PDC diamond drill bits

Introduction
PDC bits uses PDCs as main cutting components, with the excellent wear-ability
and impact toughness of the PDC. It has a long useful life, high-efficiency, and
good cost performance.PDC bit is mainly used for drilling soft and medium rock, and it must work under low drilling pressure, mid-low speed and big drainage.Hebei Hanghua can supply all kinds of PDC coring and non-coring bits, and PCD Rock bits,. PDC bits can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower,
construction of road and railway.We also can design PDC bits according to customer requirements, such as different geology conditions, special strata and so on.

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. They have super long life. The grinding/consumption ratio of  PDC is 20-40
time higher than that of alloy bit and 10 times higher than that of diamond bit.
2. They have high drilling speed.
3. They can be operated with low pressure and low speed.
4. They have  good gage protection.
5. They can be used widely, more suitable for drilling in the stratum with
hardness coefficient f<9.
6.They have competitive cost.
