Noting!
We also can design diamond bits according to customer requirements, such as different geology conditions, special strata and so on.
Introduction
The impregnated diamond 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.
Theory
PDC (Polycrystalline Diamond Compact) drill bit is a new product after the hot-pressed and electroplated drill bit in recent years. With special high-frequency welding techniques, PDC of high wear resistant is welded to the body as cutting edges. PDC bit is mainly used for geological prospecting, coal exploration, water conservancy and power engineering, etc.
Features
1. It has a super long life.
2. It has high drilling speed.
3. It can be operated with low pressure and low speed.
4. It has a good gage protection.
5. It can be used widely,suitable for drilling in all kinds of hardnessrocks 6. It has a low cost.
