1.PDC drill bit is super hard material combined with diamond and hard alloy under high temperature. It has the advantages of hard and durable from diamond, and has the advantages of high impact resistance and big blade from hard alloy. It greatly improves the drilling efficiency and is the ideal drill bit for the drill operation of medium & hard as well as super hard rock. 2. The carrier of PDC bits is forged and pressed by first-class steel. Its mechanical capacity is strengthened by fully automatic vacuum heat treatment equipment. 3.The ordinary type adopts Chinese PDC as its blade, while the super-strong type adopts American blade made by GE. Choosing proper type makes high ratio of performance and price. 4.Our PDC drill bits are widely used in all industries, such as coal mining, oil exploration, geological exploration, water and hydroelectric, railway and road, tunneling construction and so on. 5.Two-wing PDC anchor bits (semi-round standard type) is applied to the hardness not bigger than f8. The working life is 10-30 times of the ordinary alloy bits, and the efficiency could be improved by 60%. Besides, the PDC bits don't requires figuring, which lows the labour intensity and helps to saves cost. 6.GE, American company, produces the main material of the blade for two-wing PDC anchor bits (semi-round strengthened type). The diamond content is 1.5 times of the ordinary bits, which has excellent abrasive resistance and applied to medium and hard rock (fâ?¤12). Super strengthened PDC bits adopts newly designed ball type diamond as its blade. Features: fast drilling speed, high impact resistance. 7.When the drill bits work, the edge is used to cut ordinary and symmetrical formation, while the ledge acts as cushioning to avoid huge drilling footage, which helps to low the possibility of damage. Thanks to that, the drilling level of complicated formation is improved.High-efficiency Reaming Bit and button drill bit tapered drill bits

PDC cutters different features are selected and bit profile design is optimized to suit different drilling applications in different formations to satisfy different requirements when drilling soft to medium hard formations without sulfureted hydrogen well section. Cutting structure is force balanced,non-symmetrical blade and deep junk slots are designed to dramatically improve ROP of the bit.Matrix material of the bit adopts high quality steel and wear-resistance material with high performance is build-up welded on the surface of blades to prevent material from eroding. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling. Machining precision and retention of cutters are ensured by using milling center with high performance five axes and high speed milling technology.

1.The description of PDC Bits PDC Bit uses PDC 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 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. We can supply all kinds of PDC Core drill bits and non-core drill bits and they are widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway and provide reliable data support for drilling rock and coal of geology and engineering research. We can also design PDC bits according to customers' requirements, such as different geological condition, special strata and so on. PDC (polycrystalline diamond compact) drill bit is produced with special high-frequency welding techniques and manufactured by welding PDC of high wear resistant Si to the steel body as cutting edges. 2.The Features of PDC Bits: A: Super long life. The grinding/consumption ratio of PDC is 20-40 times that of tungsten carbide bit and 10 times that of diamond bit. B: High drilling speed. C: Can be operated with low pressure and low speed. D: Has a good gage protection. E: Can be used widely, more suitable for drilling in the stratum with formation< 7. F: Low cost. G: High toughness and impact strength
