Coal drill bits

Description

PDC bit uses PDC as main cutting components, with the excellent wear-ability and impact toughness of the PDC. It has a useful life, high-efficiency, and good performance cost ratio. PDC bit is mainly used for drilling soft and medium formation. It works under low drilling pressure, medium –low speed, big drainage. Henan zhongmei can supply all kinds of PDC coring and non-coring bits, PDC sintering matrix bits and PDC anchoring bits. PDC bit 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 your drawings or samples. Theory PDC (polycrystalline diamond compact) drill bit is a new product after the hot-pressed and electroplated drill bit recent years. With special high-frequency weldin techniques. PDC of high wear resiatance 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. The grinding/consumption ratio of PDC is ****0 times that of tungsten carbide bit and *0 times that of diamond bit. 2. It 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, more suitable for drilling in the stratum with formationï&frac*4;œ7 6. It has a low cost.
