental crown also contains these crystals. The crystals are evenly embedded in the metal powder. This diamond tool is widely used in the mineral exploration industry.


The substrate heights that can be supplied are 6mm, 8mm, 9mm, 10mm, 12mm, and 14mm.

Features and advantages:


2.Fast footage

3.long life

4.International standard

5.Factory direct sales
