Product Introduction
PCD bit is mainly used for drilling soft and medium formation, it work under low drilling pressure,medium-low speed, big drainage. PDC(polycrystalline diamond compact) drill bit is a new product after the hot-pressed and electroplated drill bit recent years. With special high-frequency welding techniques.PDC of high wear resistant si welded to the body as cutting edges.PDC bit is mainly used for geological prospecting,coal exploration,water conservancy and power engineering,etc.
Product Introduction
1. It has a super long life. The grinding/consumption ratio of PCD is 20-40 times that of tungsten carbide bit and 10 times that of diamond bit. 2. It had high drilling speed. 3. It can be operated with low pressure and low speed. 4. It has a good age protection. 5. It can be used widely, more suitable for drilling in the stratum with formation<7. 6. It has a low cost.
