BQ NQ HQ PQ Surface Diamond Bits For Geological Prospecting
Application:
Yaheng impregnated diamond core bits are the most commonly useful bits in the mineral exploration industry, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series.
"Yaheng" brand is a famous global brand.

Yaheng Surface set Diamond Core Bits are mostly suited to soft formations or using low powered drills, as they operate more effectively than impregnated bits at low surface speeds. Available with different stone sizes, face profiles and waterway arrangements to suit different conditions. All supplied with highest quality natural drilling diamonds.

Surface-Set Non-coring Bits are drilling for broken formation rock which can't be cored. Crown are used to set with synthetic, natural or polycrystalline diamond. It's used for drilling in soft to medium hard formation rocks.

Surface set diamond bit is produced from a single layer of natural diamond setting on the surface of bit crown with hard matrix.

Surface set diamond bit is mainly recommended for drilling soft to hard formations. Generally speaking, surface set diamond bit can provide satisfying penetration rate.
To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.
